Hello, I’m Dariusz and welcome to my personal website!
I’m a Staff Engineer with over 10 years of experience building and scaling fintech systems. I’ve worked across the full stack—from architecting backend services to developing modern frontend applications—delivering solutions that serve hundreds of thousands of users and handle billions in assets.
My experience spans system architecture, technical leadership, and hands-on development in highly regulated environments. I’ve led initiatives including platform migrations, OAuth2 authentication systems, RESTful APIs, and employer portals. I’m skilled at both building greenfield projects and modernizing legacy systems, having driven major upgrades across PHP versions, containerization, and database platforms.
I work primarily with PHP, JavaScript/TypeScript, React, and AWS infrastructure, with growing experience in Go. Beyond coding, I mentor engineers, establish technical standards, and collaborate with cross-functional teams to translate business requirements into scalable technical solutions.
I hold a bachelor’s degree in Computing & IT and Business from The Open University and stay current through continuous learning. When I’m not coding, you’ll find me playing guitar, on the tennis or basketball court, or spending time with my family.
I’m interested in opportunities that value practical solutions, technical excellence, and continuous innovation.
