About
I'm a builder at heart, focused on creating real-world systems that solve actual problems. My journey in software development is driven by a deep curiosity to understand how systems work at every layer—from the database to the user interface.
With hands-on experience across modern JavaScript frameworks like React and Next.js, as well as traditional backend technologies like PHP and Node.js, I bring a versatile approach to development. I believe in choosing the right tool for the job while maintaining clean, maintainable code.
Security is not an afterthought—it's foundational to everything I build. From implementing proper authentication with JWT and RBAC to following OWASP security guidelines, I ensure that applications are not just functional, but also secure and reliable for users.
I'm constantly exploring new technologies, contributing to projects, and learning about the latest developments in web security, performance optimization, and emerging tech like AI and blockchain.
