Senior🎓
Top SchoolEmmanouil Gkatziouras is a seasoned software engineer with a decade of experience building resilient, data-driven backends and cloud-native platforms from London. He has led platform and cloud initiatives—introducing Terraform, private Kubernetes clusters, multi-cloud strategies and event-stream replication—while architecting performant ETL and streaming pipelines with Flink, DataFlow, Pub/Sub and Kinesis. Comfortable shipping both infrastructure and application code, he pairs Spring Boot and Java microservices expertise with hands-on work on databases (Postgres, InfluxDB, DynamoDB) and IaC for AWS and GCP. An active open-source contributor, he has improved the InfluxDB Java client and added an Alpakka connector for InfluxDB, reflecting a practical focus on observability and streaming integrations. Colleagues know him for balancing roadmap-level cloud architecture and on-the-ground engineering—often surfacing reliability and cost-optimization wins that aren’t obvious from feature metrics alone. He also writes technical content for developer communities, translating complex systems into clear, reusable patterns.
