I'm a full-stack developer based in India, and I built ToolStackHub because I kept running into the same frustration: every useful online tool either asks you to create an account, slaps a watermark on your output, or quietly uploads your data to some server you've never heard of. I wanted tools that just work — no strings attached.

My background is in web development. I work primarily with Next.js, React, TypeScript, and Tailwind CSS. I've been building on the web for years, but ToolStackHub is the project I'm most serious about — it's where I put tools I actually use myself and think other people will find genuinely helpful.

Most of my focus right now is on two verticals: Indian finance tools (salary calculators, tax regime comparisons, HRA and PPF calculators) and developer utilities (JSON formatters, text repeaters, base64 encoders, QR generators). The finance tools are particularly interesting to me because Indian tax rules change every year and most online calculators are months behind. I try to keep everything updated as soon as rules change.

The architecture principle I care about most is browser-first processing. When you use a tool on this site, your data never leaves your device. No API calls with your salary figures, no server-side processing of your invoice details. This isn't just a marketing claim — it's how the code is actually written. If you open the browser DevTools and check the network tab, you'll see what I mean.

I also write about tax, productivity, and AI tools when I find something worth documenting. The blog is an extension of the same philosophy — practical, specific, and written from actual experience using the things I'm writing about.
