I’m a founding engineer at MrMed, an Indian online pharmacy for specialty medicines. I architected and shipped its Next.js storefront, admin and operations platforms, which serve 100,000+ concurrent users. I also helped design the NestJS and MongoDB backend behind checkout, payments and shipments.

I care about performance and reliability in production. I cut p75 LCP from 4.2s to 1.6s, and I helped the platform get through a multi-wave DDoS attack with zero downtime. I also built a customer support chatbot on AWS Bedrock with RAG, which cut token usage by about 79%.

Before MrMed, I co-founded Bili Consultancy and led delivery on 50+ client projects. I also built and scaled IncogApp, which Google and MeitY’s Appscale Academy named one of India’s top 100 startups.

I work across the whole stack, from frontend performance to backend systems, infrastructure and applied AI. I’m looking for roles where I can own product engineering end to end.
