Ad Platform

An advertisement platform to search and add leaflets and promotions on a daily basis and as a dev lead, I had a major impact on the success of that project as I developed all parts of the application, designed the architecture, developed a back-office to manage the data, created a sophisticated SEO concept, and made an API with strict speed requirements. I installed a customized tracking system and built it on top of a billing system, and last but not least, set up everything into a cloud-based environment.

The biggest challenge in this project was the amount of data we had to evaluate every day. Still, we managed it using the right platforms to store the data and use a microservice architecture to scale up or down easily.

Power Plant Platform

A sophisticated system to track the flow between power plants in real time where I was responsible for planning, developing, and maintaining the platform. A very important factor in that project was quality insurance, which I took very seriously. The software has had no major downtimes so far.

Cash Quiz

Cash Quiz is an app where you can win money by answering questions at scheduled times and I was in charge of creating and developing the back-end architecture. We used Node.js in that project—the biggest challenge was to make sure that the users have no possibility to cheat. To that end, we made sure to always have an immutable state.

Financial Trading Platform

A distributed system used to monitor and keep different kinds of financial transactions. These transactions can be spot fx trades, crypto fx trades, future trades, and other smaller trade types. This system is used for larger systems and gives advanced statistics in real-time.
