Senior Developer

Bowman Systems develops and markets the world's most trusted, secure and comprehensive Web-based social services software, including its flagship solutions, ServicePoint™, CommunityPoint™ and HousingPoint™. It provides a full suite of software products and services to the Health and Human Services industry. It has clients in over 3000 agencies, 175 jurisdictions, and 40 states. ServicePoint™ (SP) is a revolutionary, web-based application empowering human services providers, coalitions, and communities to manage real-time client and resource data. ServicePoint provides robust client and referral tracking, case management, agency/program indexing, and reporting through a web interface. 

Responsibilities:

·   Integrated Business Objects XI Web Intelligence (BO) reporting tool to SP to meet the reporting needs of the clients. Worked on BO SDK (Java) to migrate the Users in SP to BO and set security to Users, Universes, Universe Connections, etc. Modified existing Java, struts, and JSP BO XI web application files at the Tomcat server to suite our requirement.

·   Modified the BO XI Servlets files in struts framework to function according to our requirements. Added additional Servlets in struts framework to add extra functionality.

·   Designed and developed Java based Rights Migration automation tool (RAT) to run the steps involved during migration process of warehouse build. Used Eclipse as the IDE and ran ANT to compile and run the code.

·   Designed XML specification for custom rights input parameters for RAT using XML Schema. Used Java SAX parser to parse the xml file and convert into a custom DOM tree.

·   Used log4j for logging activities, and Apache ‘cli’ for parsing command line arguments.

·   Used Java ‘processes’ to execute the intermediary steps in the RAT.

·   Used ANT to compile, build, deploy and execute the Rights Migration Tool (RAT).

·   Design and developed JSP and Servlets on BO XI end to perform activities like single sign-on, etc.

·   Changed the BO XI Java files (Java, Servlets, JSP files in Struts frame work) to implement custom requirements.

·   Added/changed Tomcat’s configuration (web.xml) to deploy/initialize Servlets/JSP. Changed Tomcat’s server.xml to support https and to restrict access to BO XI administration from outside world.

·   Used MS-SQL ‘bcp’ tool to dump the data as specified in the ‘bmp’ format file for faster data import into the warehouse database (POSTGRESQL).

·   Speed enhanced SP. Reduced the page response times of important pages of SP from 10-15 seconds to around 3-5 seconds. This was done by re-writing PHP control flow where appropriate to increase speed of execution.

·   Used JavaMail to manage emails (error handling and notification) in the RAT tool.

·   Rewrote SQL procedures and function for query optimization and speed execution. Added indexes where appropriate for faster access (clustered and non-clustered).

·   Developed ScanPoint module, which uses bar code scanner for faster client lookup, using FPDF writer (php module for creating pdf documents).

·   Used ‘phphtmllib’ for modular html creation in PHP files.

·   Developed modules of SP like RidePoint: module for scheduling vehicles, AAA: module for state based Area Ageing and Administration.

·   Designed and implemented MS-SQL database tables, triggers, stored procedures, functions, and views.
