You are familiar with cloud technologies, particularly AWS, and have experience with containerization tools like Docker. Your database skills are solid, especially with PostgreSQL, and you understand how to optimize queries and manage data effectively. You thrive in collaborative environments and enjoy working with cross-functional teams to turn innovative ideas into real products. You are motivated by the mission of building a global payments platform and are eager to tackle complex challenges.
