Software engineer · Rotterdam
Software engineer behind Vargar and creator of pgkiln, an open-source app builder for PostgreSQL. I take projects from the first requirement to a running product — websites, applications, integrations and the servers under them.
Selected work
Company · Hosting, web & apps
My web and systems practice for Dutch businesses: WordPress websites, business applications, managed hosting and Google services, run as one connected system with one point of contact.
Open source · Apache-2.0
Build database apps on PostgreSQL. In SQL. A low-code app builder modelled on Oracle APEX: reports, forms, dashboards and maps generated from your tables, business rules in PL/pgSQL, apps stored as data you can version in git.
About
I started in e-commerce development, moved through integration work and database-heavy systems, and now run my own practice. That mix means I can talk to a business owner about what they need and then build, host and maintain it myself.
I like quality code, standard platforms and nothing you’ll be locked into later. I enjoy picking up new languages and frameworks when a project calls for them — and I’ll tell you honestly when something isn’t the right fit.
What I do
Understanding what you need, designing the blueprint and delivering the final product — and everything in between.
WordPress and custom-built sites that are fast, accessible and easy for you to edit.
Internal tools and customer-facing apps shaped around how your business works, not a generic template.
Connecting systems — ERP, helpdesk, accounting, fleet — so data flows without copy-paste.
Configuring, securing and maintaining Linux servers so your software stays fast and available.
Domain names, DNS and email set up correctly, secured and documented.
Tracking you can trust and campaigns that get read, measured and adjusted.
