The corporate database is the centralized repository for Google’s IT / Operations data. Currently, it stores information about user accounts, groups, and infrastructure.— Track the corporate database library usage on the client side.While backend logs can report the time taken to process each backend request, they do not include network latency to the end user; also, a single command invocation may require multiple backend requests to finish. The goal of this project is to implement a server that receives metrics (as proto-buffers) and makes them available to query and analyze. The server is written using Go, the client written using Python, collect and send the metrics with no added latency to the user.— Provide SRE support for the corporate database. As an SRE my responsibilities were:1. Address all of the bugs opened against the database.2. Turn up a new cell in Europe.— Work on the code, fix bugs and improve performance.

- Coordinate bi-weekly releases.We have 11 applications in the Wildfire suite. The release was on a bi-weekly schedule, and each team is responsible for releasing their product.As a Release Manager, my role is to supervise the release and coordinate cross-team and cross-product dependencies.— Improving Wildfire release process.This project is all about designing the tools and process to release our ruby-on-rails based applications to production while taking advantage of Google internal tools.— Cross-applications updates.As a release manager, my responsibilities include cross-applications updates. Here are a few examples:1. Feature gating release.Our engineering team in London implemented "feature gating" functionality, which allows us to switch on/off features instantly via a web interface. Enabling this feature required coordination between our teams to perform several applications and infrastructure updates over a two months period. My role was to track, supervise and provide support for our engineering team.2. UI-Toolkit coordinated release.Our applications use a standard UI library, called UI-Toolkit. A recent release included a security issue; my role was to coordinate an ASAP release of all of our top applications and provide support wherever it was needed.

Wildfire Pages is the most used application of the Wildfire suite. It allows customers to create pages on their Facebook brand page with social authentication without any Web Developing knowledge by simply using pre-made templates (or ordering a custom template). The page’s content can be Gallery with votes, sweepstakes, signup forms, and many other possibilities. I was a part of the team working solely on Pages and the libraries/small applications that it was using. We worked on designing, implementing, testing, supporting and releasing the applications.

Senior Software Engineer

Wildﬁre Bspoke is a pluggable application into Wildﬁre Pages. It is designed to transmit the data submitted by the end user to the signup form to our customers’ proprietary CRM. I single handedly designed the application from the ground up with HMAC-secured connection between Pages and Bspoke (for fraud prevention). It has built-in support for multiple CRM platforms : Salesforce, MailChimp, CheetahMail, ExactTarget and basically any CRM accepting FORM POST, JSON or SOAP encapsulated data. The data is sent to the CRM in a background job decoupled fromthe initial HTTP request. The project was later on-boarded along with me to the Pages team, who are currently maintaining the project.

Wildﬁre Account Management is the administration panel of Wildﬁre. It allows companies to create accounts for their employees, create teams, deﬁne permissions and link or conﬁgure their attached Facebook accounts. I was a part of the team working solely on Account Management alongside the client library "Accounts Client", which is used by all the other applications to make speciﬁc accounts or permission queries to Account Management. We worked on designing, implementing, testing, supporting and releasing the application.
