Backend Engineer | API & Integration Systems | Performance Optimization

Backend engineer focused on building reliable API systems, third-party integrations, and scalable backend services.

Currently working on backend infrastructure for Geojit Financial Services, where I build and maintain financial service APIs and integration layers between internal systems and external financial platforms.

Previously worked as a backend engineer at Reeltor where I helped build scalable backend services supporting 20K+ property listings and optimized system performance with caching and real-time communication systems.

I enjoy solving performance bottlenecks, designing clean backend architectures, and building systems that remain stable under real production workloads.
