Harish Krishnan - Loves to Build Web

00About

Specialized in building fast, accessible web interfaces with React, TypeScript, and CMS integration. Committed to scalable architecture, user-centered design, and maintainable code..

I'm a senior frontend engineer with 8+ years specialising in modern React architecture and headless CMS systems. I build scalable, component-driven interfaces focused on performance and accessibility. I architect clean component models, optimise build pipelines, and manage confident deployments across locales and timezones.

My work spans component design in Storybook, React migrations, design system establishment, and production-grade CMS integration. I obsess over the details: pixel-perfect, accessible UI that performs at scale. I mentor teams on frontend best practices, modernise legacy systems, and take responsibility for the code I ship.
