About Me
I'm a backend engineer passionate about building software that stays reliable under real production workloads. My work ranges from GraphQL APIs and enterprise platforms to authentication systems, deployment automation, and real-time infrastructure.
Throughout my professional experience, I've taken ownership of complete backend systems, from database design and API development to Linux server deployment with Nginx, SSL, Docker, and production environments.
Recently I've been focusing on Rust and modern payment orchestration, exploring high-performance systems programming, asynchronous architectures, and open-source infrastructure.
I enjoy building software that's clean, scalable, secure, and maintainable rather than simply making things work.
