Back to original languageAbout Naofel
Senior full-stack engineer (top of my class at Polytech), I design and deliver robust and secure web products turnkey — and integrate AI where it adds value.
My profile is dual: development + cybersecurity (security engineer by training, 2x CTF winner). Security is therefore not an afterthought: it's considered from the design phase, at every level.
What also sets me apart: production-ready code that lasts (Hexagonal Architecture & DDD), not a disposable prototype. You get a product that you can evolve without rewriting everything.
Achievements (at TotalEnergies):
- PANDA — autonomous AI orchestrator designed by myself: 70 tickets processed in a month for ~€500 in API costs, adopted in production and generalized across the company.
- Complete refactoring to Hexagonal Architecture of a performance optimizer as Lead Developer: bugs reduced, performance and code quality significantly improved.
Stack: Java / Spring Boot, Quarkus, Angular, TypeScript, PostgreSQL, Docker, Azure, CI/CD, application security (OWASP) / AI agents.
My fixed-price method:
1. Define the scope and deliverables (included / not included).
2. Quoted price and phased schedule, firm price.
3. Independent development, with regular progress updates.
4. Tested, secure, documented, deployment-ready delivery.
Fully remote, evenings and weekends. Perfect for: launching an MVP or an AI product, robust APIs, securing or refactoring an existing codebase.
Describe your project to me: within 48 hours, clear scope, firm price, and deadline.
