What I'm looking for

I'm looking to build scalable, high-quality web and backend systems with cross-functional teams, contributing to architecture, real-time features, and AI-powered application capabilities.

I build scalable web applications across TypeScript, Next.js, React, Java, .NET, and GraphQL. At Entelect on Nedbank, I design C#/.NET services and GraphQL APIs that support complex frontend workflows.

At Virtual Days, I led Next.js application development using the App Router and SSR, improving performance by 35%. I implemented MSAL authentication, Apollo Client data fetching, Redux state management, and Tailwind CSS to improve security, responsiveness, and UI delivery.

I enjoy owning data contracts across frontend and backend systems, from strongly typed GraphQL schemas to PostgreSQL and MySQL performance. I've also mentored junior developers, contributed to architecture decisions, and worked with containerized .NET services in Kubernetes environments.
