Frameworks Data Group - Schemas

• Improved HubSpot's object/property schema service (millions of daily requests) by adding validation and caching ensuring correctness and low latency. Added two new operators for calculated properties and auditing for property changes using kafka.

• Improved object type management services and databases, improved hollow-based caching and reduced client startup time from 5s to under 2s thereby improving request serving speed and added REST endpoints to support new workflows.

• Managed the full lifecycle of serving object/property definitions using Memcache, Hollow, and MySQL and reduced improved query performance by 30% by making effective use of indexes and distributing load by using pagination and batched queries.

Performance Engineering Optimization

• Built tools/libraries to measure performance for various modules running on the vehicle to keep track of metrics like CPU util, gpu latency etc. Focused on AB Comparison of two vehicle log runs and providing stats like avg, total, percentile comparison of different scopes running on the system across different modules.

• Built Airflow pipeline to precompute data for visualizations using protobufs and flatbuffers and display them in a UI built using IMGui framework.
