Gentlemen: Business Strategy
Unity Developer → Team Lead
A business strategy game built around production, progression, and managing a growing operation.
My contribution
- 15 → 60 FPS, −70% crashes in about a month (Honor 70): rebuilt the game into independently loaded modules that scale down as the player progresses, fixed memory leaks and rewrote hot algorithms.
- GOAP + sensor AI for up to 100 employees: agents can be killed, arrested or hospitalized and resume exactly where they stopped; multi-role agents never deadlock.
- Team Lead of 4 Unity developers and 3 QA — hired every one of them, ran sprints and mentoring.
- AI in the studio: a GBrain knowledge base from Slack, chats and Confluence, an AI teammate in Slack, and release notes generated from commits.
- Ad monetization (ironSource → AppLovin MAX) — ads became a revenue source for the first time; quests, progression, pricing, offers and onboarding.
PRODUCTION. PROGRESSION. PERFORMANCE.
World War Armies
Unity Developer · 10M+ downloads
A multiplayer real-time strategy game with unit-based combat and tactical decision-making.
My contribution
- Started the game solo and grew it with the team to release.
- Moved all gameplay to Photon Quantum (deterministic rollback) while it was still in beta; scaled matches from 1v1 to 4 players.
- Built bot AI inside the Quantum simulation.
- Technical game design: unit stats, damage and range formulas, combat balance.

VR platform
for education
Unity Developer · product role
Joined at the start and shaped the architecture, gamification and features of a VR platform — Varwin Education reached 100+ Russian schools by 2020. Solved multiplayer for objects that know nothing about each other with a fast reflection layer that networks user-authored logic; shared Photon sessions for up to eight users.

shooting simulator
Senior Lead Developer
Led the team and moved a legacy codebase to a modern architecture. Built animal AI for boar and moose hunts — animals hear a shot, panic and flee — and networked shooting for two shooters in different locations on one range, with synchronized targets and ballistics. Delivered to the customer.

Unity Developer
A survival shelter sim in the vein of Fallout Shelter, with unique heroes on top of regular residents. Worked on the major “Era of Heroes” update — heroes, combat, quests, daily rewards, UI — and built shared C# combat logic with server-side battle validation. The project was closed in 2022.
Heroes at War
Unity Developer
A browser and mobile strategy with ~1M registered players. Supported the live game while building its successor — delivered ~40% of the new project: UI and gameplay in C#, with PHP / Haxe / SQL on the server.

Developer / Game Designer
A colony survival sim with autonomous NPCs: headless .NET server + Unity URP client. ~240k lines of C# and ~1,900 automated tests, built AI-assisted under my architecture and review.
- Game AI. Colonists perceive, score goals and plan multi-step actions; a built-in detector explains why an NPC got stuck. LLM agents drive characters through MCP with validated commands.
- Netcode. Clients regenerate the world from the seed instead of downloading it; delta snapshots cut traffic 202 → 10 KB/s per viewer, event filtering 3,571×.
- Engineering. Simulation runs ~200× real time headless; golden-trace regression tests and CI gates. FMOD with baked lip-sync, RU/EN.
- Agent pipeline. An orchestrator runs 5–6 coding agents through my own tracker, Flashback; every build lists the bugs it contains.
