Collaborate with cross-functional teams to drive the seamless integration of APIs and solutions into the gateway and broader ecosystem.

Provide relevant knowledge transfer to new team members and assist in guiding Junior developers in their day-to-day tasks.

Apply critical thinking and problem-solving to challenges, proactively seeking guidance from senior developers or leadership to develop constructive solutions.
