I build Unity applications across architecture, engineering and construction (AEC), games, mobile apps, simulations and real-time 3D.
I have worked in software engineering since 2005 and with Unity and C# since 2012. As a Certified Unity Expert Programmer, I take projects from technical planning through architecture, development, optimisation and deployment across WebGL, iOS, Android and desktop.
My work spans Unity development, gameplay systems, 3D pipelines, native mobile integrations, backend APIs, multiplayer, cloud infrastructure and CI/CD.
AEC, CONSTRUCTION AND REAL-TIME 3D
I create Unity solutions for architecture, engineering and construction, including:
• Interactive building, home and product configurators
• Real-time architectural visualisation
• Parametric modelling and design automation
• SketchUp extensions using Ruby and the SketchUp Ruby API
• Automated geometry, metadata and GLTF export pipelines
• Runtime GLTF and GLB model loading in Unity
• GIS and geospatial 3D visualisation
I develop custom SketchUp extensions that inspect model structures, extract geometry and metadata, apply project rules, generate configurable variants and export Unity-ready assets.
In Unity, I build runtime systems for materials, colours, dimensions, component options, pricing, camera controls, saved configurations and backend integrations.
GAMES, APPS AND SIMULATIONS
My experience includes commercial mobile games, PC and console titles, location-based apps, educational software, training simulations, multiplayer systems and virtual environments.
I can assist with:
• Unity gameplay and application development
• Mobile, desktop, console and WebGL delivery
• Educational and training simulations
• Location-based and augmented reality applications
• Multiplayer and server-authoritative systems
• Unity UI and editor tools
• Performance, memory and app-size optimisation
• Native iOS and Android plugins
• Unity upgrades, technical audits and complex debugging
• App Store, Google Play and TestFlight releases
GIS, FULL-STACK DEVELOPMENT AND DEVOPS
I have delivered mapping applications using Unity with Mapbox, WRLD and Google Maps, and Angular applications using Leaflet, HERE Maps and Esri ArcGIS. Use cases include architectural visualisation, indoor navigation, asset tracking, drone simulation and GeoJSON processing.
For backend and web development, I work with Node.js, Express, TypeScript, PHP, Firebase, MongoDB, AWS, Azure and Google Cloud. I build APIs, authentication, admin tools, content pipelines, analytics integrations and real-time services.
I create automated pipelines using GitHub Actions, GitLab CI/CD and Fastlane for Unity builds, mobile signing, WebGL deployment and release management.
AI-NATIVE SOFTWARE DEVELOPMENT
I use Claude, OpenAI Codex and MCP-based tooling for codebase analysis, prototyping, implementation, testing, documentation and maintenance.
My AI-assisted workflow combines clear specifications, experienced architectural direction, source control, code review, automated testing and CI/CD validation. I also help teams adopt AI-native workflows through agent-ready documentation, reusable skills, coding standards, test-driven development and automated reviews.
SELECTED PROJECTS
• Woodoku Blast — Tripledot Studios: Technical Lead for two years on a commercial mobile puzzle game with millions of users. I led architecture, gameplay systems, native iOS and Android integrations, performance, technical direction and CI/CD.
• Block Gun 3D series: Lead Multiplayer Developer using Photon Unity Networking on mobile games with several million monthly active users.
• WeStretch: Principal Software Engineer on a commercial Unity fitness app for iOS and Android. My work included architecture, Firebase and Node.js services, native integrations, subscriptions, offline support, performance, app-size reduction, Unity upgrades, and CI/CD. I also established engineering standards and guided long-term technical direction.
HOW I WORK
I can lead a complete technical workstream or join an established team to solve a defined problem. I contribute as a senior Unity engineer, technical lead, solution architect, full-stack developer or consultant.
As the founder of multiple companies, I understand the commercial realities behind software decisions. Clients value my ability to understand the goal, identify risks early, communicate options clearly and turn complex requirements into maintainable software.
CREDENTIALS
• Certified Unity Expert Programmer
• More than 20 years of software engineering experience
• Unity and C# development since 2012
• Certified Scrum Master
• Certified DevOps Engineer
If you need an experienced Unity developer or technical lead for an AEC platform, game, app, simulation or real-time 3D product, send me a message.

Most Product Managers manage a roadmap from the outside. I've spent 15 years on the inside — actually building the iOS and Android products that PMs typically only spec and track. That background changes how I do this job: I don't ask my engineering team if something's feasible, I already know. I don't pad timelines because I'm guessing at complexity — I've built the thing myself, more than once.
I made the transition from hands-on mobile development into product management because I kept ending up owning the "why" and "what" as much as the "how" — prioritizing features, negotiating scope with stakeholders, and making the tradeoff calls that actually shape whether a product succeeds. Now I do that work full-time, with the technical fluency most PMs have to hire someone else to provide.
WHAT I DO:
• Product roadmap development & feature prioritization
• MVP scoping and validation for early-stage products
• App monetization strategy — ad mediation (AdMob, AppLovin MAX), in-app purchases, subscriptions
• Sprint planning, backlog grooming, and agile delivery coordination
• Writing technical specs and PRDs that engineers can act on without back-and-forth
• Stakeholder communication — translating business goals into engineering priorities and vice versa
• AI-assisted development workflows to speed up iteration and reduce engineering overhead
WHAT I USE:
• Jira, Confluence, Linear, Notion, Slack, Teams
• Figma (for reviewing and iterating on UI/UX with design)
• Firebase Analytics, Mixpanel, Amplitude
• Claude Code and AI-assisted engineering workflows
HOW I WORK:
I operate well in fast-moving, high-ambiguity environments — the kind where priorities shift weekly and "we'll figure it out as we go" is the actual plan. I default to clear, frequent communication over big-batch updates, and I'd rather flag a risk early than surprise you with it later.
WHY THIS BACKGROUND MATTERS FOR YOU:
If you're a startup building your first app, I can help you scope an MVP that's actually buildable in your timeline and budget. If you're an established team looking to grow revenue, I understand the monetization mechanics well enough to make real optimization calls, not just recommend "run more A/B tests."
