I am developing Koltyx, a French SaaS automation platform designed to optimize the processes of consultants and coaches. With a focus on confidentiality and sovereignty, the platform is hosted on the infrastructure of a French provider (OVH Cloud) and only uses AI models from MistralAI. A beta version will be available at the end of April 2026 (koltyx.com).

Stack:

- Full-stack microservices architecture (Spring Boot, FastAPI, React, PostgreSQL)

- Implementation of an advanced RAG pipeline: hierarchical chunking, embeddings, hybrid search (cosine + BM25 + RRF)

- Development of AI agents with function calling and tool orchestration (Notion, Slack, Google, email)

- Setup of asynchronous workers (RabbitMQ) and real-time streaming (SSE)

- Management of a multi-tenant system (RBAC, workspaces) with OAuth integrations

- Deployment of infrastructure with Docker and Kubernetes.

For almost 2 years, I have been working as a freelance web developer. I have had the opportunity to design and develop several showcase websites and web applications, assisting my clients in creating tailor-made solutions adapted to their needs. In January 2026, I joined the Malt platform to expand my professional network and formalize my services as an independent.
