Back to original languageAbout Ayoub
Do you have a prototype running on Cursor, Bolt, or Claude, but it's buckling under technical debt? Want to integrate AI into an existing system without rebuilding everything? Are you taking your B2B SaaS from POC to production? That's where I come in.
AI Engineer & Senior Full Stack Developer with 13 years of experience, I combine the rigor of a senior engineer with a specialization in AI Engineering: LLM, RAG, multi-model pipelines, prompt engineering, AI safety.
🔧 What I do concretely:
- Audit & Recovery: Taking over vibe-coded projects, cleaning up TypeScript debt, stabilizing Next.js, industrializing B2B SaaS.
- Advanced AI Architecture: RAG pipelines with grounding, vector databases (pgvector), AI guardrails (anti-hallucination, factual verification), multi-model orchestration (OpenAI, Anthropic, Mistral, Gemini).
- Full Stack Development: Next.js / Strict TypeScript / PostgreSQL, REST APIs, auth (NextAuth/Auth.js), GitHub Actions CI/CD, Vercel / VPS / Docker deployment.
- Technical Lead: Team mentoring, code reviews, establishing quality standards, skill development.
🎯 Ideal for:
- Taking over struggling AI projects or those with technical debt
- Industrializing B2B SaaS with a core AI component
- Integrating LLM into existing products
- Structuring missions of 3 to 6 months, in a technical lead or support role
🤝 Who I work with: VSEs, SMEs, startups, and project owners in Loire-Atlantique and remotely. Former trainer (Wild Code School, OpenClassrooms, 75+ learners trained on modern JavaScript and web architecture).
💡 My commitment:
Deliver a reliable, maintainable, and scalable product, not a prototype that will last 3 months.
I work with complete transparency (code reviews, continuous documentation, weekly check-ins) and formalize all relationships with clear contracts (Terms of Service, scope, deliverables).
