About Me.

I am an Java Backend Engineer with a strong interest in Python, eager to contribute to real-world projects. I specialize in building reliable backend applications, designing secure APIs, and exploring efficient systems solutions.

My technical expertise spans Core Java, Spring Boot, Hibernate, SQL, and Python, combined with database setups in PostgreSQL and MySQL. Graduating with a Master of Computer Applications (MCA) in 2023, I focus on resolving complex engineering challenges—such as concurrency deadlocks, N+1 query fetching, and input latency optimization.
