About Me
I am a resourceful and passionate software engineer of 20 years. I have experience architecting both public and internal service oriented applications and finding creative solutions to complex problems. My role has broadened over the years to include general infrastructure and cloud architecture. I’ve had the opportunity to work closely with data engineering and data science teams, and have a working knowledge of data pipelines, machine learning and big data. I have a specific interest in high-performance, real-time applications. Some of my most recent work has been with Golang and Kubernetes.

March 2013 – April 2014
- Co-Creator of the Nestivity product platform.
- MongoDB persistence with Spring Data
- Hazelcast for caching and inter-node communication
- Sole author of the Muncher platform
- Muncher is responsible for handling and processing a syndicated Twitter firehose in conjunction with the Twitter public API. Currently storing 25K tweets a day
- Hazelcast for internode and interprocess communication allowing for long polling, data deduplication, and Nestivity platform synchronization.
- Implemented an automated build and test workflow with Maven, Jetty and Jenkins.
- Completed work on the first customer release of the Android mobile offering, supporting communication with the existing platform API.
- Brought expertise in re-architecting the current platform.
- Collaborated with development team members on the design and implementation to overhaul the current platform.
- Supported existing maintenance efforts with the current platform.
- Developed and maintained software applications such as the MoveMeter, Repair Parts Database, and Utilization applications; that were used by internal manufacturing and engineering departments.
- Converted source code control from MS Visual SourceSafe to CVS.
- Optimized the existing Engineering Database to achieve a 25% increase in capacity, and implemented automated data loading and monitoring.
- Developed and implemented multiple award winning applications such as the Equipment Management Control Panel, which was instrumental in the efforts of a factory-wide tooling conversion; as well as the Problem Lot Disposition system, which played a key role in identifying, containing, and correcting issues on the production floor.
- Administered 8i, 9i and 11g Oracle database instances housing approximately 40 schemas. Successfully migrated existing 8i and 9i instances to a 2 node 11g Oracle RAC environment.
- Effectively transferred existing Unix/Linux systems to a new hardware and operating environment. The environment was constructed to maintain high availability by using various clustering and virtualization technologies. Linux Virtual Server and RedHat Cluster Suit were introduced to the native Apache and Tomcat solutions for clustering and load balancing.

Awards
Award for Exceptional Performance
2010
Received the award for Exceptional Performance for the development of the Equipment Management Application. The application was critical in coordinating the effort of a 4 to 6 inch substrate conversion on the factory floor. The application also provided enhanced user control of equipment configuration in the manufacturing execution system(MES). This application was mentioned in the July 2010 issue of Compound Semiconductor, Back to GaAs Roots, pg. 30.
Award for Exceptional Performance
2004
Received the award for Exceptional Performance for the development of the Problem Lot Disposition System. The Problem Lot Disposition system is currently used in all front end manufacturing in plants including Newbury Park CA, Woburn MA and Mexicali Mexico.
