About me
One dev, every hat you’ll ever need
I'm a software engineer who got tired of picking a lane. Instead of choosing between AI, data, cloud, web or apps — I just do all of them. One codebase at a time, one clean deploy at a time.
Started building in college — launched Travellio and Collabaid, learned from my mistakes, and levelled up fast. Now I work as a software engineer at a US-based startup — systems automation, data pipelines, semantic search — while parallely picking up freelance projects like Novexa Lifesciences.
Quality in less time — I optimise for shipping, not for meetings.
One dev, full stack — AI, data, cloud, web, apps, automation. You get a whole team in one person.
Startup-first — I build for founders who need momentum, not enterprise bloat.

What I do
Services that cover everything
From a single AI feature to a whole product. Pick a lane — or better, don't. I'll handle the rest.
