Top SchoolSebastian Wagner is a Principal Engineer and solutions architect with 13 years of professional experience, currently shaping architecture and delivery at Xero from Christchurch, New Zealand.

Comfortable across Java, web front-ends, and distributed systems, he is known for translating complex requirements into pragmatic, testable solutions and for sustaining community-driven projects at production scale.
