Rockstar🎓
Top SchoolJean-françois Simon is a seasoned CTO and startup builder with 15 years of experience delivering high-performance, scalable web platforms and real-time architectures. Based in Bordeaux, he combines hands‑on backend expertise—demonstrated by contributions to core Symfony components like http-kernel, console, and http-foundation—with strategic leadership as a serial co-founder and fractional CTO. He specializes in rapid MVP delivery, building and training bespoke engineering teams, and solving heavy data-volume and NLP challenges for product-market fit. His work spans full-stack product launches, fintech for good (MarkInvest.), and production-grade optimizations such as cache, memory, and security improvements in widely used open-source libraries. Known for moving quickly without sacrificing quality, he often leverages a trusted network of freelancers to accelerate time-to-market while retaining long-term technical ownership. An atypical strength: deep familiarity with Symfony internals paired with a pragmatic shift to event-driven, JS-heavy stacks when it best serves the product.
