I'm a Full Stack Developer and Software Engineer with solid experience designing, building, and maintaining scalable, maintainable, and high-performance systems.

I work across the entire stack — from frontend user experiences to backend services, APIs, and system architecture. I have a strong focus on clean architecture, SOLID principles, design patterns, performance, and long-term maintainability.

I primarily work in Linux environments, using Vim / Neovim as my main editor, with an emphasis on productivity, automation, and developer experience.
