What I build

Cross-platform by architecture: every system is a web interface in any browser, a Telegram Mini App on the phone, and a server under your control.

A business that fits in your phone

I turn complex businesses into a business in your phone: the rental fleet, the club, the trading desk and the house on this page already live that way. An online store with a delivery service and payment processing, accounting, orders and staff — one app that opens from Telegram.

Accounting the owner can see through

Accounting systems are built transparent at both levels: the owner sees the whole picture and every single entry, at any moment. An immutable history of operations, a document behind every figure, a ledger instead of a monthly report. It runs on a phone and takes no training to pick up.

Crypto: projects and payments

I work with crypto projects of any complexity and wire crypto payments into anything, any way you need: a store, a bot, a website, an internal system. A crypto payment layer is already built into my backend, and the trading platform on this page talks to crypto exchanges directly.

AI agents and complex structures

I wire AI agents of any complexity into working structures: my own systems are built by a staff of agents with distinct roles, and Service-Health exists precisely to command such a fleet. A business dashboard with every service connected — social media to banks. Software can take over a role end to end: it works around the clock and never resigns. Bring the task nobody has taken on.

Analytics and simulation

Analytical apps with visualisation and animation; simulation of real processes — production, logistics, finance. For example: how long a 50,000-ton barge takes to load at a given elevator throughput and truck queue. I come from international grain logistics — the model starts from the real process.

Hardware and firmware

Software for your devices, down to firmware level, over open protocols — from VIA/QMK keyboards to Modbus and MikroTik. GPS tracking with vehicle routes already runs in the rental-fleet system.

Farms and automation

I automate greenhouses, growboxes and farms — mining farms included: sensors, climate, power, telemetry and alerts in your phone, the same sensors-to-logic-to-phone chain that runs the smart home.

Demos and hosting on my infrastructure

For demos and testing the project lives on my servers: you look at a working system by link, deploying nothing on your side — which is why the demo never waits for your hardware. Then, if you choose: hosting, domains, TLS certificates and monitoring taken over entirely, with data mirrored to a backup server every night — and you can take everything in-house at any moment.

Care for family

A medication tracker for your parents — the schedule is built from a photo of the package. An alarm button for an elderly relative: one press alerts the family instantly.

Smart home

A smart home — with no intrusion into the wiring and no complex breakers hard-wired into the house's power system, on well-known brand devices; a flexible system that learns in real time; touch kiosks throughout the house; integration with every system of the home — solar panels, networks, AI video surveillance that will record and recognise even the smallest details you ask for.

Games and private servers

A game of your own design — or a private server of a favourite one for your crew.

Deepfake technology

I work with deepfake technology: altering appearance, voice, and other biometrics — for commercial projects and call interpreters.

I take on work for the defence sector, for medicine and clinics, and for industrial plants and factories: accounting, scheduling, telemetry, sensors and industrial protocols.

Backend and APIs

  • FastAPI, SQLAlchemy, PostgreSQL / SQLite
  • REST APIs and webhooks
  • Professional database work: schema design, no-downtime migrations, real backups
  • Payments: Telegram Stars, crypto
  • Schedulers and task queues

Telegram products

  • Bots on aiogram 3
  • Mini Apps with single Telegram sign-in
  • Admin panels inside the bot
  • Group assistants with memory

Web and interfaces

  • Single-page apps without a build step
  • React + TypeScript where it earns its place
  • Light and dark themes, phone-first layout
  • Kiosk dashboards for wall screens

Servers and operations

  • Linux, Docker, systemd
  • Caddy and nginx
  • Deploy, monitoring, watchdogs with auto-restart
  • Network design and upkeep: routing, Wi-Fi, segmentation, remote access
  • Additive migrations, no downtime

Integrations

  • Exchanges: Binance, Bybit, OKX, Deribit — ccxt and native APIs
  • Media and metadata: TMDB, DLNA, torrent stack
  • Smart home: Modbus TCP, MikroTik, climate and TV APIs
  • Retries and delivery logs on every channel

AI in the product

  • Anthropic and OpenAI APIs
  • Assistants with memory, roles and vision
  • Document and receipt recognition from a photo
  • Agent pipelines that build and test software

How it works

I build internal systems: accounting, fleet, CRM, Telegram apps, payment and marketplace integrations. Each one is shaped around the way your team already works.

  1. A 30-minute call: your process and where it slows down. Free.
  2. A written scope with a fixed price. You decide with the numbers in front of you.
  3. A working build in 1–3 weeks, then iterations you can click through.
  4. Delivery and a proper handover. Ongoing care is a separate contract — your call.

Inside is the same discipline a product team runs on: automated tests before every release, additive migrations with no downtime, and backups built into every system — nightly dumps, rotation, a copy on a second server. The code is light: an inexpensive VPS is enough — those 16 services run on two servers. Systems report their own failures: a watchdog with auto-restart, health endpoints and alerts surface a problem before a human would notice. The system ships running on your real data; the first weeks after launch are part of delivery. I write code so that any engineer can read and maintain it without me: a clear structure, documentation and comments that explain why — part of the delivery, not a favour. Who runs the system next stays your choice.

If I misjudge the scope, I finish the work at my own cost.

Who you are dealing with

Behind the alias is an engineer with an entrepreneur's background: about seven years of running my own business — trade, international logistics, finance and operations. I read your task the way an owner does: you are buying lower risk and speed, and features that add neither get crossed out of the estimate. My metric is the client's revenue — reputation in this craft is built on nothing else. And I like building things that outlive the contract. Choosing to work with me, you get a fair deal with a decent partner: your project gets full responsibility and understanding. One of my jobs is to actually hear the client — the idea, the fine intent behind it, if there is one.

Identity is disclosed on the first video call — under NDA, before any payment: you see my face, learn my name, and we sign the contract. The same NDA covers your project data.

Do you sign an NDA?
Yes, before any project details change hands.
How do you price?
Fixed price against a written scope; a monthly retainer for ongoing work.
How long does a project take?
An audit runs 1–2 days, an integration 2–5 days, a full system 1–3 weeks.
Where does the system run?
Your server, or mine for a demo or ongoing hosting — your choice.
What happens after delivery?
Your choice: ongoing care with me, or a handover to your own engineer.

Describe the task

Two lines is enough — the rest we sort out on the call.

What happens next

1. I reply within 2 hours with 2–3 questions.

2. A free 30-minute call: your process and the edges of the task.

3. You get a written scope and a fixed price. Then you decide.
