About Me
I’m a Software Engineer with over 9 years of experience in backend development using Java and modern web technologies. Recently, I’ve expanded my skill set to include Next.js, TypeScript, and React, allowing me to build end-to-end applications with scalable architectures and clean, maintainable code."
My background includes hands-on experience with AWS, API design, and system optimization — skills that enable me to bridge backend reliability with a smooth frontend user experience. I’m passionate about writing efficient code, learning continuously, and delivering real business value through technology.
I’m currently open for remote work opportunities with US-based teams, especially those looking for engineers who thrive in fast-paced environments and take ownership of complex technical challenges.
