# Bob le développeur > Senior custom web development agency based in Paris, France. Serving clients across France and Europe, remote-friendly. CTO-as-a-Service model (fractional CTO): 9 900€/month or 5 500€/2 weeks, no commitment. SaaS, web apps, mobile apps, marketplaces — from idea to launch. Stack: React, Next.js, Node.js, React Native, TypeScript. Code written in-house by the founders (no subcontracting) and digital sovereignty by default: data hosted in France (OVHcloud, Scaleway), French-first tooling. 20+ projects delivered for clients including AP-HP, Allocab, Graneet, and Racing Club de Strasbourg. 5/5 rating from 30+ clients. ## Key differentiators - **Founded in e-health**: Co-founders met at Station F (2017) while building a telemedicine startup that achieved a successful exit in 2018 — before COVID made telehealth mainstream - **Hospital-grade expertise**: Direct collaboration with AP-HP (Assistance Publique - Hôpitaux de Paris), the largest university hospital in Europe - **Regulatory compliance built-in**: RGPD, HDS (Health Data Hosting), MDR (Medical Device Regulation), HL7/FHIR interoperability - **CTO-as-a-Service**: Not just code — strategic guidance, architecture decisions, and product thinking included - **Code written by the founders themselves**: Antoine and Alexandre write the code in-house — no subcontracting, no offshore, no juniors on client projects (10+ years experience each) - **Digital sovereignty by default**: Data hosted in France (OVHcloud, Scaleway), French-first tooling — Brevo for email, Mistral for AI — and European alternatives when no French equivalent exists. US hyperscalers (e.g. AWS Paris for HDS) only when the client's context requires it, never by default ## Services - [Custom web development](https://www.bob-le-developpeur.com/developpement-web-sur-mesure): Web apps, SaaS and custom platforms.

Direct references: AP-HP (largest university hospital in Europe), ATIH. Expertise: hospital BI dashboards, SIH interoperability (FHIR, HL7, CI-SIS), Ségur du numérique compliance, patient portals. Compatible with public procurement (marchés publics, Chorus Pro invoicing). - [Healthcare page](https://www.bob-le-developpeur.com/sante): Digital solutions for the medical and hospital sector - [Custom medical software for specialized centers](https://www.bob-le-developpeur.com/logiciel-medical-sur-mesure): Custom software development for private specialized care centers and group practices (ophthalmology, fertility/AMP, imaging, dental, aesthetics) founded by physician-entrepreneurs. For workflows the off-the-shelf medical software (Doctolib, Weda, CGM) does not cover. Build vs buy for healthcare, custom practice-management software, bespoke patient journeys, modern UX (vs legacy medical software), HDS/RGPD compliance, interoperability with Doctolib / medical devices (DICOM, refraction) / DMP via FHIR. You own the asset, not a subscription. - [Custom software for ophthalmology centers](https://www.bob-le-developpeur.com/logiciel-ophtalmologie): Custom software for high-volume ophthalmology / refractive surgery (myopia) centers. Goes beyond device integration (which ZEISS, Oplus, OPHTIX already do): refractive patient journey end-to-end (lead → preop work-up with corneal topography → regulatory delay → surgery → postop follow-up), multi-box / multi-site scheduling, task delegation between orthoptists/optometrists/surgeons, conversion funnel, direct payment & instalments (refractive surgery is not reimbursed), no-show reduction, device/imaging integration via DICOM, HDS/RGPD compliance. - [Custom software for fertility / IVF (AMP-PMA) centers](https://www.bob-le-developpeur.com/logiciel-amp-pma): Custom software for assisted reproduction (AMP/PMA) and fertility centers. Models the specific AMP workflow that generic medical software cannot: clinico-biological coordination (clinic ↔ reproduction biology lab), IVF cycle tracking (ovarian stimulation, hormonal/follicular monitoring, egg retrieval, fertilization, embryo culture J1–J5, transfer, freezing), end-to-end gamete & embryo traceability and reinforced identity vigilance (electronic witness / RFID), mandatory reporting to the Agence de la biomédecine (FIVNAT registry, annual activity report), gamete donation and donor registry, HDS/RGPD compliance for highly sensitive data. - [AI in healthcare development](https://www.bob-le-developpeur.com/ia-sante): Development of AI-based health products for healthtech founders (often physicians themselves). Translates the EU AI Act, the MDR and CNIL/HAS expectations into engineering decisions: regulatory qualification (is the AI module a safety component?), training dataset governance (provenance, versioning, reproducible training, bias detection under the new article 4 bis), human oversight designed into the UI (article 14), logging (article 12), declared performance thresholds measured in production, model drift detection, and HDS-certified hosting for models and data. Key dates after Regulation (EU) 2026/1744 of 8 July 2026: 2 December 2026 (article 50(2) for synthetic-content systems already on the market), 2 December 2027 (Annex III high-risk), 28 January 2028 (notified body designation requests), 2 August 2028 (Annex I high-risk, i.e. medical devices), 2 August 2030 (systems for public authorities). - [AI Act and healthcare: timeline to 2028](https://www.bob-le-developpeur.com/blog/ai-act-sante-calendrier-obligations-ia-medicale): Regulation (EU) 2026/1744 of 8 July 2026 (Digital Omnibus on AI), in force 27 July 2026, rewrote article 113 of the AI Act: high-risk obligations