About

I’m a Senior Java Backend Engineer with over 6 years of hands-on experience building scalable, high-performance systems in product-based environments. My core strength lies in designing and delivering robust microservices, system integrations, and reusable backend frameworks that improve developer productivity, system maintainability, and time-to-market. At MyNextHire, I’ve led critical projects involving third-party integrations with platforms like Google, Microsoft, DocuSign, Naukri, and LinkedIn. I architected a reusable OAuth2 framework that drastically reduced development effort across integrations. I’ve also mentored junior developers, enabling faster onboarding and independent contributions. One of my key wins was refactoring legacy integration code into a unified base framework—cutting dev time by 50% and improving long-term maintainability. I’m passionate about clean architecture, performance optimization, and team enablement. Whether it's designing custom Spring Boot utilities (like a custom @Required annotation for API validation) or co-creating standardized REST APIs used across 1000+ endpoints, I aim to deliver backend solutions that are elegant, efficient, and scalable. Beyond the code, I act as a bridge between engineering and business—translating complex requirements into backend deliverables, collaborating with Product and QA, and contributing to architectural planning and production stability. I’ve documented processes, onboarded developers with technical guides, and driven sprint efficiency with reusable assets. Now, I’m preparing for the next phase of my journey—taking on more tech lead responsibilities, contributing to large-scale systems, and ideally applying my backend expertise in the fintech space, where performance, reliability, and scale are critical. If you’re building something that demands scalable backend systems, clean APIs, and solid engineering culture—I’d love to connect.
