Joshua Walters Email & Phone Number

Cupertino, California, Us

Built microservices to automate Kubernetes cluster provisioning across multiple providers (AWS, GCP, etc), and analytics deployments (Spark, Trino, etc) for large scale use. Built back-end REST services (Golang), UI (Bulma), and E2E CICD deployment pipelines. This reduced time from cluster request to job execution from two weeks to one hour.Built a RAG LLM pipeline and API for processing and querying information about analytics systems and their underlying Kubernetes compute resources. Used vLLM, Milvus, and Golang.

San Francisco, California, Us

Built a process mining application (using AWS S3, EC2, DynamoDB, Docker, Kubernetes, Terraform, Jenkins), which automatically correlates uncorrelated data sets. Built Real User Monitoring (RUM) backend (Kafka, Druid, Helm, Trino, AWS), a low latency analytics reporting system.

Sunnyvale, Ca, Us

Built multiple data pipelines (using Hive, Pig, Oozie, Hadoop), and analytics reporting systems (using Druid, sketching algorithms, Hadoop). Published multiple patents, papers, and presented work at conferences (Hadoop Summit, XLDB, IEEE) on the topics of big data processing and analytics.
