• Support the firm’s strategic decision to move to Agile methodology by participating in the Agile Transformation Team and restructuring the engineering functions into SCRUM teams. Our vertical was the first to migrate over completely to Agile in all of Technology Org.• Brought in a senior leader to build a Big Data team, stand up 2 large Hadoop clusters and collaborated with Risk and Marketing data scientist to develop fraud and demand-gen models, generating a 3x ROI annually for the depreciated life of the investment.• Partnered closely with Informatica to build an enterprise-wide data integration platform that unified data acquisition & routing, some ETL, metadata capture, and data profiling. Did several POCs on their Ultra Messaging Queue system to attempt near real-time data acquisition.• Developed a 3-year platform architecture that balanced investments in Teradata, Hadoop and Informatica to handle structured/unstructured data processing and analytics, migrating ELT to ETLT to achieve higher compute cycles efficiency, support next-generation modeling & graph processing, while reducing the overall compute and storage cost.

• Took the offer by CTO to join the Data Management group to bring an engineering perspective and experience to the organization.• Centralized all aspects of data engineering (i.e. dev, qa, infrastructure, ops) under one team to achieve better delivery through synergies from closer relationships between the functions, better frequent communications and unified strategy. This empowered the global teams in San Jose, Austin, and India to operate at a higher level via bonding as a team with a management structure that could make decisions faster.• Negotiated contracts ranging from $5M to $25M with vendors while adhering to the capex and depreciation budgets on a quarterly basis.• Negotiated vendor partnerships to do joint-development of new industry leading capabilities: Teradata performance analysis tools and Informatica ETL-Hadoop integration.

• Asked by the VP of Merchant Services engineering to take over the team when it came under him as the firm began to focus in that area.• Launched Peer-2-Peer (P2P) payments and Student Accounts enabling distinctly consumer activities to acquire users and increase stickiness.• Enhanced and fixed Transaction History and Payment details as it was a major issue based on consumer’s feedback that they couldn’t easily grasp their balance status.• Improved the password recovery process flow which accounted for 5.5% of consumer contacts globally, the 4th biggest reason.

• Led the engineering team responsible for supporting merchants off-eBay as PP began to expand its presence throughout e-commerce.• Launched Website Payment Pro composing of a) Direct Payment allowing merchants to process credits directly via an API, b) Virtual Terminal for merchants taking payment over the phone, c) Auth-Capture providing industry standard splitting between the authorization of funds and the capture of funds, d) next-generation Express Checkout with new merchant websites integration via APIs to leverage Auth-Capture.• Kicked off the first mobile payment products at PP. In the spirit of minimal viable product, released features using SMS and IVR with basic functionality that required a handful of resources in an abbreviated development cycle. Reducing time-to-market allowed quick customer feedback to shape the product’s evolution and PP’s Executive’s decision on strategically investing in this area.

• Asked by the VP of Engineering & Architecture to take over the project to scale the core Oracle DB to keep up with the tremendous transaction growth.• Rallied the team by listening to their concerns and ideas of how to solve the problem using DB sharding & 2-phase commit.• Recovered the schedule and delivered the biggest architectural change at that time on schedule for the holiday season.

• Led the engineering team responsible for integrating PP with eBay after the acquisition. Help team overcome challenges operating in a startup mode to adapt to a larger process intensive environment.• Improved Checkout flows via switching from screen scraping to using eBay’s internal APIs. This encouraged sellers to accept PP to raised coverage of listings from low-50% to mid-70%. This improved the overall paying experience and increased buying velocity on eBay.• Built the Shipping product in a 3-way integration with eBay and USPS/UPS. Allowed sellers to print legal USPS/UPS shipping labels and pay with PP becoming the fastest growing product for several years. Solved a major pain point for the sellers, bringing convenience and productivity to their business operations.• Built the first PP Incentive Engine, handling the tracking and redemption of eBay Gift Certificates, Coupons and Points.

• Rewrote the middle-tier servers processing Credit and Debit card transactions being called from the live website in C++.• Reengineered the original code, documented the business processes, and architected new servers using Design Patterns.• New architecture allowed the business to easily switch between credit & debit card processors as the need arose.

• Developed tools for the Domestic Equities market making desk.• Building a modern 3-tier client/server platform to replace the mainframe system used for trade execution.• Deploy newer technologies that could provide a GUI interactions, scale cheaply, quickly adapt to new requirements and be supported from large skillset pool.

• Developed tools and automation for the Domestic Equities programmatic trading desk.• Helped improved the trading platform’s ability to execute and settle trades daily while reducing the need for headcount growth.
