At Sprinto, I cut a production dashboard query from 7.7 seconds to 0.7 and fixed a background job that had frozen for more than nine minutes. I also built an evidence review and approval workflow and configurable tools that automated compliance tasks.

At Flipkart, I designed multimodal product search across a catalog of more than 400 million products. I implemented Qdrant vector search at approximately 20 QPS and around 100 ms P99 latency, and improved RAG and semantic retrieval quality by about 15%.

At InfraMarket, I architected and scaled the Customer Central microservices platform, improving onboarding and deal-processing efficiency by 35%. Earlier, at Extramarks, I led development of a Live-Class System and contributed to the Question Management System.
