I started studying computer science at 13, and that early curiosity has stayed with me ever since. What kept me in it wasn't the code itself. It was the moment a hard technical problem turned into something people actually relied on.

Early on, I moved into blockchain, back when most engineers treated it as theory. I wanted to build the real thing, so I went after production work. I delivered an enterprise solution for maritime logistics and a central bank digital currency system for the Philippines, both live systems where accuracy had to hold up from day one.

At Vechain, the scope of what I owned changed. I moved past pure engineering into owning products end to end. I became one of the main contributors to vechain sdk js, used by 90,000 plus developers every week, and I led Greencart.vet from the ground up to over a million monthly active users. I wasn't just writing the code anymore. I was deciding what to build and how.

That's still how I work today. I designed an AI tool that turns electrical panel photos into CAD drawings at MGAR Energy, and I built a renewable energy tokenization platform processing over 150 transactions a second at Digital Energy. Now at DXC Technologies, I drive the architecture behind a geospatial monitoring system for Italy's Ministry of Environment. Whatever the project, I take something complex, figure out what actually matters, and build it so it holds up. That is the approach I bring to every system I touch, turning complicated ideas into software that holds up under real use.

I'm looking for my next chapter as a Tech Lead or Lead Software Engineer with backend engineering and blockchain depth ready whenever the problem calls for it.
