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.
