Behind the Code

I am a creator at heart and an engineer by trade. My passion lies in constructing digital ecosystems that are robust, scalable, and user-centric. Specializing in Node.js, Java, and Google Cloud, I focus on delivering high-quality solutions for web and mobile.

My journey began at Going2 Tech, where I evolved from a developer to a technical leader. I've had the privilege of architecting solutions for diverse sectors, from sports social networks like Footbao to lifestyle apps like Greeko, always focusing on delivering tangible value through code.

When I'm not coding, I'm immersing myself in virtual reality, strumming my guitar, or exploring the latest in tech. I believe that a well-rounded life fuels creative problem-solving.
