Hi! my name is

Freelance Backend and Infrastructure Consultant

About me

I Craft Web Applications with you

With over 20 years of programming experience and an academic background in mathematics and computer science, I bring a level of stability in codebases and certainty and comfort in teams. Using a growth mindset I can help craft reliable systems, upgrade legacy projects, and automate the boring stuff one step at a time. And let’s use A.I. wisely so we have great control and not end up with slop. 

I’ve led teams, shipped large-scale backend systems, modernized outdated stacks, and built tooling to help developers move faster and safer. I care deeply about maintainable code, pragmatic solutions, and happy engineering teams.

In this day and age I’ve been of course also utilizing A.I. tools to speed up deliveries and bring a level of team-comfort and security to the software I deliver.

I’m currently available for part-time freelance projects and technical consulting.

What I like to do

Modernizing Legacy Systems

Still running on PHP 5 or Symfony 2? I help companies bring old codebases into the present—with safe, testable upgrades and containerized deployments.

DevOps & CI/CD Pipelines

Whether you're on AWS, GCP, or just curious about Docker, I can help set up tailored CI/CD pipelines that match your workflow and remove manual bottlenecks.

Backend Architecture & Development

From real-time APIs to messaging systems and internal platforms, I design and build solid backends that scale and evolve with your business.
