gm gm, I'm Justin (Sardius on twitter and Farcaster) and I currently run a web3 dev/consulting business helping my clients build, launch and improve onchain products. I've been building dApps since 2021, and have a background in data analytics since 2015. I have been active in crypto since 2014, ran a mining business (BTC, ETH, LTC, Dash) from 2017 to 2018, and ran operations for ImpactDAOMedia in 2022, helping launch a decentralized book. I'm passionate about regen causes, and was originally inspired to get into crypto way back in the day after reading the slatestarcodex on slaying moloch. I'm currently building on Base, focusing on building novel onchain solutions, and focused on exploring the potentials of miniapps for my users and clients
