Summary
👤
Senior🎓
Top SchoolSergio Ceballos is a Ruby Framework Architect based in Munich with 13 years of experience building and operating high-performance web and embedded testing systems. He combines deep Ruby/Rails expertise with hands-on DevOps skills—designing CI/CD, managing Linux production environments, and automating infrastructure on AWS. At ESR Labs he built an RSpec-based framework and tooling to test embedded software on target hardware, integrating CAN/LIN/serial protocols and hardware debuggers. Previously he led API and ETL work in microservice ecosystems, pairing TDD/BDD practices with Spark/Scala pipelines for analytics. Comfortable across the stack, he ships reliable production systems and also crafts reporting and aggregation tools using Elasticsearch and Redshift. A pragmatic engineer who moves between low-level system integration and high-level architecture, he quietly bridges testing, deployment, and data workflows.
