About Tarun Ahirwar

Full-stack developer in the JavaScript ecosystem: React, TypeScript and Node.js, with 4.4 years shipping production software. Enterprise SaaS is the core, data-heavy platforms built end to end from PostgreSQL and Node APIs to fast, typed React interfaces.

Frontend architecture on long-lived codebases is the specialism: component systems, application state in Redux and Redux Toolkit, routing, validation and access layers, and render performance on large datasets. Most of that work modernizes established applications rather than greenfield.

AI runs through both the product and the toolchain: LLM-powered features integrated from the application side, speech-to-text and generation pipelines behind review-and-sign interfaces, and daily engineering on a maintained agentic harness of coding agents, MCP servers and scoped subagents, with design and review kept human.

Four projects designed and built end to end, live on their own domains, in Astro, Preact and Cloudflare Workers. WCAG and ARIA conformance, keyboard paths, focus management and Core Web Vitals are build constraints on all of them, not a final pass.
