Development and maintenance of a sophisticated software system for geospatial data management.Contributed to the MTDA (Mission Tracking Data Analytics) team by developing and maintaining a geospatial data management system, enhancing accessibility for data analytics applications.Leveraged Java microservices and Kafka to optimize data retrieval and storage processes, ensuring efficient integration with multiple repositories.Utilized tools like Eclipse, Toad, pgAdmin, Kibana, Rancher, Hue, Jira and Gitlab throughout the software development lifecycle, facilitating streamlined deployment and effective project collaboration.

Served as a technical lead for the design and implementation of integrated data query and workflow applications.Oversaw the design and implementation of the TSM Query application, improving data retrieval processes through a user-friendly Node.js interface connected to the Total System Model (TSM) REST API. The TSM is an integrated data source comprising multiple disconnected digital models.Developed the TSM Workflow Pipeline Service using Java Spring Boot, enabling effective management and execution of workflow pipelines that query the TSM, validates the returned data, and sends user notifications.Deployed applications in a Red Hat OpenShift containerized environment, streamlining deployment processes and improving application scalability.Managed source code control and build pipelines with Git and GitLab, ensuring version control integrity and efficient collaboration within the engineering team.

Design and develop advanced technology software solutions to resolve obsolescence issues, add capability, improve performance and improve maintainability. Evolve the current ground architecture to leverage newer technologies, facilitate the addition of new systems and reduce Operations & Sustainment (O&S) costs. This effort is focused on transitioning the Telemetry, Tracking, and Commanding (TT&C) and Mission Management (MM) of current and future Space assets to a single ground baseline.

Design and development of a global satellite communication system and its associated operation and maintenance software.Design and development of a global satellite 4G-LTE communication system and the Satellite Access Controller (SAC) component of this system. The SAC is part of the SBSE (Satellite Base Station Equipment).Led a team in development of the HMI (human-machine-interface) component of the OAM (operation and maintenance) software, successfully designing and implementing a Node.js HMI using JavaScript and Redis. Developed the back-end SAC-OAM system using C++, implementing Redis for in-memory data caching and inter-process communication.Utilized PostgreSQL as the persistent SQL database for SAC-OAM components, ensuring reliable data management across applications.Employed Visual Studio Code and Eclipse as IDEs for JavaScript and C++ development.

Development of a command and control system for the operation of Space Vehicles.Developed a Java application to capture streaming telemetry data, perform decommutation of the data and save the data to a Big Data store to be used for subsequent query and analysis. This application uses Cloudera Software’s distribution of Apache Hadoop and their stack of services for processing and storage of the telemetry data. These services include HDFS, Yarn, Kafka, HBase and Spark. Development in C# of a process responsible for managing the state variables available and configurable within the system. The process queries a PostgreSQL database for the static system values and Redis, an in-memory database cache, for the dynamic system values.

Development of a system to manage the operation of Space Vehicles. This included development in Java of a JEE application that processes ephemeris data received from these vehicles. Calculations are performed on this data to determine when vehicles are in view of ground antennas, and other information that may affect the operation of the vehicle. This data is then persisted to an Oracle database.Developed in C# web services to query the database for data used for planning and scheduling of these vehicles.

Research and development of a system for ingesting various types of data into a Big Data Store for subsequent query and analysis. Installed and configured a Big Data cluster for this project within a Linux environment using Cloudera Software’s distribution of Apache Hadoop.Development of a Java application utilizing the Apache Spark API to ingest data into the Big Data store (An HBase NoSQL database).

Development and support of software systems for the origination and servicing of consumer and commercial loans. One is a web-based Java application using IBM WebSphere and a DB2 database. The other is a distributed Visual Basic application using a Microsoft SQL Server database. Both are object-oriented enterprise systems providing workflows for processing loans. Duties included analysis, development and testing to implement new functionality and custom requirements for individual banks.Web Services development.

Design and development of enterprise computer systems for the management of clinical data.Developed front end and middle-tier components using various languages and development tools including Visual Basic, Java, Delphi PL/SQL and Oracle Forms.Projects included the development and support of a workflow system for entry and review of clinical data within the Oracle Clinical environment using PL/SQL, Oracle Forms, and Java. An application for the administration of these workflows using Delphi and various applications in support of a document imaging system using Visual Basic.Developed PL/SQL procedures for systems integration and data warehousing.Project management experience in a Technical Lead role.
