Lead Developer (contract) — State Forensic Examination Committee, Belarus (06/2026 – 08/2026)
IT infrastructure management system — built from scratch, deployed nationwide
• Designed and single-handedly built from scratch the agency’s IT infrastructure management system: architecture, database, backend and user interface.
• Deployed nationwide across the Republic of Belarus and in active use today; trained end users.
• Scale: 1,000+ users and 10,000+ tracked assets — user accounts, hardware, information systems.
Stack: Python, Django, React, TypeScript
Middle Unity Developer — Mcoon Games LLC (02/2026 – 07/2026)
Mobile game development for iOS and Android
• Developed two casual mobile games in Unity, published on Google Play: Monsters Playground and Mosaic: Jigsaw Puzzle.
• Implemented casual puzzle gameplay mechanics, designed and built the UI, integrated Unity Ads monetization, and optimized performance for mobile devices.
Stack: Unity, C#, Unity Ads
Freelance Software Developer — private clients (2021 – 2026)
• Commercial software development for private clients: full cycle from requirements to delivery.

PROJECTS
MyFinance — personal finance tracker mobile app (pet project) (2026 – present)
Sole developer: mobile client, backend, infrastructure, store release · myfinanceapp.by
• Independently built a cross-platform (iOS/Android) app for tracking income, expenses, savings goals and loans, synced through a custom REST API.
• Implemented multi-currency accounting that locks the exchange rate at transaction time, keeping historical reports accurate regardless of rate fluctuations.
• Set up subscription monetization on Google Play (monthly and annual plans, 170+ countries) and a web account portal for account and data deletion per Google Play policy.
Stack: React Native, Expo, FastAPI, PostgreSQL, Docker Compose, Linux VPS, Cloudflare
Face & Gesture Recognition System for Device Control (Computer Vision) (2026)
• Built a computer vision system that recognizes faces, body pose (skeleton) and hand gestures in real time on a laptop CPU, with support for switching between multiple cameras.
• Gestures trigger OS actions (volume, media, app launch); a command fires only when a face is detected at the same time, preventing false positives; tracks the person’s position in the room.
• Modular event → action architecture makes it applicable to access control (touchless employee entry through turnstiles) and smart home scenarios.
Stack: Python, OpenCV, MediaPipe
OnDuty — AI receptionist SaaS for small businesses (LLM, RAG) (2026 – present)
• Building a service where an LLM agent answers business customers 24/7 in Telegram using the company’s knowledge base (RAG) and books appointments itself by checking free calendar slots.
• Implemented vector search on PostgreSQL + pgvector with local embeddings and support for any OpenAI-compatible model; business dashboard for managing bookings.
Stack: Python, FastAPI, PostgreSQL + pgvector, multilingual-e5, aiogram 3, HTMX, Docker Compose
