Gekko Group is looking for an experienced Senior Full Stack Developer to help modernise our in-house software platforms and consolidate our legacy systems into a single, cloud-based application. This is a hands-on full-stack role covering the complete technology stack, from database and backend development through to the Angular user interface.
You will be the sole developer for the migration of existing SQL Server databases and legacy ASP.NET applications to a modern architecture built around a cloud-hosted MySQL database, .NET Core APIs and a single Angular web application. Working closely with our Lead Architect, you will analyse existing systems and business processes, plan and deliver migrations, and ensure that established functionality is transferred accurately into the new platform. This requires someone who can work confidently across the full stack, understand complex legacy systems and make sound technical decisions while maintaining business continuity.
This is an opportunity to play a key role in a significant modernisation programme, helping create a more consistent, maintainable and scalable foundation for Gekko's future software development. We are an award-winning field marketing agency connecting leading leisure, lifestyle and technology brands with consumers across retail, online and B2B channels. Our in-house software platforms play an important role in supporting our operations, reporting and delivery of services to our clients.
