Top SchoolS G is a Senior Software Engineer based in the Greater Paris area with 11 years of experience blending backend development and applied cybersecurity. Currently at GitGuardian, he has advanced production-grade secrets detection tooling—contributing robustness, network-error handling, and smarter scan request headers to the widely used ggshield project. Trained as an engineer in cybersecurity (CY Tech/EISTI) and with research experience in anomaly detection from a stint in Japan, he brings both theoretical rigor and pragmatic engineering. His background includes homomorphic encryption security audits and hands-on backend roles across startups, showing comfort from low-level security checks to scalable platform features. Colleagues value his focus on reliability under adverse conditions (preventing aborted scans and graceful update checks) as much as his ability to ship.
