Sean Manalili

Principal Developer & Solutions Architect

I architect cloud systems that carry real production load.

And I still write the code that runs on them. Twenty years across travel, insurance, banking and HR tech — taking a business problem nobody has fully specified, proving the risky part with a POC, then building it with the team rather than handing down a diagram.

Right now I lead a cross-shore team of engineers split between the Philippines and Australia, working on AI in hiring.
