Software Engineer | Java, Spring Boot, Kafka, Redis, MongoDB, Angular | Building scalable APIs & distributed systems @ OnGraph

About

I'm a backend software engineer with 3+ years building scalable, high-performance systems — REST APIs, event-driven architectures, and secure payment/auth flows used in production. At OnGraph Technologies, I've designed and shipped backend services processing real user and payment data at scale: integrating Stripe with secure server-side validation (cutting refund processing time by 40%), building JWT-based auth and role-based access control, and automating bulk data pipelines that cut onboarding time by 60%. I've also worked on MongoDB schema design and indexing strategies to improve query performance under load, and refactored legacy modules to async patterns for better throughput. I care about system design fundamentals — data modeling, API contracts, performance under scale, and reliability — and enjoy the problem-solving side of engineering as much as the building (500+ LeetCode problems solved). Currently exploring backend/distributed systems roles where I can go deeper on scale, architecture, and systems that hold up under real-world load.
