About
Hi, I'm Karan. I like software that is fast, safe and actually finished.
I'm a software engineer from Nagpur, India, with 5+ years of shipping products end to end. I led the frontend of a self-custodial crypto and NFT wallet at Zapit, researched metaverse tooling at Samsung R&D, and now build an AI-based fitness coaching app at Human Powered Health.
I started out teaching Flutter on YouTube and freelancing for studios while I was still in college. These days I also build with AI from the first prompt to a live URL: a Mac app, a planning tool, a video pipeline and a handful of browser games. Then I write down how, in plain words, on the blog.
What I do
Three things I'm good at
Mobile and web3 products
Flutter apps with clean architecture and Bloc, from client work to a self-custodial wallet where real money is on the line. I care about wallet and trading experiences that feel safe.
AI products and tooling
AI coaching at work. On my own time: agents with human review gates, local voice and transcription pipelines, and tools that remember how their user works.
Shipping end to end
Idea, design, code, tests, deploy, domain, analytics. I've written my release steps down as recipes an AI can run, so a finished project goes live in minutes.
