Software Developer in Cebu City, Central Visayas, Philippines

An advertisement platform to search and add leaflets and promotions on a daily basis. As a dev lead, I had a major impact on the success of that project. 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.

Cash Quiz is an app where you can win money by answering questions at scheduled times. 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.
