Backend Engineer with more than 5 years of experience building scalable, secure, and high-performance systems. Specialized in the Node.js/TypeScript ecosystem, relational databases (MariaDB/PostgreSQL), and serverless/cloud-native architecture.
I have a strong security-first mindset with focus on both offensive and defensive application security, applied cryptography, and protection against common threats. Currently deepening my knowledge in distributed systems, zero-trust architecture, and Rust for high-performance and security-critical components.
Passionate about turning complex ideas into robust, production-ready solutions with strong emphasis on maintainability, observability, and security by design.
