It started with games. As a kid I hosted my own Minecraft servers: plugins, port forwarding and the occasional crash at the worst possible moment. That's why I picked IT in high school, and I never looked back.

At university college, team projects like [Rydes](/en/projects/rydes) and [HelloMeal](/en/projects/hellomeal) taught me the code is rarely the hard part. Since then I've built the mobile and web side of a contact centre platform at [Ideal Systems](https://www.ideal-systems.com) and client products at [Codifly](https://codifly.be). From 19 October I'm a software engineer at [Warren](https://warren.eu).

I like small teams, strict types and owning a feature from first sketch to production. Got something in mind? [Let's chat](/en/contact).

## Experience

### Software Engineer · Warren

Oct 2026 → Present · Ghent, Belgium

Building the tools that make money make sense. At Warren I work on pensions, investing and the data behind them, so every employee sees their numbers clearly and makes smarter choices with them. Financially fearless, one chart at a time.

Stack: TypeScript, React, Expo, NestJS, GraphQL, Drizzle ORM, AWS, SST, Pulumi, Docker, Bun, pnpm

### Web & Mobile Developer · Codifly

Oct 2025 → Oct 2026 · Affligem, Belgium

Shipped client products on web and mobile in a small product team, from the very first Figma frame all the way to the app store.

- Shipped features end-to-end across Expo apps and web dashboards, on a typed tRPC + Prisma stack that caught my mistakes before users did
- Worked directly with designers and clients, turning feedback into small, frequent releases instead of one big scary one
- Raised the quality bar with end-to-end tests in Playwright and infrastructure as code in Terraform. Fewer surprises, fewer late nights

Stack: TypeScript, React, Expo, tRPC, Prisma, Tailwind CSS, AWS, Terraform, Playwright, Docker, Figma

### JavaScript Developer · Ideal Systems

Sept 2023 → Oct 2025 · Vilvoorde, Belgium

Built the mobile and web side of a contact-centre (CCaaS) platform for telecom customers. Yes, the people who answer when you call.

- Built React Native apps that let contact-centre agents handle calls and customers on the go, desk optional
- Designed Node.js + DynamoDB services with Zod-validated contracts shared between client and server, so both sides finally agreed on what the data looks like
- Rebuilt web interfaces on React, Vite, Tailwind and shadcn/ui, side by side with design
- Owned customer-reported issues from triage to fix, playing translator between support and engineering

Stack: TypeScript, React, Expo, Node.js, Express, AWS, TanStack Query, React Router, Zod, Tailwind CSS, shadcn/ui, Oxlint, Docker
