Applications Architect/Technical Lead

• Designed and implemented GM's next generation Confidential software from the ground up. Challenged with extremely unrealistically aggressive timelines, worked with an understaffed team and faced many road-blocks that required parallel workarounds and resolutions to keep within the time constraints.
• As part of a very limited development team, I collaborated with other engineers, technical staff, and SME's to build solid server-side and presentation-layer frameworks primary technologies were JDK6 and jQuery, respectively . Requirements dictated that the tool be highly customizable/configurable, highly skin-able, and easily expandable to accommodate future requirements and general unknowns . The product delivered and exceeded expectations. Some observable outcomes: short development efforts to build and expand core functionality, minimal turnaround time to onboard other vehicle brands, a very short defect resolution time, and more.
• Created a re-usable Java library for core business functions that was leverage by other teams these libraries included such things as web service consumer APIs, core platform APIs, common utility packages, etc .
• Created a JavaScript test-bed with jQuery and the QUnit testing framework to cover all JavaScript libraries components, widgets, framework code, etc . Achieved solid 90 code coverage on all code-bases.
• Created and maintained a common build process using Maven and Jenkins to automate the building and deployment process, as well as to spin up and enable a collaborative dev and Continuous Integration environment.
• On-boarded and coached junior developers who participated in the project and set them up to be able to most effectively contribute towards the application removed obstacles and unimportant nuances from their field of vision
• Used JMeter to performance test the server-side application and services. Applied high volume to put pressure on the system, and measured critical performance criteria such as threading, response times, synchronization, server state, and more.
• Used JProfiler to monitor and identify memory leaks and performance bottlenecks in the server-side application.
• Worked with QA department to resolve defects and identify flaws in the development/testing process at the same time. Testing cycles were very short-spanned and aggressive, so close communication and collaboration was the key to success.
• Result of testing process was a low Defect Density Ratio of 12 a key QA reporting metric , which could be attributed to an expansive unit test library.

Confidential

Senior Java Developer

• Designed and implemented a flexible and configurable benefits administration website using Struts 2 framework with an Oracle back-end. Used many design patterns including Facade, Bridge, and Singleton. jQuery JavaScript framework and many off-the-shelf jQuery plug-ins were used in the presentation layer, as well as CSS2.0, to provide a dynamic and exciting look and feel to the front end, in what would be an otherwise static-looking website.
• Experienced single-handedly building an application from scratch, with full control of all design decisions.
• Wrote system feeds relying heavily on SQL, utilizing views, PL/SQL packages, and complex Oracle SQL structures to fulfill business requirements.
• Helped upgrade the technology stack to the most recent version, including Eclipse, Tomcat, Single Sign-On framework, and much more. This challenge required the ability to quickly absorb the function and purpose of many legacy applications, and the determination to tackle a plethora of small-to-mid-scale problems encountered while upgrading the development environment.
• Struts 2.x, jQuery, CSS2, PL/SQL, SSO, BIRT reporting framework, design patterns, Oracle, XPath

Title J2EE Application Developer

• Designed and implemented a complex, scalable, highly available transactional data-processing system using SOA.
• Created design documents, object models, database logical model and control diagrams with Enterprise Architect.
• Many advanced technologies, technical tools and programming concepts were used in this project:
• Web Services/SOA
• Inversion-of-Control/Dependency Injection pattern
• Many new features from Java 5.0 packages, such as atomics and the concurrent packages
• Oracle 10G PL/SQL
• A system-wide IoC container that managed the dynamic loading of 'plug-in' libraries
• Utilized XML heavily for system configuration, dynamic metadata, and especially for data processing. All inbound data is converted to a standardized XML format which follows XSDs and uses XML namespaces.
• Engineered a full system monitoring suite which monitored for uptime of shared web services, servlets, and databases, as well as measured disk capacity, thread count, and processor load.
• Per business requirements, designed system to be very generic and configurable platform needed to support new client on-boarding on-the-fly, which meant the ability to process new client file structure, new client-specific business logic, different web services and sequence of web service invocations, and much more.
• Per business requirements, designed system to be hot-deployable no down time was acceptable for deployment of new release, or new client on-boarding.
• Wrote persistence framework for back-end using PL/SQL integrated with the common company data-processing libraries.
• Delivered system ahead of time with low defect density ratio.
• This project was a smaller project, requiring a heavy-duty batch-running Java program to process a large amount of data very quickly.
• Studied requirements, held many design sessions with co-developer to address all possible performance problems before starting to write any code.
• Wrote application using many re-usable company libraries, decreasing time as well as defect risk.
• Pair-programmed during the initial implementation phase.
• After program was written, installed and ran some eclipse plug-ins to determine important characteristics about the program, such as JUnit code coverage using EMMA , hidden defects using FindBugs , and circular-dependency tracking using the Metrics tool from metrics.sourceforge.net .
• Evaluated program performance and re-factored code to increase performance, efficiency, and decrease overhead and memory footprint.
• Wrote Jasper reports to show program results after it completed writing to the database.
• Installed the Subversion tool, and helped evaluate its potential use as a version control back-end for company-wide use.
• Led a company-wide initiative to form a standard build-process strategy to be followed by all active and planned projects. Wrote custom Ant tasks as part of this effort. Part of the functionality of the new common build process was the area of dependency management which is basically what Maven is well known for doing.
• The new build process enabled component re-use, and had to be designed in such a way as to allow for the seamless integration of a start-up open-source development model that the company was initiating.
• Helped evaluate the new company Community Development Environment CDE tool, GForge, which led to the purchase and in-house installation.
• Designed and constructed software while adhering to the Software Life Cycle methodology according to CMMI level III, as well as ISO 9001 processes both which are company standards .
