What I'm looking for

I’m looking to contribute to a forward-thinking engineering team that values innovation, collaboration, and creative problem-solving—building reliable backend systems with strong system design, performance focus, and measurable impact.

I’m an Enthusiastic and detail-oriented Java Developer with nearly 3.5 years of hands-on backend experience, specializing in building scalable, maintainable systems with clean architecture and performance optimization.

At Paytm Money, I developed the complete Refer & Earn module, including gratification workflows, driving a 35% increase in user onboarding, Demat account openings, and first-trade conversions. I also built and scaled the Subscription Module—managing subscription plans, platform fees, and tariff structures for thousands of daily users.

I integrated HyperVerge automation for KYC to reduce manual review time and operational costs, and I instrumented services using Prometheus metrics and proactive alerts to improve incident response reliability. By optimizing SQL queries and Redis caching, I achieved a 40% latency reduction, and I focus on end-to-end testing, debugging, and continuous system improvements.
