Description

Expert in Hexagonal Architecture, DDD, Software Craftsmanship, and AI

I help companies modernize, structure, and accelerate their web projects. My conviction: quality and productivity are complementary. When applied correctly, hexagonal architecture, DDD, and TDD do not burden development; they reduce regressions and allow for faster delivery. I work on legacy codebases to restore their value and empower teams.

⚙️ My Expertise

Back-end: PHP 8+, Symfony 6+, API Platform
Front-end: React, TypeScript, Next.js
Architecture: Hexagonal, DDD, CQRS / Event Sourcing
Craft Practices: TDD, Clean Code, Refactoring, Code Review, Pair Programming
CI/CD & Cloud: Docker, GitHub Actions, AWS / GCP
AI & Productivity: AI agents (Claude Code, ChatGPT, Copilot), AIDD approach, and team training

💥 What I Solve

Migration and progressive refactoring of legacy projects without production disruption
Technical debt hindering delivery
Lack of alignment between business and code
Teams in difficulty: coaching and mentoring
Efficient and secure integration of AI into the development workflow

🧠 My Philosophy

Code sustainability is an acceleration lever: well-architected software evolves faster. AI, used intelligently, multiplies efficiency without replacing technical mastery.

🎓 What I Bring

Tech Lead Vision: scoping, roadmap, pragmatic decisions
Legacy Expertise: decoupling, incremental refactoring, conservative migrations
Knowledge Transfer: training and workshops on DDD, hexagonal architecture, craft practices, and AIDD

REAL ESTATE
September 2024 - Today (1 year and 10 months)
Toulouse, France
As a freelance PHP/Symfony backend developer for SAFTI, I am responsible for designing and developing new features while resolving bugs in the Omega platform provided to the SAFTI network representatives.

In addition, SAFTI's priority is to migrate this legacy system to a modern Symfony environment, adopting a hexagonal architecture and Domain-Driven Design (DDD) principles.

This migration represents a complex technical challenge, where hexagonal architecture allows for structuring code for greater modularity, testability, and scalability, and where DDD promotes design aligned with the business domain. Within this framework, I also adopt clean code best practices and test-driven development (TDD) to ensure high-quality, easily maintainable code.

This requires the progressive integration of a scalable and performant architecture while preserving the stability of the current system.

When I joined ITrust, the company was experiencing rapid growth and its SIEM/XDR product needed to scale industrially.
I led a multidisciplinary R&D team of 8 people to develop the Reveelium behavioral detection engine.
We completely refactored the architecture, moving from a monolith to microservices, and implemented ML algorithms for real-time anomaly detection.
The result: a product capable of processing 100,000 logs per second and monitoring over 1 million IP addresses in production, directly contributing to the company's valuation and its acquisition by Iliad (Free Pro).
