I build servers, APIs, queues and the glue to physical devices. When needed, I ship the interface too.

GET

/whoami

01 / 05

I build the part users never see: where the payment clears, the device answers and the bot never sleeps.

Most of my work orbits Django: DRF, async views, WebSockets with Channels, background jobs with Celery. I integrate payment providers, drive vending machines, kiosks and heaters over MQTT, and keep a fleet of Telegram bots running in production.

I'm at home on the front end too: merchant dashboards and CRM panels in Vue 3, control panels in React, landing pages in Next.js. So I design APIs through the eyes of whoever consumes them.

GET/projects/useful-taxiUseful Taxi CRMCRM + bot ecosystem

A CRM for a taxi fleet: drivers, balances, payments and Yandex Fleet sync. The driver bot never touches the CRM database directly, only an internal REST API.

  • 4 languages: Uzbek, Russian, English, Karakalpak
