Personal projects and SaaS products I've built.
A free, privacy-first suite of Dutch financial calculators in one place: net salary, maximum mortgage, allowances, savings, and box 3. Every calculation runs client-side, with privacy-friendly analytics that only shows statistics and never your inputs, built on a single source of truth for fiscal figures that is verified each year against official sources.
A SaaS platform that turns any HTML form into a reliable submission pipeline, with 10+ spam checks, complete action logging, failure alerts, and a flat monthly fee that never charges per submission. Built originally to stop rebuilding the same form backend for every client project; now used by developers and agencies managing forms across multiple sites.
A simple quiz application built with Java Spring Boot, fetching trivia questions from an external API and securely processing answers without using a database.
A project for a client who wanted to share sensitive information
Automated solution for managing my Linux configuration with Ansible, allowing quick setup and easy restoration of my ideal environment across machines.
