Anthony STEPHAN GUILLOTEAU. Android enthusiast since the very first version. This operating system has created a brand new open world to passionate tech monkeys like me. The development of mobile applications is now one of my biggest passion: I love making the final users happy by meeting their individual needs, with a pleasant and luxury experience on their phones.

Today I’m a Freelance developer (located in Paris region 🇫🇷). This status allows me to meet a lot of people and work in different teams. This makes me grow quickly and allows me to discover new technologies and work methodologies. In parallel I design, develop, publish and sell my own applications on Google Play.

I’m a great traveler. I love losing myself in countries far away from my home, getting out of my comfort zone, meeting amazing people… My favorite trips: 🇨🇺 🇵🇪 🇮🇨

I’m a watch enthusiast and passionate about the fine Horology. I’m watchmaker by training. I also do 3D printing at home, for the last 8 years.

As a freelance developer…


As an Android developer, as a Technical leader, or as a Product Manager, I can step in your projects from scratch or on existing applications.

I’ve already accompanied the creation of B2B and B2C applications, but also SDKs and low-level apps. I’m used to practicing Agile methods as the organization of my work.

I really enjoy the innovative things: if I have a real fit with your product and your spirit, I will invest myself a lot to empower your services and your applications!

When I work on an application or a complete solution, I really need to have a clear product vision before starting the development.

It is mandatory to me to have the ability to interact with the PM, PO, QA, the designers, the other developers, etc. in order to provide a quality application inserted into a product vision, in accordance with the need and the existing.

I’m developing apps with Koltin (and Java), the Android Jetpack components, Firebase, Retrofit, OkHttp, Dagger, Compose, etc. as well for smartphones, tablets, smartwatches, and also for Android Automotive OS.
