  • Take an existing legacy system and re-engineer a modern and reliable replacement. The new system is using Spring MVC (4+), Apache Tiles (3.0.5), and Spring Security (3.2) for the web application, as well as jQuery UI (1.11+) and jQuery DataTables (1.10+). Accessible via both REST and SOAP (JAX-WS) web services. Produces reports as well as ingesting new data using Groovy scripts. The system is running on virtual servers, similar to Amazon EC2.

09.2004 - 09.2014
  • Designed and developed NightSurf, a role-based system that allows users to run metrics, reports and ad-hoc queries against a large Oracle database. NightSurf’s ad-hoc query capability is used when no other tool can answer a user’s question. It allows users to schedule re-occurring queries to re-run at given intervals; this is accomplished using Quartz, a job scheduling framework. It also allows users to retrieve extremely large data sets, because it streams the results thru the system. The system allows both user and administrators to cancel problem queries. NightSurf uses Spring Security to accomplish single sign-on via Public Key Infrastructure and Spring MVC to manage workflow.
  • Designed and developed Banyan, and its sub-systems to include various Enterprise Java Beans (EJB 3+ compliant), Message Driven Beans (MDB), Authentication Service, Web Services (JAX-WS and REST), and Web Application. Banyan is a federated system that allows a user to query multiple databases with one query. Built into Banyan is a throttling mechanism, which is a property file configurable to allow a server to throttle the number of queries it runs at time. This throttling mechanism also allows Banyan to throttle the number of queries any single one user is running at any time. This keeps a single user from using up all system resources, making the system unavailable for other users. If a server is restarted, any queries that were running are automatically restarted. Banyan is a scalable system; new servers can be started when more resources are needed. it uses Spring Security to accomplish single sign-on via Public Key Infrastructure and Spring MVC to manage workflow.
  • Designed and developed Dishfire, using Enterprise Java Beans (EJB 3+), Message Driven Beans (MDB), Authentication Service, Web Services, and Web Application. Dishfire uses Spring Security to accomplish single sign-on via Public Key Infrastructure and Spring MVC to manage workflow. Dishfire queries multiple identical databases and combines the results into a single data set. The design of Dishfire allows the team to add more databases if needed, with very little code change. Dishfire also has the same throttling system built into Banyan.
