He has worked across a wide range of technologies over the years, including React, Node.js, Next.js, React Native, Laravel, CakePHP, C#, Perl, MSSQL, MySQL, GraphQL, and AWS, giving him a practical view of how to build software that fits real business needs.
His recent work includes building a drag-and-drop CMS for a vehicle sales platform, supporting client-specific React components, and helping deliver custom software for organisations ranging from banks to industrial clients.
