ABOUT ME
Professional Summary
Founder & Principal Engineer of Zone4Build — an AI application platform with a production-grade browser IDE and a governed, multi-tenant backend, so enterprises get AI-speed delivery without losing control or ownership.
Développeur Full Stack Senior with 10+ years of experience designing and delivering complex enterprise systems across biometrics, telecom, identity management, and SaaS platforms. Proven track record in microservices architecture, cloud infrastructure (AWS, Kubernetes), and secure authentication systems (Keycloak, mTLS). Deep expertise in Java SpringBoot, React/Next.js, Angular, and multi-database strategies (PostgreSQL, Couchbase, Elasticsearch, MongoDB).
I am particularly drawn to environments where engineering rigour meets product impact — where the systems built have real consequences for the people and organisations that rely on them. Most recently I have focused on bringing large language models into software delivery — building AI agents that write and ship production code under human governance, not hype. I thrive in collaborative, technically ambitious teams and am equally comfortable leading architecture decisions as I am writing production code.

- Plateforme d'Applications IA: Designed and built a platform that turns natural-language descriptions into production-ready web applications on a managed backend, with a guided AI build lifecycle.
- Production-Grade Browser IDE: Engineered a full in-browser development environment — live preview, visual click-to-edit, integrated AI assistance, code editor and version snapshots — a real IDE built for shipping and maintaining apps, not a sandbox toy.
- Enterprise Value: Lets teams adopt AI-assisted development without losing control — role-based access, approval workflows, per-customer data isolation and auditability — so apps are standardized, governed and maintainable instead of throwaway prototypes.
- Multi-Tenant SaaS: Architected secure per-customer isolation (identity, data and runtime) with automated end-to-end onboarding — no manual provisioning.
- Cloud-Native Backend: Microservices backend with container orchestration, isolated per-project runtimes, automated deployments and TLS throughout.
- AI Agents: LLM agent system with guarded tool execution and human-in-the-loop approvals for safe, reviewable automation.
- Managed Backend & SDK: Automated data, authentication and access provisioning, exposed through a reusable SDK for seamless integration.
- Billing & Access: Subscription billing, SSO and role-based access across customer accounts.
