Struggling to get AI actually working inside your CRM, support system, or legacy platform not just a chatbot demo that never ships? I connect LLMs to real business data and workflows, backed by 7 years building production systems at fintech and foodtech companies.

Your game is stuck mid-development and the previous dev left? I rescue troubled game projects. 4 shipped titles, 6+ years in Unity and Godot, and a track record of taking over broken codebases and shipping them. I took over Hometopia — a Unity sandbox game on Steam — after the team collapsed. I rebuilt the multiplayer system from scratch, cleaned up years of tech debt, and shipped it. I also rescued Fleet Commander: Pacific mid-development after the previous programmer left, delivering a WW2 strategy game with multiplayer and AI systems. What I do: → Project rescue — take over stalled/broken codebases and ship them → Unity & Godot game development — gameplay, UI, tools, multiplayer → Mobile game development — performance-first architecture for low-end devices → Rapid prototyping — full game jam entries shipped in under 72 hours → Multiplayer networking — real-time co-op, lobbies, state sync → Custom tools & pipelines — narrative editors, level design tools, automation How I work: - Daily progress updates and playable builds - Clear milestone structure with no surprises - I ask hard questions early to save expensive changes later - Everything documented so your team isn't dependent on me I've shipped on PC, console, and mobile. I contribute to the Godot engine itself. I build tools that save teams hundreds of hours. And when a project is on fire, I'm the person you call. Let's talk about what you need shipped → blugart.dev
