Hi, my name is
Hey there. I am a Computer Science student based in Rotterdam, last year at Hogeschool Rotterdam. I grew up online. The internet raised me, and I have been building back ever since.
I put feeling into web development. Software is just code until somebody cares about it, and the moment a user feels that care, the work earns trust. My ambition is small and stubborn: build things that give people goosebumps, the good kind.
I think in futures and in layers. Defence in depth is a mindset before it is a checklist: secure defaults, least privilege, every input treated as adversarial, every dependency held at arm's length. I try to ship things that age well, that break loudly when they break, and that keep their promises when nobody is watching.
Tools I reach for, and theory I keep close:
Python, C#, JavaScript, TypeScript, MySQL, HTML, CSS, PHP
Docker, Git, GitHub, VSCode, Figma, Vercel, Bitbucket, Jira, Trello, Slack
ASP.NET, ReactJS, NextJS, Jest, Pytest, Laravel
Operating System, Concurrency, Data Structures and Algorithms, Advanced OS, Databases, OODP
Migrated a legacy PHP codebase to a modern Next.js plus Payload stack and shipped it solo. Owned the design, the build, the deploy, and the keep-it-alive.
Next.js 16 · Payload CMS · Self hosted · CSP · Rate limiting
End to end work for a Rotterdam workshop. Self hosted Payload so the client owns their data, not a SaaS. HTTPS, secure headers, image optimisation, structured data.
Next.js · Payload CMS · Self hosted · DevOps
Quiet typography, tuned motion, premium feel without sacrificing performance. EN and NL bilingual content modelled cleanly with Payload localisation.
Next.js · Payload CMS · EN / NL · Lighthouse tuned
Replaced a leaky pile of hardcoded SharePoint links with a hardened, role aware content hub. Provider agnostic file access, server side filtering, AES-256-CBC plus HMAC-SHA256 (encrypt then MAC, PBKDF2-SHA256 at 100k iterations, machine bound, constant time verified).
ASP.NET · C# · Microsoft Graph · OAuth 2.0 · AES-256 · RBAC · Audit logged
Casual group project. React Native + Expo prototype walking users step by step through applying for financial arrangements. Lived in a test environment, never shipped publicly.
A mobile application for onboarding new employees at Antes GGZ.
A console application for managing a restaurant.
Final year Computer Science student, actively looking for full stack developer and engineering roles. If you have an opening or just want to say hi, my inbox is open.
