Full-Stack Developer · React · Python · PHP · APIs · Docker · Databases · Testing · AI-Assisted Software Development
I build and maintain real-world software — from REST APIs and database design to responsive frontends, mobile apps, containerized deployments and AI-assisted workflows.
I'm an active open-source contributor to OpenIMIS, the open-source health-financing & social-protection platform:
- 201 pull requests submitted across the organization — 129 merged — spanning 32 modules of the platform
- Created the Ledger frontend module from scratch (
openimis-fe-ledger_js) - Maintained the French translations module (
openimis-fe-language_fr_js) - Contributions cover the whole stack: React/JavaScript frontend modules, Python/Django + GraphQL backends, Android apps (Java), and the Docker distribution (
openimis-dist_dkr)
→ My merged pull requests on GitHub
I currently work as a full-stack developer in Cameroon on proprietary products (private GitLab repositories). The following figures are directly verifiable from the Git history and merge requests I authored:
| Product | Scope | Verified contributions (author: me) |
|---|---|---|
| MI Platform — mobile invoicing & payment platform (Symfony + React/Vite/Inertia, Docker, Jenkins) | 2026-04 → now | 45 merge requests (33 merged) · 16 commits — Vite/Inertia migration (login, reset-password, register-prospect, layouts, DataGrid, Searcher), reusable query-service architecture, PHPStan/PHPCS security hardening, invoice business logic, E2E & unit tests. |
| FlowNote — AI document platform (FastAPI, arq, S3, React) | 2026-08 → now | 4 merge requests (2 merged) · 8 commits — RAG backend migration: ingestion & reading pipelines on the arq queue, S3 handling, HMAC-signed callbacks, spec & task kit. |
Both repositories are private, so these links require access — the MR lists are the proof: MI merge requests · FlowNote merge requests
