A React application to showcase some front-end ideas. This site only serves as a static information site for me. This site uses primarily self-written CSS to style it. It also uses some animations and animation libraries.

FlexiCadastre is a legacy cadastral management system with the following features:
- License management system.
- Action workflow system.
- Extensive spatial features like checking overlaps, rendering shapes into block-based data, and projecting shapes into different spatial systems.
- Very comprehensive role and access management.

FlexiCadastre uses the following technologies:
- Web Forms
- VB.NET
- C#
- JQuery
- ArcGIS
- Esri mapping
- SQL Server with Geometries

This project is a functional OpenID Connect authorization server. It is currently still in development, but I use it in personal projects for authorization and authentication. React was used for the project's front-end development and OpenIddict for authorization.

The project is fully kitted out with GitHub Actions to build up versioned image releases for consumption in Kubernetes microservices architecture projects.

I worked at IoT.nxt primarily on the Commander platform's back- and front-end sides.

The project had a well-built microservices architecture and processed an immense amount of telemetry. Its complex and dynamic front-end aspects allowed users to build great dashboards to visualize and control their IoT world.

I led the team that focused on the security of the system using the following technologies:
- gRPC
- OpenID Connect
- Identity Server 4
- Kubernetes
- .NET
- C#
- Angular/TypeScript
- Angular Material
- RabbitMQ

One of the most successful gambling and sports betting websites in South Africa and the African continent. Working on a project like this has many challenges as an immense volume of transactions needs to be processed, and issues like concurrency and throughput become relevant.

The website integrates with many third-party gaming services and financial integrations concerning vouchers, purchases, and payouts, making it a fast-paced and challenging environment.

Landfolio API is a project that provides a RESTful API to the FlexiCadastre back-office system.

In this project, I was instrumental in building and maintaining the DevOps procedures. Many shared libraries were turned into shared libraries for consumption in both the back-office system and the API project.

This API used the following technologies:
- C#
- ASP.NET Web API
- Swagger
- Docker

This project is a public replacement version of FlexiCadastre.

It aims to expose licensing, GIS, and action workflow features to the general public instead of being locked into the Landfolio back-office application.
I led this project from a technical perspective setting up the DevOps and containerization workflows for this project.

The project uses the following technologies:
- ASP.NET Core
- Angular
- Swagger
- SDKs
- Bootstrap
