What I'm looking for

My career path is toward becoming a Principal Developer. I love working on big systems with huge traffic and dealing with difficulties.

At Custodiem by Bitflyer, I maintain and support legacy systems and develop the crypto webhook and crypto event processor services.

At Liquid by Quoine, I focused on backend work rebuilding the Liquid Platform from Ruby to Python Django and migrating users and asset balances. At Myria, I worked on an NFT marketplace and an L2 core platform on StarkWare, including transaction processing for NFT activity.
