Intensity Labs 1/4

Six years of turning ideas into software people use. I work out what to build, build it, and test it until it holds up. AI helps me move fast; I still own every line. These are my business cards. Pick them up, throw them around, flip one over.Click one to flip it over.

Things I build for fun

Two Telegram bots that people use every month, and three small tools I built to scratch my own itch. Flip a card for the details, or try each one on the work page.

About

Behind the desk

I'm Darvesh, Technical Product Lead at Intensity Labs, working remotely. I joined in 2025 to build the backend and run QA, and now I lead product as well.

Before that I spent three years at ElevateHQ on the software that works out what salespeople get paid, going from developer to senior developer along the way. Before that, I built backends for financial services at Shapeman.

Outside work I run a few Telegram bots that hundreds of people use each month, and I write down anything that took me too long to figure out. Away from the keyboard: life, and travel.
