## About
- Name: Anton Tkachenko (handle: anttka4)

## How it works
AI handles the repetitive groundwork in hours; a decade of development judgment handles design, feel, dread, and polish. The result is automation speed with veteran craft — a finished game, delivered sooner and cheaper. Raw AI output is never shipped.

## AI harness & models
I don't rely on a single model — I run a harness that routes each task to the model best suited to it, cross-checks outputs between models and against the spec, and gates everything on my own review:
- Claude (Anthropic) — reasoning & design: architecture, gameplay logic, code review, and design documents. The judgment calls that need structure and taste.
- Codex (OpenAI) — implementation: fast, agentic coding that turns an agreed spec into working systems and iterates at machine speed.
- Gemini (Google) — research & multimodal: long-context work, sifting references, and reviewing art and screenshots.
The harness routes every task to the right model, runs drafts in parallel, cross-checks the results, then stops at a human gate. Nothing ships without my review — AI accelerates the work; I make the calls.

## Services
- Game Design Document (GDD) — 2–4 days. Professional spec: core mechanics and game loop, scope and full feature list, level/flow outline, engine and build plan.
- Prototype Sprint — 1–2 weeks. Playable proof of the core mechanic, one representative level, atmosphere and basic audio pass, desktop or browser build, full source included.
- Full Small Game — 4–6 weeks. Complete, polished, shippable title: multiple levels, menus, audio, UI, tested build, full source and all rights.
- Larger projects, ongoing work, or rescuing an unfinished game: an honest, no-obligation quote on request.

No public price list — every project is unique and is scoped and quoted individually — clear terms agreed in writing before any work starts, flexible as the project evolves. No open-ended hourly billing. Premium solo development — the value is senior judgment at AI speed, not the lowest bid.

## Who he works with
- Founders & creators — custom games built from scratch, start to finish.
- Studios & teams — contract development, overflow capacity, or bringing an AI-accelerated pipeline into an existing production (NDA-friendly).
- Businesses & brands — promo games, gamified marketing, playable experiences.
- Fellow developers — rescuing, finishing, and polishing half-done projects.

## Verified track record (checkable on itch.io)
- Catched In Fire — built inside Trijam #348's 3-hour limit; placed #4 in Visuals and #6 in Theme of 22 entries.
- Dig The Sands — #34 in Gameplay/Fun of 95 entries at Chili Code Jam #3; complete puzzle game built in one week.
- 11 games self-published; 10 public game jams entered — nine ranked on itch.io (Trijam, Godot Wild Jam, Mini Gim, Chili Code Jam, and more) plus Global Game Jam '26 (self-reported).
