Senior Frontend Engineer | React · Next.js · TypeScript | AI product & real-time analytics UIs | Ex-Co-WIN / U-WIN

About

I build frontends for AI and data-heavy products. For the last three years that has mostly meant conversational interfaces and analytics dashboards: streaming AI responses token by token over WebSockets and Server-Sent Events, rendering agent logs and tool calls as they happen, and keeping large data tables fast enough to actually work with. I do this in React and Next.js with TypeScript, usually with Redux Toolkit and RTK Query underneath. Before that I spent about two years on Co-WIN and U-WIN — India's COVID-19 vaccination and universal immunisation platforms. That work taught me more about frontend engineering than anything since: eleven languages on the public portal, an interactive state-level map in D3, and a hard requirement that all of it work on low-end Android phones over unreliable connections. Constraints like that make you a better developer than a fast laptop ever will. What I tend to own on a project: the initial setup, the state and API layers, the component library, accessibility and performance, and often the Docker/Jenkins pipeline that ships it. I also design in Figma when a project needs it — I've done the design and the implementation on five products, which makes handoff conversations a lot shorter. Recent work includes an enterprise AI analytics platform I built from scratch on the Next.js App Router (60+ component design system on Radix and Tailwind, three concurrent WebSocket channels, Microsoft SSO), a multi-tenant AI analytics product for consumer brands with SSE streaming and per-client theming, and a real-time dashboard builder with drag-and-drop layouts and a custom Redux WebSocket middleware. 9+ years in total. I left Covalense in April 2026 and have been freelancing while I look for the right senior frontend role — React, Next.js, TypeScript, ideally on an AI or data-heavy product. Open to Hyderabad, Bengaluru or remote, and available to start immediately. Easiest way to reach me is kbhavanishankar94@outlook.com. 📍 Hyderabad / Bangalore
