01 / About
Who I Am
I'm a Full-Stack Web Developer with strong foundations in data structures, algorithms, and scalable system design.
I build production-ready backend systems in Go and Java, and modern frontend applications using React and Angular.
I enjoy working across the stack — from database schema design and REST API architecture to responsive UI implementation.
My focus is on performance, clean architecture, and building real-world applications that scale.
