As a Staff Software Engineer for Synapse Wireless, I've had the opportunity to be involved in the architecture, design, implementation, and maintenance of a number of cloud based services and applications in the lighting and energy management industry.One of my earliest development projects at Synapse involved working with a small team in 2015 to build and launch Synapse's first successful cloud based software service, SimplySnap Remote Access (SSRA). This service is still in use today by many of Synapse's customers, and provides them with a web based portal into their on-premises site controllers for lighting management. The application itself is a straightforward AngularJS web application, running ExpressJS on the server side. I introduced the practice of Infrastructure as Code (IaC) to Synapse during the development of this product, employing Terraform to manage our Amazon Web Services (AWS) resources in a controlled and reproducible way. We also use SaltStack for configuration management of the EC2 instances for SSRA, and the application servers run inside Docker containers.I am currently working with another small team to develop SimplySnap Cloud, Synapse's premiere cloud based platform for lighting and energy management. We began designing and building SimplySnap Cloud in 2018, using several of the lessons learned from the development of SSRA to accelerate the process. As was the case with SSRA, we use Terraform to manage the AWS resources for SimplySnap Cloud and SaltStack to manage the configuration of its EC2 instances. The platform software is a combination of Dockerized services and “serverless” services that run on the AWS Lambda service, and we use a number of AWS managed services, including DynamoDb, RDS, Firehose, and OpenSearch, to supplement the SimplySnap Cloud platform software. Unlike SSRA, SimplySnap Cloud is a more modern Angular web application, running Apollo Server on the server side to serve up SimplySnap Cloud's GraphQL API.

As a Program Manager (PM) for deciBel Research, supporting the Tactical Airspace Integration System (TAIS) project for the Software Engineering Directorate (SED), I was responsible for managing the relationship with our government customer and ensuring that our team members delivered high value to that program. This included working with the customer to understand his needs for the SED-TAIS program, finding new opportunities for deciBel Research to contribute to the effort, working with our contracts administrators to ensure coverage for team members, and conducting performance evaluations for team members.In addition to my responsibilities as PM, I led a team of five developers in the development of the Airspace Web Services (ASWS) for TAIS. The goal of this effort was to deliver a RESTful web-based API for TAIS that could be used by a variety of browser-based and mobile clients. The software was implemented in C#/.NET, using Microsoft's ASP.NET Web API framework. Our use of an agile software development process ensured high visibility into our progress for our customer, and enabled a tight feedback loop as the software evolves.Previously, as Software Team Lead for the Enhanced Airtrack Sensor Interface (EASI) user interface, I led a team in the delivery of two major releases of this new product for the Army. EASI is an application used to configure, manage, and monitor links between TAIS and remote airtrack sources (e.g. radars and other sensors). The software consists of a web-based UI implemented using AngularJS; ASP.NET on the server; and back-end integration with the TAIS, SATIN, and KABIC systems for airtrack data analysis and fusion. Prior to that, as Program Manager for the Virtual Receiver/Exciter (VREX) Phase I SBIR project, my responsibilities included managing project resources, maintaining positive communication with our Government customer, and generally ensuring that we met our contractual obligations.

Implemented support for the OMG CAD Services Specification V1.0 in CFD-GEOM, CFDRC's geometry and grid generation application. This effort included the integration of CFD-GEOM with the Open CASCADE platform for 3-D modeling and simulation.Additionally, while there I developed both CORBA and Python scripting interfaces to CFD-VIEW, CFDRC's 3-D data visualization application, and developed and integrated 3-D visualization capabilities for their CFD-CADalyzer application.

Worked with a small team to design and develop Pathways, a software application for DNA microarray analysis. Developed and refined software engineering processes for the Bioinformatics department. Developed automated procedures to maintain bioinformatics databases at ResGen. Developed core EJB libraries for bioinformatics data services (BIDS) project, used by Java web application developers.

Huntsville, Al, Us

Coordinated graphical user interface (GUI) development for CFDRC flow solvers, as well as several related aspects of commercial software product management (e.g. maintenance and quality assurance). Served as product manager and lead developer for the CFD-ACE+ graphical user interface, and directly supervised two other software engineers on this project. Instructed junior developers in topics such as object-oriented analysis and design, portable C++ programming, and porting applications from Unix to Microsoft Windows. Presented in-house technical seminars on GUI development and Defensive Programming Practices.
