- Running build-in-public sprints to grow my own apps.
- Pushing my English toward B2 - and starting to learn German for the EU move.

TeachTrack
A SaaS for private tutors - scheduling, lesson-package invoicing, and a Telegram reminder bot. Live, with a public metrics dashboard. ~25 people use it.
TripTrack
“Strava for cars.” I’d never written Swift - I built the iOS app (iPhone, iPad, watchOS) and a NestJS backend in evenings. Live on the App Store, ~50 people use it.
LifeTrack
A minimalist habit tracker. Native SwiftUI on iOS, React Native on Android - on both stores. ~5 daily users, no revenue yet, and that’s fine.
Fraggram
A marketplace built entirely on Telegram Stars payments - backend, bot, infra, all done. Then three payment processors refused the model, so I killed it before launch. Learned more from that than from any tutorial.
onezee.dev
This site. Open-source Astro + React, containerized and shipped to Kubernetes via Helm, werf and GitHub Actions - with a blog fed straight from Telegram.
The day job
2021 - 2026
iMe - a crypto/fintech Telegram super-app
My day job for five years. I joined as an intern and grew into a senior engineer who owns core systems. A few of the things I built:
- A high-load API gateway - one entry point for iOS, Android and Desktop, with autoscaling, multi-tier rate limiting and a sharded Redis layer.
- A subscription & payments platform across 8+ providers - App Store, Google Play, Stripe, Telegram Stars, YooKassa, Binance Pay.
- A self-custodial wallet across 9+ blockchains (Bitcoin, EVM, Solana, TON, Tron) with DEX/swap aggregation and on-chain scanning.
- An AI Telegram assistant on OpenAI with token-streaming replies.
- The unglamorous glue that keeps it correct under load: transactional outbox, circuit breakers, durable messaging - all Kubernetes-native.
