About Louis
Proven Expert in Mission-Critical Infrastructure With over 6 years of experience, I specialize in architecting low-latency, auto-scaling distributed systems for industries where performance is non-negotiable. My background combines rigorous academic engineering from Arts & Métiers ParisTech with hands-on leadership as a multi-time CTO and Co-Founder.
Why Work With Me?
Scalability at Core: I have built and maintained systems serving 30M+ monthly active users, processing over 100,000 concurrent notifications with sub-second latency.
Full-Stack Strategy: As a former CTO, I bridge the gap between business objectives and technical execution, from ETL/Spark pipelines to robust React Native deployments.
Fintech Precision: My recent work includes engineering high-frequency API layers for financial data platforms (FastAPI/AWS ECS), focusing on sentiment analysis and institutional fund analytics.
AI-Ready Architectures: I develop integration layers like MCP servers, enabling LLMs to query complex databases via natural language.
Core Technical Stack:
- Backend: Python (Asyncio/FastAPI), Node.js/TypeScript.
- Data & Infrastructure: AWS (ECS/Lambda), GCP, Spark, Airflow, Snowflake, Redis, and SQL/NoSQL.
- Leadership: CTO-as-a-Service, technical strategy, and architectural auditing.
