GCAbout Gabriel
Senior backend engineer specializing in regulated crypto-custody and fintech. Currently at Bitpanda, building an institutional crypto-custody platform for banks (Fastify, GraphQL, TypeScript, AWS serverless & microservices): I owned the customer crypto address-book end-to-end and hardened authentication across services.
Backend generalist underneath — Node.js, NestJS, TypeScript, AWS, PostgreSQL, MongoDB. Before Bitpanda: ImmoScout24 Austria (search & listing in a fully tested distributed system) and RWE Germany (Java→NestJS migration; ~65% faster APIs; export cut 45→12 min with worker pools). Security-first, test-driven, ships end-to-end.
EU citizen (Romania), own company / EU invoicing, remote — available for B2B contract engagements.
