Himanshu Nagar

I’m a full-stack engineer with 4.5 years of experience, including 3+ years as a founding team engineer and tech lead at a funded B2B SaaS startup. I’ve built core product, infrastructure, and data systems from zero to production.

At Attryb Tech, I designed and built the full-stack MVP (React, Node.js, PostgreSQL, AWS) as the sole engineer, then grew and led a team of 5+ engineers. I established code review standards, participated in hiring, and set technical direction.

I engineered a real-time personalization engine that delivered segment-targeted on-site experiences, converting personalized traffic at 2%+ CR and driving 20Cr+ in attributed GMV across merchant stores. I also architected and owned a real-time event analytics platform ingesting clickstream, session, order, and visitor journey data to surface segment insights, location analytics, and historical event data.

To optimize performance and costs, I self-hosted RudderStack to reduce data pipeline costs by an estimated ~80% and enabled real-time event streaming into a DataLake. I replaced manual deployments with a fully automated CI/CD pipeline (GitHub Actions), built a real-time Personalisation Visualiser, and integrated Stripe and Shopify Billing APIs for subscription lifecycle management and metered billing logic.
