About
I’m a backend and product-focused software engineer based in Paris, with hands-on experience building production systems at a Paris startup and at Airbus Defence and Space. I’ve shipped end-to-end features across Go/TypeScript/React backends and frontends, PostgreSQL, and the Docker/Kubernetes infrastructure that makes them run reliably in production.
Most recently, I’ve been building LLM-agent infrastructure on Temporal, including a Claude-driven multi-turn sales assistant with a typed tool catalogue, MCP server/gateway integration, and observability for per-tool-call metrics and conversation audit. I enjoy designing resilient agent workflows, instrumenting products from spec to release, and self-hosting the infrastructure that supports my ongoing experimentation with local LLM inference.

Work experience· 4 roles
Built a Claude-driven, multi-turn in-app sales assistant backed by a typed async tool catalogue for prospecting, research, and CRM enrichment. Designed a sub-agent delegation layer running in isolated context windows in parallel to address transcript growth and Temporal’s 2 MB payload limit. Implemented an MCP server and an mcp-gateway microservice to expose platform capabilities to the assistant and third-party assistants (Claude/ChatGPT). Added observability with per-tool-call metrics and conversation-audit tooling, owned features from spec to release, and integrated PostHog funnels. Stack included Go, Echo, Temporal, PostgreSQL, React, TypeScript, MCP, Anthropic API, Docker, Kubernetes, Helm, and AWS ECS.
Contributed to the CSOAR (Cyber Security Orchestration, Automation & Response) product by refactoring Java/JAX-RS modules, fixing defects, and adding JUnit tests under SonarQube quality gates. Worked in a security-focused environment where reliability, test coverage, and code quality were emphasized.
Built a secure-coding cyberrange lab to teach secure coding practices to developer students alongside CS department and IRIAF Master’s students. Developed and operated the lab platform using PHP/MySQL, combining practical exercises with educational guidance for learners.
