Uchkun Rakhimov

I'm a backend engineer from Tashkent, Uzbekistan. I've been building production systems since 2021.

I started out at East Telecom, where I rewrote an old Google Apps Script Telegram bot into a Laravel service. It still runs today. After a couple of years there, I went freelance.

The freelance period was where I learned the most. I built systems end-to-end for small companies: a courier CRM, a WiFi authentication portal across 14 branch offices, a VoIP middleware for a call center.

More recently I worked remotely for Numeo.ai on their Chrome extension backend on GCP, and spent a few months at Startups DNA redesigning Fastify APIs and building notification infrastructure on Google Cloud Tasks. Most recently I was a backend developer at Carlink, a B2B auto transport platform serving the US market. I'm currently looking for my next role.
