Become a sponsor to Justin Walsh

I am Justin Walsh: a former game-studio CTO, full-stack engineer, game developer, and open source builder with 15+ years shipping interactive software across games, web, mobile, creative tools, and app-store ecosystems.

I help teams get games and graphics-heavy apps to market: review-ready builds, better performance, cleaner architecture, sharper workflows, higher quality, and fewer expensive mistakes between prototype and launch.

Why I am worth sponsoring

• Former CTO-level operator: I have led technical direction inside a game studio, made product and engineering tradeoffs under real constraints, and helped teams move from ideas to shipped software.
• Shipping experience: I have spent years building games, apps, UI systems, creative tools, native extensions, and web/mobile products where performance, polish, and delivery all matter.
• Game launch and app-store readiness: I know how to get games and apps through review, raise performance and quality, debug release blockers, and turn vague platform requirements into practical engineering steps.
• Performance and architecture leverage: I can look at a codebase, workflow, or product direction and tell teams where the real bottlenecks are: technical, organizational, or both.
• Modern workflow advantage: I actively use AI coding tools, local agents, and automation to make engineering work faster without letting quality disappear into the machinery.

What I build in public

• three-flatland: my flagship creative-dev project, focused on composable 2D tooling for modern Three.js scenes.
• middle: my local agentic developer-workflow project, exploring how coding changes when agents become real collaborators.
• ts-defold: a TypeScript-first toolchain and ecosystem I created for Defold developers.
• Open source contributions: value added to other people’s projects and ecosystems, including a recent three.js bug fix, pixi.js/Pixi ecosystem work, React and React Three Fiber tooling, Adobe UXP React/types/template work, a React concurrent store ponyfill, and practical fixes, bindings, examples, and glue code across creative-dev and game-dev spaces.

What sponsors get

At the lower tiers, sponsorship helps fund the public work: AI subscriptions, infrastructure, CI, hosting, internet, devices, examples, maintenance, and focused time to keep useful open source moving.

At the higher tiers, sponsorship buys leverage: help getting games and graphics-heavy products to market, senior technical judgment, architecture review, performance triage, app-store delivery guidance, workflow design, technical demos, talks, workshops, and strategic engineering support from someone who has shipped under pressure.

If you are a founder, studio, product team, or engineering leader, the value is simple: I help you move faster, avoid expensive mistakes, and turn hard technical ambiguity into a plan your team can execute.

What your sponsorship funds

• Continued development of three-flatland, middle, ts-defold, and modern creative-coding tools around Three.js, React, and React Three Fiber.
• Focused maintenance and documentation for game-dev tooling across Defold, Godot, TypeScript, C/C++, and graphics-heavy web apps.
• Practical upstream contributions, bug fixes, examples, and interoperability work in the ecosystems I use and care about.
• The very real subscription stack behind modern open source work: AI coding tools, research assistants, CI, hosting, and the services that help turn limited time into better output.
• Time for demos, talks, technical writing, experiments, and the kind of deep practical research that makes teams and tools sharper.

Sponsor me if you want more of this work to exist, or if you want direct access to the experience behind it.
