Scouting report

Dominican full-stack dev with from-scratch C++ systems and security depth

assessed from open-source footprint

Staff

75signal

Full-stack developer with a disciplined, zero-abandonment record across 18 repos in TypeScript, C# and C++. The standout is a from-scratch JWT implementation in C++17 with hand-rolled Base64URL, SHA-256 and HMAC, signalling real low-level and security understanding beyond typical CRUD work; a MERN vet-clinic rounds out the full-stack side. Star counts are small, but the original systems work shows genuine technical curiosity.
