Open Liberty Space Sentry Challenge is an interactive Internet of things (IoT) game designed to showcase microservices with modern Java technologies in a fun way. The player can take control of a spaceship made of Lego and 3D printed model using a PlayStation 4 controller and shoot lasers. The goal is to shoot down as many random popup targets as possible within a minute. Since the game's debut, it has become an instant attraction at various developer conferences and local developer meetups. People loved the game's mechanics as it's easy to pick up but also challenging to master.

Moreover, the idea behind the game is to have different technologies working together with the addition of Legos that helped to reach out to audiences and developers of diverse technical backgrounds. We decided to open-source the entire project starting this year, so it can reach out to more people who want to learn Java and microservices using a different approach. We'll document every bit required to run the project, including Lego assembly instructions, Arduino codes, and, most importantly, Java microservices code.

The internal risk assessment portal used by Facebook's Privacy, HR, Global Security, and a dozen other internal teams to manage controls and risks using supported frameworks like NIST, GDPR, ISO 27001, etc. The tool is developed using the same tech stack as the Facebook website and is part of the Facebook Enterprise suite.

I designed and developed the Prometheus endpoint for WebSphere® Application Server runtimes to display PMI metrics in Prometheus format.

The feature performs two operations:
Retrieves the WebSphere PMI data objects by using the JMX Perf MBean.
Renders the data from the PMI data objects into Prometheus format output.
