Summary
👤
Senior🎓
Top SchoolAdam Czepil is a Senior Software Engineer based in Sydney with 10 years of experience building high-throughput, cloud-native Java and Kotlin systems across companies like Atlassian and Google. He combines strong mathematical and algorithmic foundations with a pragmatic focus on non-functional requirements—availability, performance, and observability—often owning some of the highest-throughput services in his orgs. Adam has led small teams to deliver developer-facing tooling (CLIs, PaaS UX) and redesigned data layers using patterns like AWS Single Table Design and CQRS. He is a quick learner and process improver who moves initiatives from 20% side projects onto team roadmaps, improving testability and reliability along the way. Comfortable across the stack, he’s hands-on with GraalVM native images, DynamoDB Global Tables, Kubernetes, streaming systems and performance engineering. Less obvious: his career shows a pattern of turning ad-hoc duties into repeatable platforms that save teams time and reduce operational risk.
