Global Growth Hacker, Trustpilot

Download Resume

I love discovering products, brainstorming and taking a product from idea to implementation.

I am (really) passionate about what I do, and thus I don't consider work a seperate part of my life that I just go and do 8 hours each day to earn a living. I use most evenings to better myself, experimenting with the latest stuff and pushing the borders of what I thought possible.

I live for those "EUREKA" moments.

I'm easy to talk to, and I love talking to users, programmers and clients. My perspective is that everyone hoards brilliant gems of knowledge that they're more than willing to share with you, if you just take the time to listen and let them express their own passion to you.

I am an expert in the LAMP stack, but I enjoy getting my hands dirty with new technology. Currently I am in love with Node.js and React.
