Cyrus David Pastelero

Software Engineer • building things that matter

I turn late nights and rabbit holes into products people actually use. Currently obsessed with AI, scalable systems, and making complex things feel simple. Based in Cebu, Philippines.

Fun fact: I grew up playing Minecraft, which taught me that even the most complex structures start with a single block.

About

I'm a software engineer who believes the best code is the code you don't have to write. My philosophy: "What I cannot build, I do not understand."

When I'm not shipping features at 2am, you'll find me chasing a new hobby — currently hiking, previously Muay Thai, cycling, and running. I'm the type who dives deep into something, then moves on to the next obsession. Still think Minecraft is one of the best games ever made.
