// About Me

About Me

I’m a Software & Systems Engineer focused on designing and building full-stack web systems. My work emphasizes clarity, performance, and long-term maintainability through thoughtful system design.

My approach is systems-first rather than technology-first. I think in terms of system design, API boundaries, modular architecture, and maintainable structure. Technologies are implementation details; design principles define the system.

I actively study software architecture and system design practices, including API design, Clean Architecture principles, Agile Methodologies, and more. I complement this with technical literature to deepen my understanding of how scalable systems are structured and evolved.
