Senior Software Engineer

Confidential has initiated a strategic program named Experimental Learning to improve its Analytic Testing capability in order to better leverage its insight on customer behavior. A primary objective is to speed up product business decisions based on analytic data in order to improve the eBay user experience. There are various efforts today within eBay that have adopted an analytic testing approach for all business decisions but these have developed as separate efforts instead of under standardized processes and systems. The issue is that eBay now has various experimentation processes and systems with either limited or no integration with each other that results in a collision of experiments as they are executed simultaneously on the eBay site. There is also no single view or dashboard of all experiments currently running on the site which hinders the ability to manually coordinate the experiments across the different groups. The Experimentation Platform will enable eBay to test different versions of a feature in production, with real eBay users, to determine which version yields the best ROI. This analysis will enable the business to pick the winning version of a new feature that will maximize revenue for eBay.

MyEbay: My eBay is a project under the selling domain. This feature helps the user to keep track of all the activities performed. It provides list of all the items sold and bought. The user is also able to view all the activities pending from his side in the form of reminders.

Responsibilities:

• Analyze and understand the requirements.
• Prepared detailed class diagrams, Activity diagram, Sequence Diagram.
• Develop and implement complete end-to-end functional requirements
• Document the entire program developed.
