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.
02System integration
We connect the systems your business already runs on: your accounting software, your CRM, your webshop, your ERP. Anything with an API or a messaging interface can be connected — including systems that take hours or days to answer. Our integrations wait, lose nothing, and pick the work back up.
03Business process automation
We automate the manual work between your systems: the re-typing, the exports, the spreadsheet that travels by email. It keeps running while nobody is watching, and leaves a record of what it did. We build our own workflow platform, Supertaak, on exactly this ground.
04Cloud infrastructure and DevOps
The servers and services your software runs on, set up so a release is routine rather than an event, and so you can see it is healthy without asking anyone. We favour open source, and before adopting anything else we ask how hard it would be to leave later. Migrations, cost reduction and security hardening included.
05AI and LLM integration
We add AI to the software and processes you already have, and we are straight about where it saves real time and where a person still has to sign off. Behind it sits production experience: RAG pipelines, agentic workflows and LLM integrations that run in our own products every day.
06Advice 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.
We do not only build for others. We build and run our own products — TenderScan.nl and Supertaak — software that users lean on every day. That is where our advice comes from.
About us
Software people can depend on.

I'm Patrick Roozeboom, founder of Hexxore and a software and DevOps engineer with twenty years of working experience. The company exists since 2018; the experience started well before that, building and running systems in professional environments where downtime was never acceptable.
We work across the whole stack, because that is the order I learned it in: infrastructure first, then the software on top of it, then the automation that puts it into production. It means one party takes your idea to a system that actually runs, instead of three parties each holding one piece and pointing at the others.
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.
Building and running our own products taught me to think like the business owner who pays the invoice. And our first client from 2018 still runs on our systems — by now, he builds along with us.
