Summary
👤
Senior🎓
Top SchoolElias Karakoulakis is an Observability Lead and R&D Electrical & Computer Engineer with 14 years of hands-on experience designing resilient cloud-native platforms, site reliability improvements, and smart-building IoT systems. He blends deep observability and Kubernetes expertise—from refactoring Prometheus and FluentD pipelines to driving service-mesh and ArgoCD improvements—with a long-running passion for home automation and embedded integrations (KNX, OpenZWave, Elixir-based controllers). Comfortable switching between C++, Elixir, JavaScript and infra-as-code, Elias pairs pragmatic SRE practices with a business-aware approach honed by a decade managing construction and smart-building projects. An active open-source maintainer (knx.js, openzwave-shared, Drizzle) who also authored cross-language daemons and protocol clients, he brings rare cross-domain fluency from on-prem bare-metal clusters to cloud-managed Kubernetes. Based in Athens, he’s as likely to apply kubectl to a cluster as he is to troubleshoot a KNX installation in the field.
