Francis Dierick Portrait

Me, Myself & I

I’m a software developer from Belgium. I’ve been building digital products since the dawn of the internet & am fascinated by the power of technology. My current focus is on digital native apps. I am particularly interested in building apps for health & fitness. If you’re interested in working with me, check out my CV


Climbing is really important to me. I have spent most of my life climbing on rock & ice. I took a long hiatus about 5 years ago & it’s one of the things I regret most. I’m back now & enjoying it more than ever. To give back to the sport that gave me so much I am building ClimbChat. I also think modern climbers use way too much chalk. I’m creating a product to help fight chalk over-use at ChalkRebels


You won’t find me on social networks like Facebook, Instagram, LinkedIN et al. I believe the modern ad-supported “social” web has morphed into a user-hostile environment & I have chosen to opt-out. Whenever possible I choose paid over freemium, native over web & decentralized over centralized.


I’m proficient in many tech stacks but currently choose to focus on developing native apps for the Apple ecosystem (Swift/ObjC/Xcode). I like my backend technology stack to be boring & stable. This means I prefer Python over Javascript & Swift over React Native. Yes, I do web development front & back, but I like my sites static, simple & fast. Like this one. Without all the JS nonsense!


After my first startup I wrote a book about entrepreneurship. The content is a bit dated now but I’m still pretty proud of the writing. I’ve since moved on to fiction & ghostwriting. I wrote a couple of short stories & am currently working on two stories: one about the Mystic Lamb & another one about climbing.

Product Philosophy

I strongly believe in minimalism to build the best product. Most digital product developers ask these two questions to guide development:

We’ve seem massive improvements in the average usability of digital products over the last decade or so. Thanks to these two questions.

Yes, we have better products today. But far too often they come with hidden costs. Too often we end up building products that harm users’ privacy & liberty.

To combat this I like to explicitly add a third question during product development:

Somewhere along the way our digital industry has lost sight of the Golden Rule: “Do to others as you would have them do to you.”
