Hi, I'm Thanga
Senior Front-End Architect · 10+ Years Experience
I'm a Senior Front-End Architect at Accenture, where I design and lead the frontend architecture for enterprise-scale web platforms. My day-to-day involves setting architectural standards, running performance audits, and making the hard tradeoffs that keep large codebases maintainable as teams grow.
I started this blog because I kept seeing the same mistakes repeated — not because developers were careless, but because the hard lessons from production systems rarely get written down. Every post here comes from something I've actually built, broken, or debugged at work.
What I Work On
Frontend Architecture
Designed component systems and micro-frontend architectures used by thousands of users. Deep experience in React 18+, Next.js App Router, and TypeScript at scale.
Performance Engineering
Achieved sub-second LCP on production apps serving millions of page views. Tools of choice: Lighthouse CI, WebPageTest, and Chrome DevTools profiling.
Developer Tooling
Built custom ESLint rules, Webpack plugins, and internal CLI tools to enforce architectural boundaries across large monorepos with 50+ engineers.
Engineering Leadership
Led technical reviews, mentored junior developers, and defined coding standards and architecture guidelines for cross-functional teams.
My Stack
About TechSheet
TechSheet covers frontend architecture, React patterns, web performance, and the practical side of AI tooling for developers — topics I write about because they come up in code reviews and architecture discussions every week.
The name comes from cheat sheets — dense, high-signal references. That's the standard I hold every post to: if you can get the same information faster elsewhere, I haven't done my job.
