Back to original languageAbout Yohann
Hello,
I have been supporting French and foreign companies in their Mobile development strategies on iOS and Android for 16 years.
This amounts to over 200 native mobile applications developed for, among others: TF1, France Televisions, SNCF, Citroen, Total, Veolia, Pepsi, General Electric, as well as startups.
In parallel, I publish SYMBYOZ, a SAAS back-office solution optimized for managing all types of data. In short, a tool that will save you between 2 and 4 months of development from the launch of your project.
Since 2022, I have also been involved in the Cardano blockchain, for which I created "Mantium Wallet", a native mobile wallet for iPhone that supports features absent in other wallets, such as minting NFTs directly from an iPhone.
My strengths:
-----------------
+ I can code any type of native mobile application on iOS and Android.
+ If innovative solutions need to be imagined, that's for me.
+ Ergonomics and design.
+ IT security and cryptography, a major future challenge, following the release of AI like ChatGPT which facilitates the work of hackers.
+ I know how to adapt perfectly to each industry: understanding the needs and challenges of my clients, as well as the expectations of their clients/users.
+ Perfectly bilingual French / English
My areas of expertise:
--------------------------------
+ Mobile apps: Objective-C, Swift, SwiftUI, Java
+ Databases: MYSQL, MongoDB, Firebase, Parse-server
+ Web: Php, Javascript, HTML, CSS, REST, XML, JSON, Symphony, Sonata, Doctrine
+ Protocols: Https, Websockets, Streaming, Bluetooth, RFID, Wifi Direct
+ Third-party services: Git, AWS, Stripe, Parse, Firebase, MailGun, Twillio, Maps, OpenIA,...
+ Security: SSL, OAuthV2, Cryptography, Biometrics

It was a pleasure to work with Yohann. He has very strong technical skills and helped a lot not only to realize the project but also to rethink it in a much more efficient way. He is very very proactive when it comes to developing and that is exactly what I was looking for.
I will continue to work with him in the future and I highly recommend him.
