About

Building large-scale backend platforms is the core of my work, and over ~3 years at Intuit as a Software Engineer (SWE-2), I’ve delivered high-impact systems using Java, Spring Boot, AWS, GenAI, SQL, Microservices, Distributed Systems, and multi-tenant backend architectures. My contributions span platforms serving 4M+ firms, handling 1M+ monthly GenAI-powered IVR calls, and enabling cost savings of $143M+ across product lines. Here’s a snapshot of backend work I’ve delivered: - Built backend foundations enabling appointments & video meeting services for 4M+ firms, contributing directly to 5% revenue lift. - Designed and built scalable data ingestion services, KPI calculation engines, and a taxonomy system powering workforce operations. - Engineered multi-tenant backend patterns and libraries for QuickBooks CRM externalization, helping firms onboard with minimal code changes. - Developed GenAI-powered backend assistants and IVR intelligence, influencing a 40% increase in workflow completions and reducing support load. - Consolidated 12+ AWS Lambdas into a single Spring Boot microservice and improved dev-velocity by 7%. - Handled seasonal readiness with load testing, monitoring dashboards, and security fixes to ensure high availability. Backend engineering is most impactful when it blends clean abstractions, scalable architectures, and sharp problem-solving. My competitive programming background (Expert at Codeforces, Knight at Leetcode, and 4-star at CodeChef) supports how I reason about system design, performance, and efficient backend development. Thus, over the last few years, I’ve helped improve business outcomes by at least 7x across product lines. I enjoy backend development where clean abstractions, performance tuning, and distributed-systems thinking come together to solve real production problems and long-term evolution. Therefore, as a Backend Developer / Software Engineer, I’m always interested in opportunities where engineering directly shapes reliability, latency, and user experience at scale.
