At Core Computer Business (Pty) Ltd, I developed and maintained two enterprise business applications supporting up to 2,500 employees across 82 branches and stores. I worked with business stakeholders to gather requirements, design relational data structures, and integrate internal and third-party APIs.

As a FileMaker Graduate at Core Peripherals (Pty) Ltd, I developed business application functionality involving database design, scripting, user interfaces, security, and reporting. I delivered changes through iterative development, testing, sprint reviews, and stakeholder feedback.

I also developed a training management platform backend using C# and ASP.NET Core. The project included JWT authentication, SQL Server data structures, automated tests, GitHub Actions CI/CD pipelines, Docker containerization, and Azure deployment.
