An eCommerce platform allowing clients to set up their own online shop.

I built the automated deployment process using Kubernetes to instantly create a new shop when a client signs up. I also created the front end where clients can sign-up, which would trigger background jobs to create a new instance of the shop and database and notify the client when their shop is ready.

The back end uses PHP and interacts with Kubernetes through its REST API. I also added a recurring billing process and automated jobs to suspend and renew any subscription.

Career Academy

A job board for companies to post job openings and potential candidates to view and apply for open positions.

I built the application from scratch using Symfony with multiple different roles. Companies can register to create relevant job openings and manage applications for each position. Candidates can view, search, and apply for open positions.


An open-source billing and invoicing application. I created the project from scratch, working through many iterations and upgrades. I built the UI, back end as well as API. I'm overseeing and reviewing contributions from the community, giving feedback and assisting in any open issues, and working on ensuring the application is user-friendly and easy to set up.

My Little Garden

A mobile app that lets users track the growth and progress of seeds planted in their garden.

I built this as a weekend project for my kids when they were busy planting seeds. I then published the app to the mobile app stores and got overwhelmingly positive feedback. The app was the number one trending app in its category a week after its release.


An open-source PHP library for managing and integrating payment gateways into any project.

I was recently appointed as the new maintainer of the project after many contributions and am currently in the process of evolving the library to modern standards.
