I build digital
products end to end
Websites, mobile apps, browser extensions, VPN infrastructure and AI platforms. From idea and prototype to release, documentation and support.
Websites and services
Web platforms, landing pages and internal tools that grow with the business.
Mobile apps
Android and cross-platform apps: from MVP to a product with sync.
AI solutions
Model integration, one API, spend tracking and self-hosted platforms.
Team for your project
Strengthening your team: frontend, backend, mobile development.
Products, not slide decks
Every project is taken to a state people actually use: a store listing, APK releases, a public website and open source.
Private SpeedDial: bookmarks that belong to you
Chrome extension and Android app sharing one data format: notes, folders and sync through your own cloud.
XIO: a VPN that lives on your own server
Your own VPS, your users, five transports and one interface on Android, Ubuntu and Windows.
x1o: one harness for every model
Self-hosted platform for personal AI assistants: one API, dialogue queue, billing and a cloud plane for tenants.
ECONA: kite–solar–electric catamaran
Ocean-going catamaran with kite traction, solar generation and electric drive: calculations, structure and open documentation.
Services
I take on work that needs the full cycle: architecture and interface, build, release and support.
Websites and services
Landing pages, corporate sites and internal services: React and TypeScript on the front end, Python or Node on the back end, clean APIs and integrations.
Browser extensions
Chrome Manifest V3: quick-access panels, sync, data import and export, privacy by default and Web Store publishing.
Mobile apps
Native Android in Java and Kotlin, cross-platform apps in Dart and Flutter, hybrid WebView apps with a native bridge.
Desktop and system integration
Windows apps on Avalonia and .NET, Tauri shells, Ubuntu packages, work with system drivers and services.
VPN and network infrastructure
Your own VPS: setup over SSH, Xray and WireGuard protocols, obfuscation, user management and configuration export.
AI solutions and LLM integrations
Models behind one API, dialogue queue, spend tracking, push notifications and a self-hosted platform under your control.
How the work goes
Short iterations and working builds instead of reports. You see progress every week.
Brief
We go through the task, constraints and acceptance criteria, and fix the scope of the first version.
Prototype
We build the skeleton: screens, data model, API. The idea is validated before full development.
Development
Iterations with working builds. Code, tests, reviews and clear documentation.
Support
Releases, updates, monitoring. I answer questions and fix what breaks.
Stack
I pick tools for the task, not for fashion. Everything below is used in real products.
Blog
Write-ups of my own products: how they work, which decisions were made and what did not work.
