Seppe Brosens

Hey, I'm Seppe β€” a second-year Cloud & Cybersecurity student at Thomas More Geel. I'm fascinated by the way digital systems can be broken and, more importantly, how to defend them.

I chose this field because security and hacking genuinely excite me. Understanding how attacks work, finding vulnerabilities, and building resilient systems β€” that's where I want to make my mark.

Why Cloud & Cybersecurity?

From an early age I was curious about how technology works beneath the surface. That curiosity grew into a real interest in cybersecurity β€” how systems can be exploited, and how to stop it. When I found Applied Computer Science with a specialisation in Cloud & Cybersecurity at Thomas More Geel, it felt like the perfect fit. It combines hands-on technical training with the security focus I was looking for.

Future ambitions

After graduating, I want to build a career in cybersecurity β€” ideally in a role like penetration tester, security analyst, or SOC engineer. I want to work at the front line of digital defence, helping organisations understand and close their vulnerabilities before attackers can exploit them.

built.

Semester 2 — SKIL2 Group project · 6 members In progress

ArcJet

Shared Web Hosting Platform

A managed shared hosting platform purpose-built for PHP (Laravel) and Java applications, hosted on a physical server in the Thomas More datacenter. The goal is to let developers deploy and manage applications without touching infrastructure β€” while enforcing strong security standards out of the box.

ArcJet runs on a Proxmox hypervisor with a Kubernetes cluster (1 master + 3 worker nodes). Users authenticate via a web interface, pass through two firewall layers, and are routed to either a client or admin dashboard based on their role. Clients get a dashboard with a file browser, database management UI, DNS settings, backup tools, and a log viewer. File uploads trigger an automated pipeline: the API detects the runtime, selects a Dockerfile template, builds the image via Docker, pushes it to the registry, and Kubernetes spins up an isolated pod per client namespace.

πŸ“ Translating requirements into architecture decisions and writing a formal concept & analysis report
Semester 1 — SKIL2 Group project

OptiLoad

Freight Sharing Service for Companies

A logistics platform designed to help companies reduce the number of trucks on the road. When two companies each have a truck that isn't fully loaded, OptiLoad matches them so they can combine their freight into a single trip β€” cutting emissions, reducing traffic, and lowering costs for both parties.

A service that allows companies to register freight loads, find compatible matches based on route and capacity, and coordinate combined shipments through a shared platform. The focus was on the matching logic, user flows, and making the collaboration between companies as seamless as possible.

πŸ’‘ Designing a service around a real-world problem with tangible environmental impact
🀝 Collaborating in a team from concept through delivery, including stakeholder alignment
πŸ“‹ Requirements analysis, planning, and structured project documentation
Personal project

The Thonkpad

Self-hosted Home Server

A repurposed ThinkPad laptop running Ubuntu Server as a personal home lab. I turned it into a fully self-hosted mini server running several Docker containers, giving me complete control over my own services β€” no subscriptions, no third parties.

πŸ”’ Self-hosting and securing services: reverse proxies, firewall rules, and access control
Personal project Secondary education

Youth Movement Website

Website for my jeugdbeweging

Built a website from scratch for my local youth movement (jeugdbeweging). It was my first real web project β€” no templates, no builders, just writing it myself. The site is no longer under my control, but the foundation I built is still being used today. Hosted via GitHub Pages.
