My main area of expertise as a full-stack developer involves creating interactive, immersive websites, focusing on metaverses and 3D animations. My interest in web3 has been a significant part of my 10-year career in the blockchain industry. My primary tech stack includes Three.js, TypeScript, Next.js, React, and Supabase , but I am flexible and excited to learn other technologies. In 2023, I served as the lead Three.js developer at Montra, a web-based video editing startup. Between 2020 and 2023, I was the lead developer at XELEVEN, a metaverse development studio, where we undertook projects for notable clients like NIKE. Our metaverse, Spirit Realm, was featured at NFT NYC, Times Square NYC, and Red-Eye metaverse magazine. In 2022, I contributed to RaveSpace's launch of the Musee Dezentral project, a museum dedicated to NFTs. Throughout my career, I have been part of several prominent blockchain companies, including Coinsquare, Canada's largest cryptocurrency exchange, and IOST in Asia. I have given talks and shared my insights on blockchain technology at venues like Chainlink HQ in Berlin and the Google Campus in Warsaw.
