Alex Viscreanu is a Senior Software Engineer with 11 years of experience building cloud-native backends and developer-facing tooling, currently based in Brno and working at Spacelift. He has deep Go expertise demonstrated by designing declarative cluster resize APIs and optimizing Scylla Cloud’s autoscaling and bootstrap workflows, and has repeatedly driven migrations from Python to Go to improve performance and maintainability. Alex blends systems-level thinking with developer experience improvements—leading platform initiatives at Kiwi.com, consolidating tooling and CI/CD, and contributing UX-focused front-end changes in open-source projects like the high-profile Zed editor. He’s comfortable across the stack, from implementing editor workspace features and Git-status UI tweaks to architecting streamed search pipelines and shadow-traffic validation tooling. Pragmatic and measurement-driven, he leans on observability to uncover non-obvious bottlenecks and has a track record of unifying duplicate flows into single, well-tested implementations.
