(He/him) | Apps with a dollop of sweetness

Hi there!

I’ve been a software engineering consultant for 10+ years. I’ve been directly involved with small businesses and startups getting their apps off the ground or back in shape!

My main motivation is community. I’ve actively worked with children, refugees as well as software builders both new and experienced.

I dedicate a significant amount of my time to organising conferences, workshops and other events aimed at helping empower folks in their tech journey.

A healthy community is critical to our success. Let me help you reach that AHA! moment.
