The whole product, not a single layer
Fullstack development and design: mobile apps, web, Telegram bots, backend and infrastructure. I take a product from brief to release, so you do not have to assemble a row of contractors and keep them in sync.

What I do
Every line here is backed by at least one project in this portfolio.
Marketplaces with money
- Escrow: holding payment and releasing it after the job
- Platform commission and an in-app wallet
- Free-slot computation and booking
- Two-sided platforms with a partner cabinet
Payments
- Card acquiring with holds and payouts
- Subscriptions and recurring charges
- Cryptocurrency and messenger currency
- Local gateways for foreign markets
AI in the product
- AI as an input method: a dialogue instead of a form
- Vector search by meaning rather than words
- An assistant answering from a procedure
- A chat persona in the author's voice
Backend and infrastructure
- Self-hosted platform: schema, row-level security, triggers, edge functions
- An own Python API with a background job queue
- Go agents managing servers
- VPS deployment: web server, systemd, backups
- Monitoring, error tracking, tests
Maps and geo
- Routes with waypoints
- Distance search and marker clustering
- Coordinates in safety scenarios
Telegram
- Bots and mini apps
- Payments inside the messenger
- A mini app working as the product checkout
Web and admin panels
- Next.js with a CMS and an own database
- Admin panels for moderation and partner management
- PWA as a product's third platform
Design
- I work with a designer, so layouts arrive finished instead of being invented during markup
- Simpler interfaces and fixes I draw myself, without waiting on a contractor
- Markup driven by Figma design tokens, not by screenshots of a mockup
How the work goes
No surprises halfway through.
- 1
We break the task down and decide what the first version actually needs and what can wait
- 2
Timeline and budget before the start; decisions are written down
- 3
Development with running builds you can try, not progress reports
- 4
Release, infrastructure and handover of credentials are on me as well
Tell me about your project
I will tell you how long it takes and what it costs before any work starts. If it is not my kind of task, I will say so right away and point you elsewhere if I can.
