Software engineer who likes knowing what's under the hood, from BLAS matrix kernels to e-commerce checkout flows.

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.

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.
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.
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.
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.
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.
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.
Bought my way deeper into web dev
Saved enough from freelance work to buy an extended JavaScript course and get seriously into web development.
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.
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.
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.
Currently
OrchEcomm's module ecosystem
Growing the suite past its 6 live modules, with 3 more in full-scale beta.
Azure & AI-agent workflows
Taking cloud past 'basic knowledge', and optimising my productivity by using AI agents smartly.
