My name is David and I have been laser focused on React Native development for the past 8 years, which has enabled me to become one of the top 20 contributors on Stackoverflow. I hired Matthys to be my right-hand and help me to scale our services.

We are based in France, speak english for all our communications and use qwerty keyboards. It’s for us right now, book a call to see if we can help you.

Unlike lengthy contracts that bind you for months and require a six-step paperwork process, our service is available whenever you need it. You have the freedom to pause or cancel at any time and can restart whenever it suits you.

We can partner with you and your team on a rolling basis, or we can enhance your team’s skills with a one-off workshop. We are flexible to suit your needs.

We are going to present the details of our partnership below. However, if you’re interested in workshops, you can directly jump to workshops.

How does it work?

Step 1

You have React Native features or fixes that need to be done.

Whether it's big features, small fixes, or relase workflows, no matter the complexity, we've got your back. We will provide you with a custom backlog tailored to your needs.

You can add any tasks requiring our attention to this backlog. There are no limits or constraints.

Step 2

We will design and develop until its release.

We'll tackle your custom backlog one task at a time.

You have the freedom to reshuffle, invert, add, or remove any tasks that have not yet started. You set the order, and we'll proceed accordingly.

Step 3

Satisfaction guaranteed.

"Using your app should spark joy."

We've always wanted to say that, and we've always believed in it too.

We offer unlimited revisions, comments, and critiques on any task. No matter how high you set the bar, we aim to meet and exceed it. Our goal is to help you build not just good, but memorable products.
