In turn, lead a number of those efforts including: * Helped set the partner integration services direction, including API design of RESTFul interfaces for client access to internal service, individual services using Spring and Mule and deploying an authentication and access control framework using Sonoa ServiceNet along with a custom LDAP schema. * Reworked Search internals to add support for multiple search servers, including Solr, partially in support of internationalization efforts. * Lead evaluation of third party CMS products. * Developed the architecture for integration layers around a new Order Management System. Invite Media, Senior Software Engineer, Feb - Dec 2008 Built a demand-side platform for online advertising, recently acquired by Google. * Participated in the design and implementation of the ad platform using an array of technologies including Java, Python, Hadoop, RabbitMQ, and memcached and deploying to Amazon EC2. * Designed and implemented cluster monitoring and management system, using Zenos. * Built analytics data layer using SQLAlchemy and PostgreSQL. * Performed scale-out testing and optimization of high speed event based data capture subsystem, responsible for capturing ad impressions and tracking pixels. GSI Commerce, Principal Software Engineer and Architect, 2002-2008 Maintained and enhanced e-commerce platform used by a provider of outsourced online stores for major retail firms, such as Toys''R''Us, Radio Shack, and Ralph Lauren. * Responsible for architectural governance, design, and leadership for a wide range of projects with emphasis on those involving the shopping cart, third party integrations, internal inter-system integrations, security, scalability, and internal tools suites. * Provided technical assistance and guidance to the business, including technical direction, project cost estimation, and evaluation of third party technologies. * Worked with launch teams and partners to help define solutions for new partners unique needs, while folding them into a unified underlying platform. * Lead several performance and scaling related projects including distributed caching, memory reduction, and Q4 performance profiling. * Lead, designed, and/or implemented a range of third party payment schemes including Google Checkout, various Gift Cards, ACH, PayPal, Bill Me Later, and other similar systems. * Primary application developer responsible for security, including PCI compliance for a level 1 service provider. This effort included integration with FIPS-140 hardware security devices. * Responsible for evaluating and leading the implementation of new technology initiatives, including new platforms, application servers, and application frameworks. * Responsible for a number of internationalization project from data encoding schemes to selecting European payment providers. Trintech, Senior Software Developer, 2000-2002 Worked on a variety of banking and e-commerce applications, primarily eIssuer, an electronic wallet. * Implemented extensions to eIssuer to support payment via Secure Electronic Transaction (SET), a public key infrastructure (PKI) for credit card transactions. * Application architect and web-tier development lead for the eIssuer product. Researched new features and technologies. Worked closely with Product Marketing and Management in establishing product direction and providing technical expertise. Prototyped enhancements using a range of technologies including Servlets, JSP, EJB, RMI, and XML. * Major areas of responsibility included: portability across a range of J2EE platforms including Tomcat, JRun, WebSphere, Weblogic, and iPlanet, cardholder data security including design and implementation of schemes for encryption of persistent data and key management, and internationalization (I18N) of a product sold in a variety of non-western locales, including CJK support. HealthAxis, Senior Developer, 1999-2000 Extended and enhanced e-commerce site, since sold to Digital Insurance, selling a range of third party insurance products. * Participated in re-architecting the site from a proprietary solution to a web application based on Servlets and JSPs. * Designed and implemented a data driven form processing package used for validating, persisting, and transforming data on on complex forms, such as insurance applications. Platinum Technology (now Computer Associates), Senior Product Developer, 1995-1999 Worked on the Enterprise Performance Management (EPM) product suite, as a member of the kernel team. EPM is a performance monitoring application that gathers data from servers (Unix and NT), networks, applications, and RDBMS engines in order to graph trends, detect anomalies, and perform notifications and corrective actions. Also worked closely with the POEMS project, a systems management framework within which EPM integrated with other Platinum products. * Ported EPM architecture to over two dozen Unix platforms, including SunOS, Solaris, AIX, and HP-UX, as well as Windows NT. * Extended the EPM core architecture, including re-engineering to allow the ad hoc loading of data collection routines, thus providing for easier addition of new monitors better modularity and independent testing of components. * Supported and maintained EPM source base, serving as primary resource for issues involving portability, linking, builds, shared libraries, interprocess communication, networking, and performance tuning. * Built and maintained a reusable library of shared components which originated in EPM and were used by other products as part of the POEMS architecture to provide system independent abstractions of common OS services. * Designed and implemented, in Perl, a distributed auto-build system that built and tested EPM across all supported platforms daily and reported any failures to preserve portability and to support continuous integration among several distributed development teams. Feith Systems and Software, Senior Software Engineer, 1989-1995 Major projects were Feith Document Database (FDD) and Netware for Unix. FDD is a document imaging system build around MS-Windows clients and Unix Servers, using commercial RDBMSs and a locally written Optical Disk Library Manager (EasyJuke). Netware for Unix is a source code product from Novell, which Feith OEMed on the AT&T and NCR platforms. * Trouble shot and tuned for performance the FDD client's SQL interaction with database servers. Supported various RDBMSs including multiple versions of Oracle, Informix, and Sybase, * Wrote a series of test and support utilities for the EasyJuke Server in TCL/TK that used TCL extensions written in C to wrap the EasyJuke client API. * Wrote platform specific code for Netware for Unix and fixed deviations found by a Novell provided series of application, API, and network level certification test suites. * Wrote custom applications as part of systems integration efforts around FDD in C, ESQL/C, Informix-4GL, and Informix-SQL. Step-Saver Data Systems, Support Analyst 1987-1989 Step-Saver provided Office Automation and Billing systems to the Medical and Legal professions.