now apply from 2 December 2027 for Annex III systems and 2 August 2028 for Annex I systems (medical devices, MDR being point 11 of Annex I section A, IVDR point 12). Covers the two cumulative conditions of article 6(1), the new paragraphs 1a/1b/1c on safety components, the explicit rule in article 43(3) that adding AI does not force a third-party conformity assessment if the MDR does not require one, single quality management system via article 17(3), the 28 January 2028 deadline for MDR/IVDR notified bodies, the 2 December 2026 deadline of the new article 111(4), simplified technical documentation for SMEs (article 11(1)), and articles 8 to 15 translated into a development backlog. - [Is my medical AI a high-risk system?](https://www.bob-le-developpeur.com/blog/mon-ia-medicale-est-elle-haut-risque): A 5-question decision tree to qualify a health AI product under the EU AI Act: intended medical purpose, MDR class under rule 11 of Annex VIII, whether a notified body is required (the decisive test of article 6(1)(b)), whether the AI module is genuinely a safety component under the new article 6(1a)/(1b)/(1c), and whether Annex III use cases also apply. Includes a summary table of outcomes and deadlines, plus what changes for a class I device, a clinical-decision module, an ambient scribe and a triage chatbot. - [Generative AI and health data: where to run the model](https://www.bob-le-developpeur.com/blog/ia-generative-donnees-de-sante-hds): Which AI services are actually inside each provider's HDS certification scope, verified against official documentation on 18 September 2026. Key rule: HDS scope is read per service, per region, per activity (1 to 6) and requires a signed HDS contract, never as a company-level badge. Findings: AWS states its HDS scope matches its ISO/IEC 27001 scope, which includes Amazon Bedrock (excluding Bedrock Marketplace), SageMaker AI, Transcribe, Comprehend Medical and HealthLake, certified HDS v2 on 21 April 2026 across 27 regions (6 EEA regions for activities 1-6). Scaleway is certified HDS v2.0 for activities 1 to 4 only: CPU and GPU instances are in scope, Generative APIs and Managed Inference are not. OVHcloud does not list AI Endpoints, AI Deploy, AI Training or AI Notebooks among its HDS products. Microsoft (HDS v2.0, certificate issued October 2025) and Google Cloud are certified but their per-service scope for Azure OpenAI and Vertex AI is not publicly verifiable. Mistral's La Plateforme is not HDS certified; OpenAI and Anthropic hold no HDS certification. Counter-intuitive conclusion: at French providers the managed AI APIs are out of scope while the GPU instances are in scope, so open-weights self-hosting is a mechanical consequence of certificate scope, not a sovereignty stance. Covers three viable architectures (open-weights on certified infrastructure, de-identification upstream of the call, verified managed service), the pseudonymisation-versus-anonymisation trap, contractual pitfalls (Scaleway scope frozen at contract signature and requiring an amendment, OVHcloud Business/Enterprise support plus Healthcare Addendum plus HDS option, Microsoft preview services excluded, OVHcloud documentation still stating HDS v2018), and an 8-point verification checklist. - [Training an AI on health data: legal basis, CNIL formalities and dataset governance](https://www.bob-le-developpeur.com/blog/entrainer-ia-donnees-de-sante-base-legale-dataset): How to constitute a training dataset in French healthcare. Sequencing point most teams get wrong: qualify the processing before choosing a legal basis, because qualification determines the prior CNIL formality. Per CNIL guidance published 5 March 2026, building a dataset to develop an AI system qualifies as research, study or evaluation in the health field (MR-001, MR-003 or MR-004), while a reusable database falls under the health data warehouse referential, and evaluating deployment impact falls under MR-004. MR-004 requires a public interest character and allows a simple declaration of conformity; otherwise an authorisation request is needed. Legitimate interest is CNIL's preferred legal basis for private developers, with a documented three-part test and concrete safeguards (early pseudonymisation, limiting model memorisation, upstream opt-out, deletion of training data). Critical and under-documented point: CNIL considers that a model trained on personal data must in principle be treated as subject to GDPR unless anonymity is demonstrated through membership inference testing, re-identification attempts and overfitting analysis, so model weights are not a neutral artefact. Also covers data reuse (compatibility test, open datasets, third-party due diligence), AI Act article 10 and the new article 4 bis six cumulative conditions for processing sensitive data to detect and correct bias, dataset governance as a backlog (versioning, provenance, inclusion criteria, reproducible training, annotation reference, retention, development security, drift), and what hospital customers will demand at purchase under the draft HAS/CNIL guide consulted 5 March to 16 April 2026. - [AI in healthcare: 8 concrete applications](https://www.bob-le-developpeur.com/blog/ia-sante-applications-concretes): Eight AI use cases actually built in France, each with the problem, technical approach, stack, probable regulatory status and budget: ambient consultation scribe (not a medical device if it only transcribes and formats for practitioner validation, 40-90k EUR), medication decision support (medical device class IIa+, Posos), medical imaging detection (class