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.

Transforming innovative ideas into Embedded software solutions on real hardware. As a seasoned Embedded software Engineer, I specialize in developing robust firmware and software solutions for microcontroller-based systems. With a strong foundation in C/C++, RTOS and hardware interfacing, I deliver efficient and reliable embedded applications tailored to client needs. I specialize in embedded software for machines, devices, toys, experimental jigs and real-world control systems. I build the brains inside smart devices, EV chargers, IoT platforms, and mission-critical control systems. I'm passionate about delivering firmware that’s robust, efficient, and working. I've always been an employee and decided to add some spicy projects to my portfolio, so I'm happy to help other people out and contribute from my experience. What sets me apart is a rare blend of technical expertise and practical systems thinking. I understand how bits and volts play together, and I thrive when bridging hardware and software, so... hit me up with ideas and requests. I'm here for you. My expertise includes (but not limited to) the following: - Embedded software development C/C++/micro-Python/Python - Efficient low-level device-drivers, interfaces and layered application code - Threads, Synchronization, Interrupt handling, state-machines, memory management and more - Microcontrollers: STM32, ESP32, EFR32BG, NXP LPC, S32Kx, Xilinx, PIC, MSP430, 8051. - (RT)OS: ThreadX, FreeRTOS, CMX, Embedded Linux, Micrium µC, Zephyr, bare-metal. - Communication: BLE, WIFI, ETH, CAN, SPI, I2C, I2S, UART, USB, MQTT, RS232, RS485 - Peripherals: RTC, TIMER, DMA, ADC, DAC, PWM - IDE: VS Code, STM32CubeIDE, STM32CubeMX, Eclipse. - Git: Advanced level - you may ask to receive the entire development process, rather than just the latest snapshot of code at no additional cost.
