Custom software, automation and infrastructure
Custom software built to survive production.
We build custom software, connect the systems a business already runs on, and automate the processes in between. Then we stay to keep it all running.

What we do.
We take on custom software development, systems integration, infrastructure work and consultancy. Architecture, security, straight advice, and the operational discipline that keeps software running once real people depend on it.
Custom software development
We turn a rough idea into software people can actually use: web applications, APIs and internal tools built around how your business really works. We'd rather ship the smallest version that is solid and grow it than deliver something broad that cannot hold weight.
Cloud infrastructure and DevOps
Linux, containers and infrastructure as code, plus the deployment pipelines, monitoring and backups around them. We favour open source, and before adopting anything else we ask how hard it would be to leave later. Migrations, cost reduction and hardening included.
Systems integration and automation
We connect systems that were never designed for each other, then automate the manual work between them. APIs, webhooks, message queues and long-running jobs that keep a business moving while nobody is watching, built so you can always see what they did.
AI agents and automation
We build with AI coding agents daily and make tooling for doing it properly. Expect straight answers about where agents genuinely help, where a human checkpoint is non-negotiable, and what an audit trail must capture before you can trust the output.
Technical consultancy
Sometimes the useful thing is an engineer in the room rather than a delivery. We join your team for a while to work through an architecture, plan a migration, or get a stalled project moving again. Expect us to say what we actually think, including when the answer is to build less than you asked for.
Advice and second opinions
A review of what you already have: the platform, the code, the security posture, the hosting bill, or a supplier proposal you want checked before signing. You get a written verdict with the reasoning, ordered by what to fix first. No obligation to have us do the work.
About us
Software people can depend on.
I'm Patrick Roozeboom, founder of Hexxore and a software and DevOps engineer. I started the company in 2018.
We work across the whole stack, because that is the order I learned it in: four years of Linux servers, firewalls and telephony first, then four more building backends, APIs and integrations on top, then the automation that puts it all into production. It means we can take something from an idea to a system that actually runs, without handing it over halfway.
Building systems people depend on teaches you something specific. What breaks is almost never the clever part in the middle. It is the deployment at the wrong moment, the migration nobody rehearsed, the integration that quietly stops working and tells no one.
So the work goes into the parts that don't demo well: automated tests, backups, monitoring, and an audit trail that can answer what happened and when. That is the difference between fixing a problem and guessing at one, and it is what keeps a bad afternoon from becoming a bad week.
