With over 15 years in mobile game development, I focus on creating systems that are both scalable and maintainable. My experience spans Unity and software architecture, applying both Data-Oriented Design (ECS) and Object-Oriented Design (OOP) to solve complex challenges. I’ve contributed to large-scale projects with millions of players worldwide, always ensuring performance and stability through feature flags, safe rollouts, and thoughtful system design.

I help mobile and F2P studios fix retention and monetization. PM of C.A.T.S. by ZeptoLab — 100M+ downloads, $60M+ gross booking, Google Play Game of the Year. 20 years in games (13 in F2P), 50+ projects with EA, Microsoft Studios, Disney, Gameloft, Zeptolab, FunPlus, Yodo1, Voicemod, Xsolla and more. My thesis: games retain when they teach well. Most retention problems are teaching problems — an FTUE that doesn't teach, an economy players don't understand, progression that stops making sense. ✅ What I do: - Game & app audits: spot retention, engagement, and monetization issues; deliver a prioritized, actionable roadmap - FTUE & onboarding design - F2P monetization design (IAP, ads) and game economy - Product management: KPIs, A/B tests, soft launch, LiveOps roadmaps - Game concept creation and creative direction - Process audits, team mentoring and coaching 🏆 Recognition: BAFTA nominee, IGF finalist, GDC speaker, IGF judge, European Commission expert evaluator, features in Game Developer (Gamasutra). 💬 Client testimonials: - "One of the best game designers I have had the pleasure to work with... a magnificent blend of game design and product management." - "Skills to bring value in several areas of our studio: vision, strategy, process optimization, product management and winning tactics." Typical engagement: fixed-price diagnostic first (play, deconstruct, written findings + roadmap), then ongoing advisory if it makes sense.

Let's discuss your project and build something great together.

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
