YouTube Voice Search

Improved voice tips (query suggestions) for voice searches on YouTube.

* Migrated voice tips logic to an alternate server. Configured tips generation service to provide tips over RPCs.

* Designed and defined metrics for measuring voice tips click-through rate and their effectiveness.

* Built logging infrastructure for voice tips, and computed the metrics from logs.

* Gradually rolled out changes, ensuring indicators were maintained or improved during the stages of the rollout.

Technologies and skills: C++, Go, design and documentation, experiments, unit testing, e2e testing.

Google Ad Manager Deals Serving Team.

Built a serviceability tool for Programmatic Guaranteed deals in Google Ad Manager:

Developed multiple pipelines that interact with the ad serving stack to test agreements between advertisers and publishers, ensuring they can transact.

* Analyzed and manipulated billions of production logs from multiple sources using a MapReduce framework in C++.

* Implemented monitoring and alerting: quantified relevant metrics, and built a dashboard in Python to expose them.

* Made system maintainable by implementing unit and E2E tests.

* Pipelines run daily in production, allowing early problem detection to save lost revenue and customer relationships.

* System is fully integrated with Google’s production tools and test infrastructure.

Search Ads Quality Engineering Productivity team.

Created a system to reduce log data collection time by 80%, replacing the need to write SQL queries:

* Processed unorganized log data via MapReduce in C++ into SSTables sorted by relevant parameters.

* Stored SSTable output in a C++ backend lookup service, enabling data retrieval through RPCs.

* Developed a frontend system using HTML, CSS, Javascript, and JSLayout that takes user specifications and then queries the backend for results.

Enabled gathering input and loading proto-buffs from recordIO files from an alternate source: a virtual storage system.

Utilized internal Infrastore API to generate list of all available service backends and display on frontend in an intuitive manner.
