FlexyPay App - Ultra Dynamic and Diverse Payments
Because of the powerful identification features of FlexyPay, the store owners can feel confident in the visitors behaving as they should.
FlexyKey - Future of IoT
http://flexaccess.se/flexykey/Combining these concepts with modern smartphone apps, directly available in everyone’s pocket, allows for highly efficient and convenient services.
I have, together with FlexAccess, developed a technology called FlexyKey, where efficient micro-hardware is combined with smart technology through a mobile app service.
The FlexyKey hardware allows web- or GSM-based controlling of up to 64 different electronic devices in a single unit. It’s a generic, flexible unit that supports a wide range of devices, such as vending machines, doors, gates, car washes, and golf carts, to name a few.
With simple adjustments, it can be adapted to almost any kind of system.
Assistans För Dig
Livetree - Social Streaming Platform
The app is inspired by Netflix but contains almost exclusively indie content.
I implemented HLS technology for high-quality streaming over HTTPS, combined with Fairplay technology for secure media content delivery.
The client is based in the UK but the team was fully remote and distributed all across Europe.