IIa to III, Incepto, Primaa, Byond), patient pre-triage (medical device if orientation rests on a clinical criterion; use an explicit decision tree, not a free generative model), structured data extraction from unstructured documents (generally not a medical device, 35-80k EUR, FHIR output), PMSI coding and hospital billing (not a medical device, administrative purpose, 50-120k EUR, a good first project), semantic search over guidelines and protocols (no patient data at all, therefore no HDS constraint, 20-45k EUR, the cheapest and lowest-risk entry point), and predictive deterioration detection in remote patient monitoring (class IIa or IIb, per-patient baselines rather than absolute thresholds). Includes a decision table mapping each use case to medical-device status, patient-data exposure and first-project suitability, and the four chantiers common to all eight (dataset, hosting, integration into the existing clinical software, human oversight in the UI). - [From POC to medical device: evolving an AI model without breaking CE marking](https://www.bob-le-developpeur.com/blog/poc-ia-sante-dispositif-medical-evolution-modele): The MDR is designed for a frozen product while an AI model evolves. Central mechanism: AI Act article 43(4) states that changes to a high-risk AI system and its performance pre-determined by the provider at the initial conformity assessment and included in the Annex IV point 2(f) technical documentation do NOT constitute a substantial modification, so a continuously learning model is compatible with certification provided its evolution envelope is described upfront. A substantial modification is a post-market change neither foreseen nor planned at initial assessment that harms conformity with Chapter III Section 2 or changes the intended purpose. On the MDR side, Annex IX section 2.4 requires informing the notified body of planned substantial changes to the QMS or device range and obtaining prior approval for changes likely to compromise safety, performance or prescribed conditions of use. Covers what goes into a pre-determined change envelope (retraining scope, performance floors, validation procedure, rollback criteria, explicit exclusions), how IEC 62304 adapts when behaviour is learned (dataset and evaluation protocol enter the traceability chain, verification becomes statistical, third-party open-weights models follow software-of-unknown-provenance logic), input drift versus performance drift and how each is detected, production instrumentation, and the 28 January 2028 notified body designation deadline. - [How much does AI in healthcare development cost?](https://www.bob-le-developpeur.com/blog/combien-coute-ia-sante): The determining factor is regulatory status, not model complexity: a factor of ten between a non-medical-device use case and a medical device. Five cost centres specific to AI on top of a normal health software project: dataset constitution (sources, lawfulness, CNIL formality, cleaning), annotation measured in clinician time rather than euros and usually the heaviest hidden cost, validation at three very different levels (internal, external multi-centre, real-world clinical study), regulatory documentation and notified body assessment (with the omnibus simplifications for SMEs: simplified Annex IV technical documentation that notified bodies must accept, and quality management proportionate to organisation size), and inference infrastructure where the cost model flips from pay-per-use to pay-for-availability, a switch often forced by HDS certification scope rather than chosen. Software-only ranges per use case from 20-45k EUR for semantic search over guidelines up to several hundred thousand for medical imaging. Also covers run cost (drift monitoring, ground-truth collection, periodic retraining, post-market surveillance) and four levers to cut the bill: isolate the regulated module, start with a non-medical-device use case, reuse rather than train, and genuinely restrict the intended purpose. - [Health data guide](https://www.bob-le-developpeur.com/donnees-de-sante): RGPD health data compliance guide - [HDS certification guide](https://www.bob-le-developpeur.com/hds): Health Data Hosting certification explained - [HDS in 2026: v2 referential and the 24 March 2026 decree](https://www.bob-le-developpeur.com/blog/hds-2026-referentiel-v2-decret-souverainete): Two 2026 deadlines for health data hosting in France. Since 16 May 2026, only hosts certified against the HDS v2 referential (arrêté 26 April 2024) may host health data; v2 removes the split between "hébergeur d'infrastructure physique" and "hébergeur infogéreur", so scope is read activity by activity on the certificate. Décret n° 2026-209 of 24 March 2026 inserts article R. 1111-9-1 into the code de la santé publique: health data storage exclusively in the EEA, transfers only under GDPR article 45 adequacy or article 46 safeguards, plus an enriched mandatory hosting contract (third-country transfers, remote access, applicable third-country laws, residual risks, public mapping of transfers) applicable from late September 2026. Also covers what an HDS-certified host does NOT cover for a software editor, and an 8-point verification checklist. - Telemedicine platforms, patient monitoring apps, medical dashboards with predictive analytics - [Hospital e-health project costs 2026](https://www.bob-le-developpeur.com/blog/cout-projet-esante-hospitalier): Realistic budgets for hospital IT projects — DPI (500K-3M EUR), BI dashboards (80-300K EUR), patient portals (80-200K EUR), FHIR connectors (15-150K EUR).
