Message

At PineLabs, I built an event-driven reporting platform supporting 50+ report types and processing millions of transactions a day. Apache Pinot and Redis caching reduced report query latency by 60%.

I also built a merchant assistant for transactions, settlements, refunds, POS operations, and payment queries. Its MCP-based orchestration connects LLMs to APIs across 10+ microservices, serving 1M+ users and reducing manual support effort by 40–50%.

At CaaStle Inc., I developed the Borrow system to integrate with platforms including Shopify and BigCommerce, and built a Custom Collection Service for 1,000+ tenant websites. I also developed a Style Audit Service to batch-audit styles and track machine-learning metrics.

Earlier, as a Software Engineer Intern at CaaStle Inc., I implemented REST APIs and migrated Oozie jobs from Hue CDP to EMR. My work spans Java, Spring Boot, distributed systems, and AI solutions.
