The route so far.

I work across databases, game development and web development, and each discipline sharpens the others. Hardware and electrical engineering are next on my route. I build with curiosity and test with honesty.

Home isn’t one place for me. It’s a blend of cultures and the questions I keep chasing.

A rule I keep“Overthinking is fear pretending to be logic.”

What I work with.

  1. Full-stack foundation

    A working command of the core programming languages, relational databases with SQL, game development in Godot and modern frameworks: enough to build a project from the database all the way to the interface.

  2. Specialising

    Deepening the more specific skills that my possible future roles call for, from systems and firmware security to security engineering, data engineering, MLOps and site reliability engineering (SRE): working closer to the hardware, understanding how systems fit together, and testing, securing and operating software.

  3. Working with AI

    Learning to use AI to my advantage: to research faster, prototype ideas, and review and test my work, while remaining responsible for every line I deliver.

  4. Curious about

    Embedded systems and electronics, where software meets the hardware it runs on, and how machine-learning systems, data platforms and large online services are secured and kept running: MLOps, data engineering, security and SRE.

Off duty.

Outside of code I keep moving. I’m a former powerlifter and table tennis player; today I run, train at the gym and play games to stay fit, focused and balanced.

Current build & roadmap.

The roles in the roadmap are possible destinations for my future career: directions I am interested in and working toward, not fixed plans.

Why these directions?

They share one thread: they are built to last. As connected devices, data and online services keep growing, so does the need for engineers who can secure, automate and keep them running. These roles reward deep, uninterrupted focus on complex technical problems and are engineering-driven rather than client-facing. They also offer strong long-term prospects and a solid foundation for one day building a company of my own.

  1. Student Software Engineer

    MBO 4 · Rotterdam

    Building a broad software foundation: game development in Godot, web development, relational databases and SQL, frameworks such as Laravel, and programming fundamentals across several languages.

  2. Possible future roles6 · Interests, not fixed plans

    • Systems Engineer

      Designing, integrating and maintaining the systems that everything else runs on.

    • Firmware Security Automation Engineer

      Securing the low-level code inside devices, and automating how it is tested and verified.

    • Security Engineer

      Protecting systems and data by finding weaknesses early and building defences into the design.

    • Site Reliability Engineer (SRE)

      Keeping large services fast, stable and available through automation and careful monitoring.

    • Data Engineer

      Building the pipelines and databases that turn raw data into something reliable to work with.

    • MLOps Engineer

      Bringing machine-learning models into production and keeping them reliable, measurable and up to date.

This site is a project too.

Three languages, each doing the job it does best: the same mindset I want to bring to systems and firmware work.

  1. The site

    TypeScript · Astro

    Static, SEO-friendly pages generated by Astro, with every interactive feature written as a TypeScript class, including this board.

  2. The physics

    C · WebAssembly

    The off-duty playground runs on a small physics engine written in C and compiled to WebAssembly.

  3. The deploy guard

    Python

    Before every deploy, a Python auditor checks each page’s titles, descriptions, links and alt text, and stops the release if anything is off.

Final call: say hello.
