What if Y Combinator was a city?
Every company ever funded as a place you can walk. Districts are categories, building height is team size, pedestrians are real founders and they'll stop to say hi.
Some of what I've built, newest first.
What if Y Combinator was a city?
Every company ever funded as a place you can walk. Districts are categories, building height is team size, pedestrians are real founders and they'll stop to say hi.
I researched all 6,077 YC startups. I wanted to know: do these startups share anything in common? And how have trends shifted over time?
Every launched Y Combinator company, embedded by what it actually does and projected onto a single map, so neighbours build similar things. Describe your own idea and it finds the nearest ones — who they are, when YC funded them, and how many survived.
Fun weekend project. We were curious which company YC founders actually choose to work at: OpenAI or Anthropic.
The answer is a Sankey diagram.

A gym for cold calls. You call an AI prospect that talks back and stays in character the whole way through — skeptical, too busy, stalling, pushing back on every point — and difficulty runs from easy to brutal.
When you hang up, an AI coach scores the call across five sales skills, flags the moments worth reviewing, and shows you the line you should have said instead.
Cold calling, discovery, objections, negotiation, closing, gatekeepers, and voicemail practice — no roleplay partner to schedule and no one watching you fumble.

A self-improving quant researcher agent that autonomously finds new alphas and retires decayed ones over time.
Evaluation logic is deterministic in quantitative trading, which makes it easy to see whether the agent is actually improving over time.
Self-evolving systems are interesting to me because almost no human intervention is needed for the system to learn, execute, and reflect.
Built at the AI Engineer World's Fair Hackathon hosted by Cerebral Valley.

Built at AgentMail's HackHalloween. Took 1st in the Summoners track and 3rd grand prize overall.
With Oscar Hong, Alessandro Duico and Sai Krishna
Co-founded.
iOS & Android
A pre-trip inspection companion for truckers. No more fumbling with paperwork and cumbersome PTI checklist forms — one checklist at a time.
Built, shipped, and live on the App Store and Play Store in less than a week.
Open source
A tool for finding premium domains. It watches domain status continuously and pings you on Telegram (and elsewhere) the moment one frees up.
It can also hunt by length — 2- and 3-letter domains are the premium ones, so it keeps searching for those and tells you when one becomes available.
A B2C app that cuts food waste at local businesses — restaurants, cafés, and bakeries. Nearby surplus food shows up on a map, either discounted or free.
Anyone could build their own quiz and share it — especially handy for teachers assessing their students.
I wrote it in PHP at 14–15, after learning the language in a week. The code is not great and I know there are bugs and vulnerabilities in there. I'm not going to fix them; I'm busy now :((
Still, it was my first "big" project, and it took 1st place at a contest called O'quvchi yoshlar media festivali.
