About Guillaume

Having been immersed in the world of applications since the first iPad, I passionately design and develop native iOS applications since 2010.

MY SPECIALTY

iOS Expert, Technical Leader, Product Manager and Entrepreneur, I have been able to experience different roles during my career and my specialty is to support startups in Lean Startup: I propose to create a usable prototype with your customers in 15 days/3 weeks so that you can iterate very quickly to design the most relevant product possible.
I can also help you recruit a team and possibly train new recruits in compliance with good practices: Continuous Deployment, Agility, Unit Tests, ...

YOUR APPLICATION

The golden age of applications is certainly behind us, so designing an application is above all making the right choices:
- Should we implement notifications or rather improve Onboarding?
- How do we increase the acquisition rate?
- And the retention rate?
In addition, an application must remain very simple and it has very little time to convince its new customers: 80% of downloaded apps are uninstalled after the first use.
I put my experience on the subject at your service and your success is really important to me.

NEED EXPERTISE?

Your application is already launched and has created a buzz, but you have performance, reliability and/or your development costs are exploding?
Congratulations on your success already! And good news: I can certainly help you, do not hesitate to contact me!

TO SUM UP

In software development since 2004, I master all aspects of the development of a mobile application: from the creation of a server in the Cloud to its deployment on users' devices.

Freelance and Entrepreneur since the end of 2013, I share my experience with the teams in which I work.
