IT Lead Profile
Computer Science Engineer graduated from Polytech Nancy (IA2R). My background combines solid full-stack engineering expertise (Spring Boot microservices, React/Angular, .NET Core) and secure cloud infrastructure (Kubernetes, CI/CD pipelines) with critical embedded IoT/OT systems (LIN/CAN automotive gateways, real-time physical buses, FreeRTOS). Versatile and adaptable, I bridge business requirements with highly available, resilient, and secure distributed architectures.
Professional Experience
- HDS Environment & Compliance: Developing critical software solutions within an HDS (Health Data Hosting) certified ecosystem, ensuring sensitive data protection and strict compliance with GDPR standards.
- Microservices & Cloud Architecture: Designing and maintaining highly resilient distributed microservices using Spring Boot, orchestrated via Kubernetes (K8s/Docker) and securing asynchronous flows via RabbitMQ.
- DevOps & Critical Tasks: Full automation of CI/CD pipelines under Jenkins and developing automated background CRON jobs for processing and reconciling heavy data under PostgreSQL.
- Security & Alcohol Compliance: Designed a custom interception gateway running in the DOM event-capturing phase (`useCapture = true`) to halt checkout actions, ensuring 100% legal compliance in Luxembourg.
- Performance & Zero CLS (Lighthouse 100): Comprehensive optimization of the static rendering architecture (Liquid/CSS), achieving a 100/100 Lighthouse Performance score and zero Cumulative Layout Shift (CLS) on mobile devices.
- IntersectionObserver & Web Component: Developed a historical countdown component optimized for mobile CPU cycles using IntersectionObserver and synchronized at a constant 60 FPS using requestAnimationFrame.
Architecture & R&D Projects
Physical MITM gateway on Tesla Model 3 LIN-bus, restoring physical stalks and intercepting steering capacitive commands to inject CAN-bus macros via diagnostic port. Coupled via BLE to a React Native real-time HUD dashboard.
Situation: Real-time processing obligation on the LIN-bus within a strict deterministic delay of 1.5ms, under penalty of haptic communication errors.
Action: Isolation of the safety-critical LIN capture task on Core 1 of the ESP32 using FreeRTOS C++, offloading CAN calculations and BLE telemetry to Core 2.
Result: Latency of sub-1.5ms deterministic execution, total stability (0 frame errors), and fluid telemetry.
Recruitment agent based on decoupled RAG in a Git submodule. Semantic search by cosine distance in a PostgreSQL database, coupled with an analytical observability portal.
Situation: Avoid 429 rate limit errors from free LLM quotas during simultaneous user access sessions.
Action: Conception of a fallback infrastructure with 5 priority levels, paired with a quota exclusion cookie at midnight and a Redis cache. Native PostgreSQL vector computation via PL/pgSQL RPC under 10ms.
Result: 100% availability, first token under 150ms, and analytical dashboard secured under JWT.
