🤩
RockstarDaniel Augusto is a Principal Software Engineer with 11 years of experience building data-intensive, distributed systems and streaming platforms, currently leading backend efforts at Comet in Bristol. He has designed and operated real-time pipelines and analytics at scale using Kafka, ksqlDB, Druid, Spark, Iceberg and Kubernetes, driving cost and performance optimisations across multiple organisations. Daniel combines deep data-engineering instincts with hands-on systems work—implementing OpenTelemetry ingestion and trace mapping for production LLM observability and using Redis for efficient trace lookups. He has a strong academic foundation in mathematics and computer science (Master’s, PhD studies) and a history of squeezing orders-of-magnitude improvements from search and storage systems. Colleagues rely on him for technical leadership, mentoring, and pragmatic architecture decisions that align product and engineering goals.

Contributions summary:Daniel's contributions center around developing and integrating OpenTelemetry traces within the Opik backend. They implemented a new endpoint for ingesting OpenTelemetry traces in both protobuf and JSON formats. Key changes involve mapping OpenTelemetry payloads to the appropriate Opik fields and improving trace ID mapping using Redis for efficient lookups. Their work also includes adding support for JSON-based ingestion of traces, enhancing the flexibility of the system.
