FranceWhat I'm looking for
I am a senior technology leader and consultant with over 11 years building production-grade data analysis platforms and AI solutions. I specialize in LLM orchestration and transforming complex manual workflows into automated, agentic systems.
At RedStrings I architected a self-learning multi-agent platform using OpenAI's API and designed Human-in-the-Loop RLHF mechanisms to fine-tune models for niche financial data, significantly improving accuracy.
I have full-stack experience implementing backend services in Python (Flask), frontend interfaces in React/TypeScript, high-performance Postgres schemas and Neo4j graph structures, and multi-regional cloud architectures leveraging AWS Lambda and Kubernetes.
I recruit and lead remote engineering teams, establish code standards and CI/CD pipelines, and deliver measurable impact—such as reducing client reporting time from eight hours to under one—while maintaining regulatory fidelity.
