I'm a software engineer with 8+ years of experience. For the last 7 I've built payments, invoicing and fraud-prevention systems for Lookiero & Outfittery, a subscription fashion company that operates across Europe.
I'm backend-focused (Java, Spring Boot, event-driven microservices) and comfortable on the frontend with React and React Native. Before that, I programmed a PlayStation 4 game.
What I've been working on
- Integrating payment providers: Stripe, Klarna, iDeal and PayPal, on web, iOS and Android
- Multi-currency payments and invoicing for launches in new markets
- Moving a legacy Vert.x/Groovy monolith to event-driven microservices step by step
- Fraud prevention, automatic invoicing and data pipelines into Databricks
- AI-assisted development with Claude Code and coding agents
Tech I use
Side quests
- android-package-uninstaller: Python tool that removes Android packages over ADB
- PythonAI: computer-vision experiments with OpenCV
- advent-code-2020: Advent of Code 2020 solutions in Python
Off the keyboard: video games, Android tinkering, and science-fiction books.
