Hey, I'm Sebastian. I build things because I enjoy it, these days with AI as a serious tool in the workflow rather than a gimmick — this is just my little corner of the internet to show a few projects and write down what's on my mind.
From tiny automations to full-blown apps — I lean on AI tooling as a standing part of the process, not a crutch, and mess around with all of this simply because it's fun, not because I have to.
C#/.NET WPF kiosk app built to run entire multi-day events unattended — direct DNP/Canon SDK calls for driver-level printer control, a live camera feed pipeline, and a custom template renderer. One codebase powers several white-labeled booth products and holds uptime for days without a restart or a memory leak.
Browser-based drag-and-drop template editor for the photobooth stack — live canvas preview backed by a shared clipart/template library in PHP + MariaDB. Exports straight into the exact binary layout format the booths read on-site, so editor output and runtime format never drift apart.
C# filesystem watchdog that trails WinBooth, catches finished event photos the moment they land, and pushes them out via FTP in real time. Shipped as its own standalone licensed product with an independent update channel and activation system — field-tested under real event load, not a lab demo.
Multi-tenant SaaS for beauty studios — Node/Express + MariaDB running booking calendar, customer records, inventory, and invoicing in one stack. Tenant isolation, licensing, and role-based permissions all run on shared infrastructure, no per-customer deploys.
Turns event photos into live cartoon portraits drawn by a robotic arm in real time — full pipeline from photo capture through stylization to SVG-to-G-code conversion to pen-plotter strokes. Sold as an event-tech product with its own subscription model and multi-tenant backend.
The AI photo kiosk that feeds Cartoonbot: guests get transformed into a stylized cartoon portrait, then queued straight into the robotic arm draw queue. Per-event licensing, live credit metering, and automatic refunds baked in when a generation fails.
A single-player Pong rebuilt from scratch — except the court is a full 360° circle and you are defending the entire perimeter, not one paddle on one side. Flask/Python backend with MariaDB-driven content, real-time paddle physics and collision detection running on plain HTML5 Canvas — no engine, no WebGL, just requestAnimationFrame and trigonometry.
