Who I am

About Me

Full Stack Developer with 3+ years of experience building scalable ERP systems, SaaS platforms, and real-time web applications using React.js, Next.js, Node.js, TypeScript, and Express.js. Skilled in designing REST APIs, RBAC systems, WebSocket-based applications, and scalable SQL/NoSQL database architectures with a strong focus on performance optimization and maintainable code.

When I'm not coding, I enjoy contributing to open source, writing tech articles, and exploring the intersection of design and engineering. I believe the best software is both technically excellent and beautiful to use.
