• Tech lead & mentoring for a small team + an English-speaking intern.
• Data governance: kSuite repositories for partners, scoped internal access, SSH keys, an online vault, password manager.
• Built an LLM code-knowledge-graph as a living memory of the codebase.

Channel-manager SaaS: a hub that turns partner CRMs into a shared pool of opportunities, with no manual client-file exchange — 50,000+ company records enriched and cross-matched across 3 different CRMs.

Delivered: everything — feasibility, design & blind spots, backend, tests & edge cases, frontend, code + no-code architecture, production.

• Pipeline: internal scan → OCR → structured JSON to a Pipedrive lambda (then N8N) → RPA data entry into the LIMS via Citrix.
• Landscape review and performance benchmark of cloud OCR providers on biology-specific semantics.
• Secure drive and anonymized PDFs for GDPR compliance (binary shredding).
• Self-hosted N8N on an o2switch VPS, headless Playwright RPA via CDP to drive the desktop LIMS software.
• Managed the transition phase end to end: study, proposals, design document, implementation, feedback loops, hosting, shipping, documentation and training.

Delivered: everything.

• Upfront Product Design (UX/UI) scoping phase to align the software with business expectations.
• Built a CRM + ERP on Bubble.
• Secure, data-sovereign file storage (kSuite Drive) and legal-document deposit via an accredited French SaaS.

• Real-time streamed transcription, handling varied voices, background noise, and foreign accents.
• Spoke at AI conferences.
• Full study, proposals, estimates, specifications, PoC and prototypes via agentic coding.

• Certified an XML/SOAP API against Enedis's SGE web service, including TLS certificate management.
• Managed the relationship with Enedis support and client follow-up.
• 14 endpoints and 54 unit tests on Make.com.
• Switched to N8N to integrate JS scripts and AI agents: index scraping + Enedis data processing.

• Feasibility study for a hybrid Windows + Linux cloud infrastructure, roadmap, costing and specifications.
• Managed disk quotas, permissions and shares; subscription plans.
• Very large file uploads without FTP.
• Converted AutoCAD files to a BJSON working format on Windows IoT.
• Built a WebGL 2D/3D web studio with web workers and scalable updating of edited working files.

Role: versatile architect.

• Mobile app where each paramedic reports availability, location, equipment and qualifications in real time.
• Request handoff between paramedics.
• Real-time backend and part of the QML / JS-signals frontend.

• Implemented a complex Figma design in no-code, with strong attention to visual detail.
• Managed the full ATS funnel, from application to qualification, with advanced UI logic tailored to the candidate's profile.
• Mass emailing via Brevo, with full deliverability configuration (DKIM, DMARC, SPF).
• WhatsApp Web deeplinking to smooth out candidate contact.
