Summary
🤩
Rockstar🎓
Top SchoolJustas Černiauskas is a software engineer with a decade of experience building and maintaining distributed systems, with deep domain expertise in observability—metrics, logs, and traces—and a focus on improving on-call workflows. He spent several years at Uber working on internal tooling that helps engineers debug faster and get more value from telemetry while on-call, and has strong backend experience including rewriting Node.js services to Go for performance gains. His background spans system architecture and SharePoint-era enterprise development through to high-scale infrastructure, giving him a pragmatic appreciation for both legacy constraints and cloud-native practices. Based in Vilnius, he combines hands-on implementation with a preference for developer ergonomics, often designing tooling that surfaces actionable insights rather than raw data. An under-the-radar strength is his track record of translating observability signals into operational improvements that measurably reduce incident time-to-resolution.
