Senior Software Engineer

Responsibilities:

• The most complex application developed by the Host Systems group, used throughout the chain for handling large orders for corporate and institutional customers.
• The system manages order creation, pricing, payments, routing orders to various order fulfillment systems, and order tracking. Joined the development team in the intense final months of the project. Worked closely with the lead Business Analyst to help bring the project to completion, allowing me to develop a deep understanding of the system. Recently completed a major enhancement to the order routing software that adds the option to route ship-to-customer orders through the new BN.com fulfillment system.
• Redesigned and extended a critical high-volume web service that provides Confidential & Confidential stores with pricing, availability, and delivery information for millions of inventory items. Provides both REST and SOAP client interfaces, returning data merged from a variety of web services and databases. The new design defines a generic data source interface that runs multiple data sources concurrently using a fork-join pool under the Java Executor service. All data sources implement a standard interface and return the same object type. allowing a straightforward merge phase and easy addition or replacement of data sources.

Consultant

Responsibilities:

• Designed and developed a Flash application to support an experimental psychology research project at Confidential . The software presented users with a series of increasingly difficult jigsaw puzzles. As the user manipulated the puzzle pieces, the system logged detailed statistics of the user's actions. Programmed in ActionScript 3.0 and the ActionScript API, deployed as an Adobe AIR application.
• Developed software to create and manipulate puzzle elements using various 2D and 3D transformations and animations, process mouse events bubbled through the layers of graphics objects, manage two concurrent puzzle instances as the user alternated between them, and collect statistics on timing and user actions.
• Developed a method to increase the accuracy of timing information over that obtained by conventional methods that are subject to variations due to background processes.

Environment: ActionScript 3.0, Adobe AIR.

Selecting an area of text they would like to view video for. The system retrieved the relevant MPEG file from the database, and using time stamp data embedded in the html transcript, extracted a video clip corresponding to the highlighted text in the transcript, and streamed it to the user.
• Solved a persistent error in the software that extracted a video segment from an MPEG file caused by a bug in the way the software calculated which GOP (group of pictures) a timestamp was associated with in the MPEG file, causing the start or end points of the video segment to be a half second too early or late.
• Solved complex timing problems among multiple asynchronous media streams (byte stream from an MPEG encoder, text stream from the speech recognition engine, and SMPTE time code data from the source video in order to embed accurate time code information in generated HTML text transcripts.
