Freelancer profile translated to English.
Back to original languageAbout Yannis
Welcome to my profile.
Full-time freelancer since 2018, I specialize in creating mobile applications.
I started developing my first iOS applications in 2009, then quickly took charge of the solo development of all native iOS applications for ARTE and many other references on the AppStore.
Since 2016, I have also specialized in NodeJS (TypeScript) with a Firestore + CloudFunctions stack (via Firebase/GCP) to serve mobile content in a scalable and secure manner.
My great autonomy and rich experience have often led me to play a Tech Lead / CTO role. I take great pleasure in understanding market issues, making relevant technological choices, recruiting a team, and then guiding that team to deliver great applications.
I have had the opportunity to address numerous issues related to: mobile content distribution (APIs, WebSockets), media storage and consumption (photos, video, live), secure and biometric authentication, creation of modules / SDKs, subscription systems, and payments.
I would be delighted to discuss your needs and see how we could collaborate.
Looking forward to discussing your project,
