• Designed and obtained product alignment on the multiple permission resolution algorithm for Dynamic Data Masking, providing customers a highly configurable method of controlling access to column data

• Owned the query-time masking expression authorization procedure that involved performant service calls between the BigQuery SQL parser (Dremel), authorization service, and an internal Data Policy Service API in C++ and Java, enabling the launch of Dynamic Data Masking to thousands of BigQuery customers

• Delivered the design and C++ implementation of the DATE_YEAR_MASK predefined masking expression in Dremel in under 3 weeks as a post-launch fast-follow in order to meet growing customer requests for more masking types

• Implemented the Google Cloud Platform virtual private cloud security horizontal for the Data Policy Service and automated its validation

• Developed the Python end-to-end test setup and dozens of tests for BigQuery Dynamic Data Masking

• Wrote the Spanner database interface library and RPC handlers in C++ from scratch for the Analytics Hub Service control plane API, allowing customers to symlink and share datasets with each other and enabling a fast launch to feature preview for over 50 major cloud customers

• Integrated Analytics Hub's split permission model into the legacy BigQuery permission check architecture

• Led one other engineer on the development of a garbage collection pipeline and internal API in C++ and Java using Spanner database indexes and queues for on-demand removal of references to deleted Policy Tags from every BigQuery table schema

• Built Java Flume pipelines to remove deprecated Policy Tag references from more than 7 million BigQuery tables, defining and documenting the process, for the first time, that the rest of the engineering team used for 2 years afterward

• On-boarded a team of 12 engineers for hand-off of the Policy Tag Manager service to the new Data Catalog team in Warsaw, Poland

• Co-designed and implemented the indexing and hierarchical search expansion of BigQuery tables by column Policy Tag in C++

• Developed a flexible and reliable device imaging framework in Objective-C for use as a standalone framework and incorporation into a larger quality assurance (QA) framework

• Maintained, added features to, and documented the architecture and use of a QA suite for indefinite, device-driven stress tests used by over 10 product areas and 30 QA engineers around the world

• Responsible for automating the weekly week-long stress testing of the HomeKit API
