Senior Software Engineer (Infrastructure)Google Nov 2018 - Jul 2020Mountain View, Ca, UsI work on Scaffolding, an internal framework that simplifies C++ RPC server development at Google. Our largest clients are YouTube, Assistant, and Search, and we have thousands of users across the company. Our clients have strict performance requirements, so all of our features must take performance into account.Some highlights from this project: * Added a dependency injection framework, which increases developers' velocity and simplifies their code. * Added support for gRPC-backed Scaffolding servers for both sync and async threading models. * Guided users how to use our framework and build robust Google servers -
Senior Software Engineer (Ads)Google May 2017 - Nov 2018Mountain View, Ca, UsI worked on Google Ad Manager's real-time bidding (RTB) C++ server, which retrieves third-party bids for millions of programmatic ad auctions per second. Specifically, for a particular ad auction, the server must find all interested parties, send them each a HTTP request, receive bid responses, filter invalid bids, and return the rest to the auction within hundreds of milliseconds.Highlights of this project: * Built a system to deliver auction win notifications to third parties in real time. The system ensures 99.9% of notifications are successfully delivered and uses queuing and retrying when appropriate. * Redesigned our pipeline to ingest new ads for malware detection in real time instead of in batch processing. * Managed engineering work for critical features (e.g. compliance with the EU's GDPR laws) across five different teams * Led several projects to improve C++ code health

Senior Software Engineer (Infrastructure)Google Jan 2016 - Jun 2017Mountain View, Ca, UsCoroner is a 20% project that ingests, analyses, and presents data from C++, Java, and Go server crashes across Google's stack. On Coroner, I built a centralized analysis service that runs custom functions in real time on each ingested coredump (C++/Go) and heapdump (Java). Google server owners write these functions and submit them to the centralized service.An example of such a function is a "heapdump reporter", which provides aggregate statistics about the Java heap at the time of GC thrashing or OOM. The service had to pay special attention to load balancing and scalability. For example, the heapdump reporter function needs to load a multi-gigabyte file into RAM every time a Java server at Google OOMs. (I also spent time optimizing this function itself, which must efficiently aggregate across millions of nodes in the server's live object graph).

Senior Site Reliability Engineer (Docs)Google Oct 2016 - May 2017Mountain View, Ca, UsEnsured the scalability, reliability and availability of the Google Docs suite (Docs, Sheets, Slides, Drawings and supporting infrastructure), which are all written in Java.* I implemented automated capacity tooling for our services. The tools took into account future demand, redundancy, and the geographic locations of our users and backends, acquired capacity, and updated our production footprints.* For our batch pipelines, I created reliability guidelines and standards and helped debug scalability issues. In particular, I created a minified database dump that downstream pipelines used to save terabytes of wasted I/O every day.* I implemented a fault injection service for Java servers at Google, which allows service owners to simulate added latency and high error rates when conducting disaster recovery tests.* I specialized in issues related to Java GC thrashing. I tuned the GC settings and improved Java code to avoid using excessive memory.* I served on the SRE on call rotation and debugged critical issues in real time.
