01THE LONGER VERSION

A bit about me

I started coding when I was 14, with a complicated course in C I could not manage at that time. So I moved to Python, and that's how I got into the Informatics Olympiads. By the time I was 17, I was fluent in C, and especially in competitive coding: I've won municipal Olympiads and scored a Mention at the National Olympiad. From there, I went to pursue my passion at university.

Along the way I taught myself the web the practical way: some PHP and freelance WordPress plugins at first, then an extended JavaScript course I paid for with freelance savings. Later I got curious about the world beyond the browser, picking up back-end good practices (Java Spring, Express.js) and even Arduino electronics, one of which ended up in daily use at my mother's workplace.

That passion took me to the University of Maastricht, where I earned my BSc in Computer Science (class of 2026). I got my first taste of production software early, a full-stack internship at Next Generation Sensors in my very first year, building RESTful APIs with Java Spring on PostgreSQL and shipping a responsive Angular.js front end inside a real Agile team.

In January 2025 I founded OrchEcomm, a modular operating system for online stores. It now runs 6 fully working modules with 3 more in beta, connecting 30 e-commerce businesses and 50+ suppliers while orchestrating 3.000+ orders every month. Although I consider education very important, I've decided that for now I want to focus on developing OrchEcomm and gain as much experience from it as I can.

The researcher in me got its outlet in my BSc thesis: Temporal Semantic Proximity Analysis (TSPA), a method for detecting coordinated information operations on social media. It processes up to 500k tweets per campaign through multilingual sentence embeddings and Leiden community detection, surfacing coordinated communities with IO purities of up to 100%, and it taught me that at scale, cosine similarity is a memory problem before it's a math problem.

03HOW I GOT HERE

The short timeline

2026

Graduated: BSc Computer Science

Finished my degree at the University of Maastricht with TSPA, a coordinated-information-operations detector that separates IO communities at purities up to 100% across 14 real campaigns.

2025

Founded OrchEcomm

Went self-employed and built a modular e-commerce operating system: 6 working modules (3 more in beta), 30 businesses and 50+ suppliers connected, 3.000+ orders orchestrated every month.

2023

Moved to Maastricht for CS

Started the Bachelor at the University of Maastricht, and landed a full-stack internship at Next Generation Sensors in my very first semester, because why ease into things.

late 2022

Arduino tracking devices, adopted for real

Completed an Arduino project, a series of tracking devices used at my mother's job to follow her workers' routes, all wired into a dashboard. It started as a funny proof-of-knowledge build and became her workplace's first digitalisation tool, giving real transparency over routes and actions.

2022

Beyond the browser: IOT & back-end

Got interested in IOT and coding for the physical world. Started learning good practices in back-end development (Java Spring, Express.js) and got into electronics and the engineering of physical devices with Arduino.

2021

Fluent in C, deep in competitive coding

By 17 the language that once defeated me became my strongest weapon. Won municipal Informatics Olympiads and scored a Mention at the National Olympiad.

2019

Bought my way deeper into web dev

Saved enough from freelance work to buy an extended JavaScript course and get seriously into web development.

2019

First income: PHP & WordPress

Learned basic PHP and started providing a custom WordPress plugin service on the freelance market, my first real money made from code.

2019

Python & the Informatics Olympiads

Moved to Python, and that's how I got into the Informatics Olympiads, my first taste of algorithms as a sport.

2018

First lines of real code

Started coding at 14 with a complicated C course I could not manage at the time. It didn't stick, but the itch did.
