I'm a creative front-end developer focused on optimizing user experience. Design driven by data, interfaces with pleasing aesthetics, and clean maintainable code are my main principles.

I make sure the Exivity API is running smoothly.

Working on developing software for people or companies in Finance, HR and IT in the last 10 years, I am an professional Backend Developer with some mixed feelings about Frontend. But I learnt to never say never.

Coming from academia (neuroscience) and arts (contemporary dance) I've circled my way to software five years ago where I get to combine both intellect and creativity.

There's a good chance that you'll find me in the garden, growing some veg and fruit following permaculture principles. But you might also catch me building wooden furniture or fermenting some of the fruit and veg 🍾.
