Project: Teraview based on POLARIS DB (Province of Ontario Land Registration Information System database), a highly distributed set of server application processes that managed the sales and registration of properties for realtors and lawyers: Implemented a new VM (during personal time) that gave Developers full access to Linux & DB with unlimited disk space, saving up to 10% in time that Developers were previously spending on configuration changes, new library installations, etc., and decreased project build by 7 times Supported and upgraded Teraview back/front end Java/Web servers (Business: Java, ant, J2EE, EJB, SOAP, Web Logic/Data Base: Sybase, Oracle 10g, JDBC/GUI: GWT, Html, CSS, JSP, JavaScript, jQuery, AngularJS) Migrated entire Teraview project from a JDK 1.6 to JDK 1.7. Backed the development of Linux Shell/Python scripts to upgrade passwords on Web Logic server. Identified and fixed existing JUnit tests and created new ones to minimize support efforts. Implemented an AWS/EC2 based VM that gave Developers full access to Linux & DB with unlimited disk space, saving up to 10% in time that Developers were previously spending on configuration changes, new library installations, etc., and decreased project build by 7 times

Project: POS for US Army: Design and implementation POS for US a Designed and applied a Java based TCP/IP multi-threading Credit Server Simulator (XPath based) to support credit card transactions on the POS system, saving QA & Developers ~10% of their time when credit server was down. Hired to identify the best method in migrating POS from B-Tree (embedded DB) to RDBMS, evaluated the proper DB type for it, and successfully completed all tasks. Improved the implementation of Java base VNC multi-windows viewer, allowing the owner to monitor QA tests results in the QA lab. Constructed and executed the POS financial data migration from B-Tree (embedded DB) to MySQL and SQLite (under SUSE Linux).
