- Architect, design and code device software (Python on Raspberry Pi OS Lite) for IoT smart barricade and custom Zigbee gateway. Firebase/Google Cloud Platform (GCP) REST back-end; Flutter front-end.- Hardware validation and software support for production prototype Raspberry Pi CM4 carrier board.- Harden smart barricade engineering prototype by improving reliability of device (Python on Debian) and securing/expanding server (LAMP, Mosquitto MQTT server deployed on AWS).- Advise executive management on Engineering organization, DevSecOps, cloud infrastructure, external software and hardware development partners, customer engagement and proposals.

- System design support for new SaaS cloud-based device management solution. Application, platform, and DevSecOps pipeline represent an archetype of next generation radio system infrastructure.- Advised internal and external customers on key management products, encryption and Over-the-Air Rekeying (OTAR) for radio systems. Supported teams with FIPS 140 validation efforts.- Practiced Agile Scrum as scrum master and scrum of scrums facilitator.- Operated in diverse application spaces including key management, device management, activity reporting, dispatch, location, administration and network management. Technologies included C#, C++, C and Java running on Windows and Linux; SQL Server, SQL Replication and SQL Reporting Services.

- Managed multiple application teams including two offshore teams.- Oversaw application areas including key management, device programming, provisioning and activity reporting. Technologies included C# and C++ running on Windows; SQL Server, Microsoft Cluster Service and SQL Reporting Services.

- Guided design, development, enhancement, fielding and support of multiple key management solutions ranging from server-based network key distribution to manual, direct-connect and interoperability enablers. Code primarily written in C# with some legacy C++ on Windows platforms.

- Directed implementation and fielding of Key Management Facility (KMF). The KMF is a hybrid Windows server application (C#/C++) enabling secure distribution of symmetric encryption keys to radio system devices.

- Gathered requirements and led design of Key Management Facility.- Delivered C# Fault Monitoring Service and SNMP sub-agent for Windows XP Embedded.- Created user-friendly wizards to simplify common key management tasks using C# and Syncfusion GUI components.

- Improved product quality and performance by increasing scope and complexity of test environment while formalizing change control, build and QA procedures.- Designed and coded C# fault tolerant OPC module for mission-critical plant floor operations.

- Researched, designed and developed distributed C# trading systems for financial markets.- Led five-member team in implementation of C++ third-tier B2B application for Windows Server.
