I am a Backend Engineer at POP with 3+ years of professional software engineering experience, focused on building scalable and reliable backend systems. My core expertise includes Golang, PostgreSQL, REST APIs, system design, Docker, and Kubernetes. I enjoy solving complex engineering problems, designing efficient backend architectures, and building services that are reliable, maintainable, and performant. I started my career in frontend development before transitioning into backend engineering, giving me an end-to-end understanding of how products are designed and built. This experience helps me collaborate effectively across engineering, product, and frontend teams. I’m also passionate about Data Structures & Algorithms and competitive programming, and have participated in competitions such as Google Kick Start and Meta Hacker Cup. Currently, I’m focused on deepening my expertise in backend engineering, system design, databases, and scalable infrastructure.
