Hi, I’m Holger Sielaff, a Freiburg-based software developer with more than two decades of professional experience. I freelance for clients worldwide, focusing on backend architectures, PHP, Python, and cloud-ready solutions. Over the years I’ve led development teams, managed IT operations, and built secure, scalable systems for sectors like healthcare, logistics, and education.
I enjoy turning complex requirements into robust software, partnering with customers to deliver value, and maintaining an agile mindset. When I’m not coding, I manage projects and help teams improve processes, while keeping a hands-on technical edge in PHP, Django, Phalcon, WordPress, Odoo, and related technologies.
