Solid software for complex domains.
I design, build and modernise backend systems for companies where software simply has to keep working. Most of my work is in fintech, terminal logistics and legal tech. The more complex the system, the better.

WHAT I DO
Backend first, pragmatic across the stack
Legacy migration & modernisation
Moving ageing applications to modern .NET step by step, while the business keeps running and no knowledge gets lost along the way.
.NET Framework → .NET · Delphi/WinForms · EF CoreCloud & DevOps
Azure infrastructure and DevOps pipelines that make releasing boring. Everything automated and tested, so a bad release is easy to roll back.

Systems I’ve built and kept running
Share registration platformFintech · Equiniti2024 – now
Backend development for share registration software, where every number has to be right and every change has to be traceable. I also run the Azure DevOps pipelines and play a key role in the migration to modern .NET.
Terminal management systemTank storage & logistics · DWG2022 – 2024, two engagements
A central control application for liquid bulk terminals. I translated business requirements into technical designs, built the guidance that steers vehicles across the terminal and took the system to production, including the Azure DevOps pipelines behind it.
Legal & fintech projectsLegal tech · Epona2018 – 2022
Document management and integrations for law firms and financial clients. Part of it was new features, part of it keeping mature codebases healthy.
HOW I WORK
Understand, build solid, ship boring
01
Understand the domain
Before I write any code I want to understand how your business actually works, whether that’s a tank terminal, a share register or a legal workflow.
02
Build it solid
Sensible architecture and tested code that your own team can take over, with no clever tricks that only I understand.
03
Ship it boring
Automated pipelines, reversible releases, migrations without downtime. The best deployment is one nobody notices.
