Creation of a contract to receive user payments (payment of $1 in the chain's currency) Development of a Soulbound contract (non-transferable NFT) representing the user's on-chain identity. The soulbound has additional functionalities compared to the standard defined on the different chains. Integration of a Go Backend to verify user payments on the payment contract and mint a Soulbound on the second contract.

Atlas.ki -> Collection of KPIs from the DEX on Pools, Swaps... TFP (Tokenized Financial Products) -> Automation of underlying asset purchases. Use of other technologies such as Ether.js for interactions with the Ethereum blockchain.

Second year of ISIMA internship. I developed from scratch a virtual reality application with the University College Dublin virtual reality lab. This application gives the possibility to perform a therapy session with an Oculus Quest, a virtual reality headset. It was carried on with Unity and C#. The network was set with the Photon Engine for Unity, and virtual reality with the Unity XR Toolkit and Oculus SDK.
