About me

After 10 years in corporate marketing, I left my 9-to-5 to build a startup in 2021. It didn't scale, but on the journey I enjoyed the intersection of business and technology. Now I work as a freelance fullstack developer. I keep building side-projects and explore emerging tech, especially around AI and agentic solutions.

Professional Services

I'm the fullstack developer you work with when you don't have a dedicated web or product-engineering team. I take things from early concept through build, launch, and iteration, including websites and web tools, automations and integrations, plus tracking and measurement so you can see what matters. One person end to end.

(Personal) Development

After hours, I am pursuing a Master's in Media Informatics, a program tailored towards working professionals that allows me to study in addition to my work. This deepens my understanding of the differenty layers of technology.

When I'm not on my laptop you can find me practising yoga, lifting weights at the gym, or doing indoor bouldering.
