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.

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." Let's talk about what you're building.

Most clients come to me after a bad experience with someone else. A developer who went silent mid-project. An agency that delivered something that looked nothing like the brief. A freelancer who could write code but couldn't think about the product. I've heard all of it, and it's part of why I built my practice the way I did. Over 7 years, I've worked with startups trying to launch their first product, mid-size companies scaling fast, and enterprise clients who needed things done right the first time. The budgets were different. The industries were different. But every single client needed the same thing: someone who actually gives a damn about what they're building. That's what I bring. 📱 Mobile — Flutter for iOS & Android I've shipped 15+ Flutter apps across healthcare, fintech, eCommerce, SaaS, on-demand services, and social platforms. From concept to App Store approval, I manage the whole thing, clean architecture, smooth animations, Firebase, in-app purchases, push notifications, secure auth, and full lifecycle management. Not demos. Not prototypes. Real apps with real users. ✔ Cross-platform Flutter apps for iOS and Android ✔ AI-powered mobile apps with OpenAI and LLM integration ✔ Real-time apps — chat, live tracking, collaborative tools ✔ eCommerce and marketplace apps with payment integration ✔ On-demand, booking, and service apps ✔ SaaS mobile apps with subscription and billing flows ✔ Startup MVPs built to scale from day one 🤖 AI-Powered Mobile Apps This is where most Flutter developers stop. I don't. I've integrated AI into real client mobile products, not experiments. That includes conversational AI chatbots built into mobile UX, smart recommendation engines, OpenAI and custom LLM API integration, image recognition features, and AI-powered automation inside production apps. If you're thinking about adding AI to your mobile product and aren't sure where to start that's exactly the kind of conversation I'm good at. ⚙️ Tech Stack Mobile: Flutter · Dart · iOS · Android · Firebase · Supabase · App Store · Play Store Backend for mobile: Node.js · Python (FastAPI) · REST APIs · GraphQL Databases: Firebase Firestore · PostgreSQL · SQLite · Supabase Cloud: AWS · Google Cloud · Docker · CI/CD Payments: Stripe · PayPal · Apple Pay · Google Pay · In-App Purchases AI: OpenAI API · LangChain · LLM integration 🏆 The Honest Version of My Track Record ✅ 7+ years shipping mobile products not just coding them ✅ 15+ Flutter apps live on App Store and Play Store ✅ AI features integrated into real client apps, not just experiments ✅ Fixed broken codebases, scaled slow apps, launched MVPs from zero ✅ Clients from USA, UAE, Australia, Europe and beyond ✅ I think like a business owner.
