Jan 2024 - PresentStaff Software Engineer
Query Platform Leadership: Lead Query Planning and Connectors work serving hundreds of millions of queries daily across observability use cases, spanning parsers, cost-based optimization, distributed execution engines, and connector reliability.
Federated Data Access: Designed and shipped a production connector platform that reduced engine coupling, expanded from 5 to 15 connectors and 5 to 38 catalog instances, and helped deliver 20+ new data sources in one quarter.
Open Query Systems: Became a Substrait committer (Cross-Language Serialization for Relational Algebra) and contributed across DataFusion, Trino, Iceberg, and Calcite to make plans and data access portable across engines.
Performance Engineering: Delivered 50x production query speedups, 14x large-timeframe query speedups, parser p95 latency reduction from roughly 3.2 ms to 720 us, and roughly 40x lower parser memory.
Production Reliability: Serve as Core Incident Commander for severe incidents; commanded 15+ incidents, responded to 120+ incidents in the last year, and coordinated follow-ups across monitoring, deployment gates, SLOs, and regression suites.
AI Data Infrastructure: Partnered with Applied AI researchers and scientists on service-investigation data paths, retrieval agents, simulation/evaluation environments, and root cause analysis quality loops.
Stack: Go, Java, Python, SQL, Trino, DataFusion, Apache Calcite, Kubernetes, LLMs, RL
Software Engineer, Tech Lead
Data Platform Leadership: Led Dataflow Platform team of 5 engineers responsible for 200+ production pipelines processing petabytes of data daily across Google Cloud.
Platform Transformation: Moved the team from bespoke customer pipeline delivery toward reusable infrastructure for teams and partners; reduced new pipeline development time by 60% and enabled 3x more use cases with the same team capacity.
Operational Reliability: Participated in 24/7 on-call handling P0/P1 incidents, customer escalations, and turnarounds while improving tests, probers, rollouts, support automation, and release safety.
Security & Delivery Hygiene: Led migration to minimal Distroless container images, eliminating over 80% of CVE surface area, and drove multi-quarter migrations and partner launches across data platform teams.
Execution & Influence: Recognized by peers for customer focus, incident support, cross-team technical help, and ability to turn ambiguous platform work into shipped infrastructure.
Stack: Java, Python, C++, Apache Beam, Kafka, Docker, Google Cloud Dataflow, GCP
