🔹 Migration Symfony 4.4 → 7.x on legacy application (100k+ lines, 20 days, zero regressions)

🔹 Architecture of performant REST APIs (Laravel/Symfony) for B2B clients

🔹 Setup of Docker environments for dev & CI/CD

🔹 Generation of complex PDFs, integration of third-party services

🔹 Training junior developers (best practices, testing, architecture)

Stack: Symfony, Laravel, Vue.js 2-3, Redis, Docker, MySQL, CSS/Sass

Full-stack development within a B2B SaaS startup on a Laravel 9 / Vue 2 application. Active participation in the complete cycle: design of new features, improvement of existing code, writing of unit and feature tests in the backend. Rigor imposed on PRs and code quality. Direct contact with clients to gather needs and ensure follow-up.

Technician in recombinant protein production (cell-free system), operation of 10L fermenters, analysis techniques (Western Blot, PCR/amplification).

This experience forged a methodological rigor directly transferable to development: systematic documentation of protocols, traceability of operations, zero tolerance for regression in production. It's the same logic as a CI/CD pipeline or a zero-downtime migration.

Concrete asset: I understand the vocabulary, constraints, and business challenges of laboratories and biotech players — a real advantage for any project at the interface between software and life sciences.
