About

The engineer
behind the code

Full-stack developer with strong expertise in designing scalable and maintainable software architectures across multiple technology stacks. I seamlessly manage both front-end applications and back-end services, from REST APIs to real-time systems. Self-driven and detail-oriented, I bring hands-on experience administering cloud infrastructure, managing databases and containerization, while delivering pragmatic and creative technical solutions.
