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 web developer and technical partner who continues to build side-projects. I also explore emerging tech, especially around AI and automation.

(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.
