At Certa, I rebuilt Studio’s WebGL canvas as one of two core engineers, keeping customers’ largest workflows interactive at 1M+ nodes. I designed a React-style renderer using Pixi.js and Yoga.
I also invented a rule language and browser parser that moved rule authoring from engineering to customers’ power users; patent applications were filed in India and the US. Its Lexical and Chevrotain editor includes context-aware IntelliSense and live validation, and lets the config team ship screening rules without engineering help.
For Certa’s Hermes project, I built an integration and workflow automation product from scratch, including a visual DAG editor, templates, and webhook and cron triggers. After launch, clients went live within a month, and the config team integrated external APIs independently.
At Certa, I built Watchtower, an AI on-call agent that investigates Sentry crashes, writes a failing test, and opens a fix PR for review. Previously, at Bajaj Finserv Health, I moved doctor search to server-side rendering, increasing bookings by 25%, and built a tele-consultation suite in React and TypeScript.
