Summary
Harry Day is a Senior API Developer with 12 years of experience designing and delivering cloud-native backend systems across Google Cloud and AWS. He has led backend architecture and teams at startups (Buy Somewhere) and feature-led a long-running microservice decomposition for Jira Cloud at Atlassian, pairing hands-on C++, Python, C# and Java implementation with technical design and mentorship. At PwC’s Innovation team he architected GCP microservices and data ingestion pipelines, and more recently he’s driving API work at NurtureCloud. His background in competitive robotics (BLUEsat UNSW) and student leadership—where he grew a software team and built ROS/C++ systems for a Mars rover—gives him uncommon systems-design and embedded-systems empathy for cloud platforms. He’s known as a subject-matter expert in authentication and permissions for complex monolith-to-microservice transitions, and routinely coordinates cross-geo teams to deliver at scale.
