Freelancer profile translated to English.
Back to original languageAbout Naofel
Senior Spring Boot / Angular engineer, I design and deliver solid and secure web products turnkey — and integrate AI where it creates value.
My profile is twofold: software development + cybersecurity (security engineer by training, 2x CTF winner). Security is therefore not an afterthought: it is considered from the design stage, 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 one month for ~€500 in API costs, adopted in production and rolled out company-wide.
- Designed from scratch a well performance optimizer as Lead Developer: best practices, code quality, and performance delivered to the team.
Stack: Java / Spring Boot, TypeScript / Angular, PostgreSQL, Docker, Azure, CI/CD, application security (OWASP) / AI agents.
My fixed-price method:
1. We define the scope and deliverables (included / not included).
2. Quoted price and milestones.
3. Independent development, with regular progress updates.
4. Tested, secure, documented, ready-to-deploy delivery.
Full remote, evenings and weekends + 1 day during the week. Perfect for: launching an MVP or a product, robust APIs, securing or refactoring an existing codebase.
Describe your project to me: within 48 hours, clear scope, firm price and deadline.
