Hey, I'm Tushar 👋

Lead Frontend Developer building interfaces people actually enjoy using

📍 Delhi, India  ·  Open to Lead / Senior Frontend roles



🌤️ A little about me

I care about the same things a good designer does — clarity, consistency, and how something feels to use — but I build it. 5+ years turning tight deadlines into fast, accessible, secure frontends: RBAC-gated dashboards, digital-signature workflows, and consumer apps used by thousands every day.

🧵 A few things I've built

Secure Digital-Signature Workflow

Users kept dropping off mid-way through slow, confusing signing flows. Rebuilt it in React + TS with RBAC-gated views, SHA-512-backed signatures, and a step-by-step flow that felt lighter. 100% security audit pass, noticeably fewer drop-offs.

Enterprise Dashboard

A legacy dashboard that took 5–6 seconds to load with real data. Rebuilt data-fetching with TanStack Query, virtualized 1M+ rows, cut unnecessary re-renders. 40–50% faster in production, for 2,000+ daily users.

API-Driven Integrations

Frontend breaking every time a backend contract quietly changed. Owned the API layer myself — 40+ REST integrations, typed clients, JWT auth, retry logic. Fewer bugs, smoother handoff between teams.
