About

Backend engineer with a strong focus on building scalable systems and reliable infrastructure. Over the past few years, I’ve played a key role in Bigbasket’s journey as it transitioned from a traditional e-grocery platform to a full quick commerce business. As a lead engineer, I translated evolving business needs into robust backend solutions—owning core catalog services and driving system-wide changes that kept pace with the company’s growth. I’ve led high-impact projects across microservice architecture, infra modernization, and performance tuning—scaling systems to ~15K RPS, reducing API response times by 70%, and improving Catalog system reliability across its dark stores. I enjoy solving complex system design problems, mentoring engineers, and making backend systems faster, leaner, and more resilient.

Migrated Bigbasket’s catalog-related code modules from a monolith to microservices, creating several high-throughput APIs that power the product description pages.
These APIs handle traffic upwards of 5000 RPS with a P99 latency of approximately 200ms.
Have been the owner of the catalog microservice since its inception, continuously optimizing and scaling the flows as needed.
Have designed and owned a critical microservice responsible for ingesting and serving data related to Bigbasket’s fulfillment center (FC) assortments.
Translated high-level technical requirements into detailed specs and built the production-ready service from scratch.
This service currently powers FC catalog operations at Bigbasket, and I have been the single point of contact (SPOC) for it ever since.
