Collection DNS, IP, domain, and network tools. Inspired by mxtoolbox and started as a side project, but the collection will keep growing.

I like building tools nobody thinks about until they need them.
Indie Developer, early-stage investor, and co-founder of Chakkiwale — a mill-cum-retail store for freshly milled flour, spices, and oil. Most of what I build is backed by open-source libraries, some I write and maintain.
Some of the things I've built
Web Apps
A bidirectional Morse Code translator with live translation, audio playback, and signal visualization—designed to make learning and practicing Morse code simple and engaging. Built out of my own curiosity, this tool goes beyond basic translation to help you go from beginner to confident user.
Converts HEIC images (the format iPhones shoot in) to all possible image formats. Conversion from HEIC to target formats happens in the browser — no uploads, no server processing, and no limit.
Webapp to compress different file types (images, videos, documents, etc.) — just the thing you need when a file is too large and you want it smaller without uploading files to server.
Other Ventures

Background
I grew up in Nainital, a hill town in Uttarakhand. Did my schooling there, moved to Chennai for a B.Tech in Computer Science at Dr. MGR Educational and Research Institute, then to Bangalore for an M.Tech at IIIT Bangalore. I've been here since, which is a polite way of saying I got stuck in Bangalore traffic and never left.
I spend most of my time building small, single-purpose web apps — network tools, image converters, file compressors, browser based games, and game solvers. The kind of thing you Google once, use for few minutes, and move on. Boring problems, but I like making them work well.
I also invest in very early-stage startups, supporting founders at the earliest stages of their journey.
Outside of code
I grew up around mountains, so flat landscapes never really do it for me. Most weekends, I’m trying to escape the city—chasing highways, hill stations, wherever the road leads. India has some incredible drives, especially if you don’t mind crawling behind a truck at 20 km/h on a hairpin bend.
I’m equally drawn to beaches. If I want to look within, I head to the mountains. If I want to get lost, I head to the sea.
I travel the way I build tools — pick a destination, figure out the minimum viable plan, and deal with whatever happens along the way. Most of my best trips have had zero planning and at least one moment where I had no idea where I was.
I don’t live in the hills anymore, but I haven’t really left either.
Now
Working on a few Mac app ideas aimed at improving everyday productivity, alongside my current web apps and open-source library projects.
