Gaurav Shankar — Staff Software Engineer @ Zepto Typing intro

LinkedIn Email Blog

👋 About me

I build backend systems that stay correct under heavy load, from B2B SaaS at Freshworks to 10-minute commerce at Zepto. I started in QA, moved into backend engineering, and still design with failure modes in mind first.

🎫 500K 🤖 70%+ ✉️ 10M 🔀 400M
support tickets/day tickets auto-resolved by AI emails/day delivered events migrated live

🚀 What I'm working on

  • 🛒 Staff Engineer across Cart, Payments, and Coupons & Campaigns at Zepto, the checkout path every order goes through
  • 📡 Built Zepto's real-time, bi-directional communication platform on MQTT, backed by Scylla DB. In-app chat was the first use case, and other teams can build on the platform too.
  • 🎧 Led the 0→1 build of Zepto's in-house, multi-tenant support platform, which replaced third-party tooling and now handles ~500K tickets/day
  • 🤖 Designed an AI-first chatbot platform that product teams configure and ship on their own; it automates 70%+ of incoming tickets
  • 🔥 Own peak-day readiness: capacity planning, failure-mode analysis, and cost and performance tuning
