I’m a game developer and systems-focused programmer with experience shipping complete projects from concept to release. I specialize in rapid prototyping, gameplay systems, single-player game design, and technical problem solving, with a strong focus on building clean, maintainable, and scalable systems. I’ve worked across many areas of development — including gameplay programming, project management, technical design, tooling, audio implementation, UI workflows, and production support — which allows me to adapt quickly and contribute wherever needed. I’m especially comfortable working with small teams, building features from the ground up, debugging difficult problems, and helping projects stay organized and moving forward. My strongest skillset is systems development: gameplay logic, state management, tools, architecture, optimization, and creating workflows that make development smoother for both developers and designers. I enjoy tackling complicated technical challenges while keeping the end-user experience intuitive and polished. Above all else, I value honest and direct communication. I believe great development work depends on clarity, responsiveness, and trust, and I make it a priority to keep clients informed, aligned, and confident throughout the entire process.

Congrats! You've just found your high-performance web developer! Need fixes or improvements on your existing project, migrating to a new platform or ready to start a new web project? I look forward to hearing from you! Shopify, Wordpress, Woocommerce, Magento, custom Web apps. Tech optimisation, SEO, integrations, digital marketing, SLA, consulting.

15+ years in IT. 200+ launched projects — most of them still running successfully in production today. I specialize in projects on fire: the previous contractor disappeared, the release is failing, the store crashes under load, or the codebase has become unmaintainable. I step in, quickly make sense of unfamiliar code, stabilize the situation, and set up a process so the crisis doesn't happen again. What I can help with: E-commerce development — PrestaShop (custom modules, migrations, customization, performance optimization), fullstack PHP Project rescue — code audits, legacy refactoring, getting development back on track after a team has vanished AI automation — integrating AI into business workflows: order processing, content, customer support, internal tools Project management — I don't just write code; I can run the project end-to-end: team, deadlines, client communication You get more than a developer — you get someone who has seen hundreds of projects and knows which solutions survive production, not just the demo. Reach out and describe your situation — even if the project seems beyond saving. Chances are, I've seen something like it before.

For the last decade I’ve worked as a Senior Mobile and Full Stack Software Engineer in Silicon Valley. Some notable experience is my work for Apple on the iOS Photos app, and my work for Coinbase on their self custody Wallet app. From small startups to fortune 500 companies, brand new projects to apps with hundreds of millions of users, I’ve worked with all kinds of teams and software. While mobile app development is my strongest skill, I have lots of experience in full stack environments with a myriad of technologies and platforms. I also have quite a bit of experience with UI/UX, 3D Modeling, and even some firmware development. And while I do have many skills, I will be upfront about any technologies in which I don’t have past experience. I work efficiently and independently and I strive to deliver a value that more than exceeds my cost to clients. I’m passionate about high quality software and I look forward to working with your team to deliver just that!
