ExperienceProduction engineering for AI & data systems

Feb 2026 - Present Bellevue, WA Full-time

Software Engineer / Databricks

  • Built an MCP integration that lets AI agents perform CRUD operations on attribute-based access-control (ABAC) policies in Unity Catalog.
  • Designed a system to purge orphaned access-control classifications, improving policy-evaluation performance.
  • Created LLM-as-judge benchmarks to objectively measure agentic capability, sharpening prompt engineering and agent-harness evaluation.
May - Aug 2024 Bellevue, WA Internship

SDE Intern / Amazon Web Services

  • Increased RDS Data API throughput by up to 16× for read-heavy workloads, in Java on AWS infrastructure.
  • Designed and tested load-balancing heuristics and low-latency query-distribution strategies.
  • Weighed design trade-offs for complex API interactions and shipped the full implementation in Java.
