Postmates is disrupting local commerce by providing a marketplace where consumers can purchase goods from any local restaurant or store, and local couriers deliver the goods to their home in minutes. Postmates has unlocked on-demand local shopping — providing consumers the convenience of super fast delivery for the largest selection of goods (anything in the whole city!); the benefit and scale of e-commerce for local merchants; and more flexible work for couriers. From the love shown by millions of customers in 300 US cities; to the hundreds of millions of dollars that our investors have trusted us with; to 2M+ orders (and growing) that we deliver every month -- Postmates' success story is one that I am proud to be part of.I lead the worldwide engineering team, having tripled it in last year to ~120 engineers now, developing all technology for Postmates. This includes mobile and web applications for our buyers, sellers and couriers, backend services to power these applications, data science and machine learning systems (e.g. for predicting fraudulent transactions), algorithms to optimally match buyer demand to fulfillment supply, and engineering infrastructure like logging and monitoring services and build systems. From July 2016 to March 2018 (1 year 9 months) San Francisco Bay AreaDirector of Software Development @ eBay I led the team building "Services Development Infrastructure" for eBay Marketplaces Services. This is a real-time monitoring, anomaly-detection, and auto-recovery system. The system automatically collects a large amount of data (~1GB/s) from various eBay services, aggregates it and slices it in millions of time series, does automatic anomaly detection on the data, raises alerts, and attempts to do auto-recovery for certain class of issues. The system works in real-time – and uses highly efficient algorithms for processing & storing the large stream of data. The backend system is built using Java, using Cassandra for storage. The front-end includes web-UI, and the iOS/Android mobile apps.In addition, I led the team building the Shopping Cart & Checkout services for eBay.com, and delivered >$250M of revenue (GMB) growth from shopping-cart innovations. Technologically, in one line, we built a front-end UI using the latest browser based technologies powered by a distributed java-services based highly-scalable backend.Key highlights of my tenure in eBay include:- Led hiring efforts for eBay Seattle in 2013, and built a brand new team of ~20 developers & managers in ~7 months.

From September 1999 to September 2012 (13 years 1 month) Greater Seattle AreaSoftware Developer @ Qualcomm Worked as a member of the software development team of the CDMA based cellular Base Station Transceiver Subsystem (BTS). 1) Designed and implemented Developer Diagnostic Monitor (DDM), a multithreaded run-time software debugging tool to diagnose and monitor the execution progress and the state of an embedded software application. The tool, designed using the object oriented paradigm, uses an embedded server to communicate with its Java based client. My role was to design the tool and write the embedded server. The coding was done in C++, using Tornado and Visual C++ as development environments. 2) Worked on the low level design of 'CDMA channel management', an internal network management module of Halibut BTS software. The module was responsible for managing (fault handling / allocating / deallocating) all the CDMA channels available in the subsystem. The design was an object oriented one, with a proposed implementation in C++.3) Worked on integration of the Tetra BTS software with the Base Station Controller(BSC), Base Station Manager (BSM) and other components of the system.
