As QA Engineer, I tested code for 15 Mattereum Asset Passports and proprietary command-line tools using GitLab CI/CD. I also worked extensively with Git - collaborated with 7 other developers, uploaded code regularly, provided feedback and managed merge conflicts. I used Javascript, node, TypeScript, and XML to create the front-end of website and refactor link-checker tool. I also managed 2 hot & cold crypto wallets using GnosisSafe, ENS, MetaMask and Ledger wallets and minted 15 physical NFTs on the Ethereum and Polygon blockchains. As Project Manager, I utilized Agile Project Management for organizing tech team tasks and projects. I used Wrike very extensively for documenting and updating Checklists that optimized the pipelines and workflows for all of our company's departments - from Legal and Ontology to Sales and of course Tech. I also used Figma to build with our Design and UI/UX team. Show less
