Full Stack Engineer

01. About

I'm a results-driven technical leader with 4+ years architecting secure, scalable solutions for financial services, on top of 7+ years in full-stack engineering. I've partnered directly with the CTO and Managing Director to align technical roadmaps with business goals.

My focus is payment processing, open banking, and PCI-DSS compliant systems — built primarily with PHP (Laravel & Drupal) on AWS infrastructure. I balance architectural oversight with hands-on delivery, and I care a lot about code quality, mentorship, and predictable, on-time shipping.

Currently based in the Netherlands and open to new opportunities.
