Portfolio - What I've worked on

Now

I am becoming a web3 developer and diving into everything which interests me. It's pretty neat having the knowledge of being a fullstack dev and expanding this with concepts like having blockchain backend, a oracle hybrid dapp or a decentralized data storage like ipfs.

Some examples - click on the image to get to the deployed apps:

Supply-Blockchain

This repository containts an Ethereum DApp that demonstrates a Supply Chain flow between a Seller and Buyer. The user story is similar to any commonly used supply chain process. A Seller can add items to the inventory system stored in the blockchain. A Buyer can purchase such items from the inventory system. Additionally a Seller can mark an item as Shipped, and similarly a Buyer can mark an item as Received.
