Backend Engineer specializing in Python and Java.

I build scalable backend systems, automation tools, and developer-focused applications with a strong emphasis on clean architecture, performance, and maintainability.

My work primarily involves Flask, Spring Boot, REST APIs, PostgreSQL, Redis, and modern software engineering practices. A strong competitive programming background has shaped my approach to problem solving and performance-oriented software development.

A competitive programming platform built with a strong focus on scalability, maintainability, and real-time interactions.
