Design systems that degrade gracefully without impacting the user experience
Work with product, security, infrastructure, and SRE teams to deliver accurate balances, holdings, and transactions to clients
Our technologies:
Node.js and MongoDB services for scraping and acquisition

Strong experience using AI tools for software development, learning, and sharing ideas
Clear communication with a broad range of cross-functional partners
