My clients range from global corporations to personal projects & startups. The impact that I deliver for clients and where my skillset is most valuable is at the intersection of AI, development and your business objectives.

I worked as a database administrator and software engineer for the government, and in the online retail industry. I feel that my strengths are in communicating with clients to understand their needs and help them to nail down the requirements for their project, and in creating cleanly architectured systems which are painless to operate and maintain. I specialise in developing back-end systems and full-stack web-applications, and have independently developed tools used for purposes such as data integration, finance, CRM and reporting/analysis. I also have considerable experience working with databases, big-data and cloud systems. Additionally, I have worked for many years on video games and Android applications, acquiring experience in computer graphics and mobile application development.

    As CTO at CodeLeap, I lead the technical side of things — turning early ideas into real, working products. I’ve spent the last few years helping startups and growing businesses build mobile and web apps that are not just solid and scalable, but actually make a difference to the people using them. At CodeLeap, we like to keep things straightforward. We work closely with our clients to figure out the right approach for each project — from choosing the tech stack to shaping how everything will come together. We’ve built everything from lean MVPs to fully featured platforms, with AI Integrations— helping clients add smart features, automate repetitive tasks, and stay ahead in their industries. We move fast, but we don’t cut corners. Good communication and clear thinking are at the heart of how we work. And while every project is different, our goal is always the same: build something that works well now, and is ready to grow with you in the future. If you’re working on a new product — or looking to improve an existing one — we’d love to chat and see how we can help!
