The architect: M. De Castro, Manila

Nearly 20 years in tech. Zero tech-bro energy.

I started as a software developer in 2007, straight out of a CS degree from De La Salle Lipa. Eleven years of enterprise systems taught me how software breaks, and how to build it so it doesn't.

Then I went freelance: chatbots, ads, and since 2022 GoHighLevel. Today I'm the engineer agencies call when their workflows, custom code and integrations need to hold up. I work from Manila with clients in Australia, New Zealand and the US.
