Summary
👤
Senior🎓
Top SchoolPierre-nicolas Tollitte is a pragmatic CTO and founder with 14 years of experience building durable, production-grade products—from a dating app serving 25k daily users to SaaS tools processing 100M+ data points. He combines hands-on full-stack engineering (React Native, Python/FastAPI, MongoDB, GCP) with leadership of small teams and end-to-end ownership of architecture, CI/CD, testing, and migrations without downtime. A former PhD researcher in formal methods, he brings rigor to system design and testing—evident in practices like 100% test coverage and load-tested critical flows. Currently he’s proving out AI-augmented engineering workflows by orchestrating supervised and autonomous agents to run an app factory and ship features solo. Based in Paris, he’s available as a fractional or full-time CTO and favors durable simplicity over hype.
