Summary
🤩
Rockstar🎓
Top SchoolAgo Allikmaa is a software engineer with 12 years of experience specializing in low-level instrumentation, JVM internals, and performance/memory optimization. At Plumbr he builds and tests JVM and language-agnostic agents, designs multidimensional acceptance test matrices, and engineers backend pipelines for high-volume monitoring data while participating in SRE work. He contributes to the widely used OpenTelemetry Java auto-instrumentation, improving agent integration, servlet API support, and concurrency testing. Comfortable reading assembly and bytecode as much as source, he pairs deep systems knowledge with practical automation skills—examples include an automated crawler for real-world browser testing and a Java audio streaming library born from his hobby projects. Based in Estonia, he blends forensic debugging of third-party software with production-hardened delivery of observability tooling.
