Backend-focused engineer with hands-on production experience designing and maintaining RESTful and GraphQL APIs in Node.js/Express, and modeling data across relational (PostgreSQL) and NoSQL (MongoDB, Redis) databases. Built services handling authentication, rate limiting, and multi-tenant data isolation at scale, with attention to query performance and data integrity. Comfortable owning backend features end-to-end – from schema design through production – in fast-moving, early-stage environments. Experienced with TypeScript, Git-based collaborative workflows, and CI/CD pipelines (GitHub Actions). Founder of an AI-native platform (Crezumic) where I designed and maintained the full backend and database layer solo. Currently working concurrently as a Generative AI Engineer and Machine Learning Engineer.
