Lead a team of 4+ engineers in the creation of New Project Initiatives (NPI) that leverage Zigbee and Silicon Labs EFR32MG ARM microcontrollers.Carry out board bring-up activities for customized boards equipped with MCUs, UART, SPI, and I2C connectivity for various drivers and sensors.Create and document memory architectural layouts to ensure NVM and over-the-air (OTA) functionality.In conjunction with cross-functional teams, design, plan, test, and deploy lighting control devices within system releases.Using Jira, keep track of problems and resolutions on a daily basis.Bamboo can be used to manage CI/CD for the company's fleet of wireless node devices.Improve business performance by directing and assisting with Quality Assurance teams.Provide technical assistance and leadership to members of the development team, as well as educate them on essential design decisions and procedures.

Lead a team of 3+ engineers to create New Product Initiatives (NPI) that use Zigbee and Silicon Labs ARM microcontrollers (MCU) for lighting control systems with multiple communication interfaces to LED drivers.Lead developer of a lighting control system that runs a light-weight machine-to-machine (LwM2M) client with Datagram Transport Layer Security (DTLS) on a FreeRTOS.Lead developer for a Bluetooth Low Energy (BLE) firmware project aligned with Eaton's Internet of Things (IoT) strategy to increase connection, energy efficiency, operation efficiency, and send regulatory test findings to a mobile application.Using the Atlassian Product Suite, I delivered projects and continuously enhanced software processes based on the scrum framework and agile methodology (Bitbucket, JIRA, Bamboo, and Confluence)Collaboration with diverse teams to develop interface needs between hardware and mobile applications, while guaranteeing thorough, precise, and deliverable product specs

Exhibited independence and excellent technical judgment in identifying challenges and developing solutions for the flagship CT scanner platformJunior team members received technical coaching and leadership on design and development.In charge of designing and developing real-time processes (RTPs) and device kernel modules (DKMs)Maintaining a proprietary C/C++ platform for boot control subsystems for the e500, MIPS, and ARM architectures.

Created Python scripts to automate testing scripts and Real Time Processes (RTPs), Downloaded Kernel Modules (DKMs), and debugging tools for the VxWorks RTOSImplemented software to aid in cost-cutting initiatives for a variety of Inventory Carry Value (ICV)/Variable Cost Productivity (PVC) New Product Initiatives (NPI)To perform static analysis and code reviews, I used Coverity and Code Collaborator, respectively.IBM Rational ClearQuest and HP's Application Lifecycle Management were used to support formal verification methods and software defect management (ALM).

Agile development methods were used to generate C/C++-written firmware for a platform running the eCos RTOS.Developed diagnostic tools and low-level drivers for a New Product Initiative (NPI) PET scanner that tracked environmental conditionsDeveloped a number of VHDL modules for reset logic, as well as tested and validated a variety of interfaces for bespoke control boards.TCL scripts were written for the NIOS II System Console to evaluate I2C commands for hardware to perform read/write operations on flash.

In VHDL, I designed a host serial interface module (UART) for a complex programmable logic device (CPLD) on a diagnostic control board for a future MRI scanner.ModelSim was used to develop massive simulations and detailed test benches for FPGA and VHDL systems.Lead talks for early design concepts for CPLD and FPGA designs with teams in China and Japan to reduce system reset time and provide a method to discover system problems for a New Product Initiative (NPI) platform.CPLD specifications were developed and recorded, and verification was performed in accordance with engineering design methods.Engineering Change Order (ECO) and Engineering Change Request (ECR) processes were completed for equipment entering the end-of-life (EOL) phase.

Extend a Linux-based C++ project that investigated wireless packet loss between wireless cardiac monitors and wireless LAN (WLAN) controllers.To assess the wireless capabilities of the devices, RF isolation cambers, WLAN controllers, and Cisco access points were used.Developed C++ code to automatically perform wireless testing of a unit under test (UUT) in accordance with Design Verification Procedures, saving 70 manned-labor hours for testing and formatting results.C++ code was written to coordinate and transmit commands to a Cisco WLAN controller, Cisco APs, and a UUT.

Implemented an image thickening algorithm written in Matlab/Freemat for the Revolution CT scanner, resulting in better image quality than the existing base CT system.Created code and scripts that performed automated quantitative analysis on images produced by the install base CT scanner vs the new product CT scanner and provided weight coefficients for thick slices automatically.When compared to projection space techniques, image space techniques reduced average image noise by 5% while meeting criteria.

Maintained, evaluated, and repaired problematic equipment Multifunction peripherals from Toshiba Business Solutions (MFP)Assisting Toshiba service professionals in diagnosing faulty equipment in order to preserve service response timeCollaborated closely with IT managers and network administrators to set up network devices to monitor activity and operation.In charge of installing auxiliary hardware and formatting hard drives in accordance with DoD specifications.Used fleet management software to track and arrange MFP machines in preparation for future activities.Improved fleet database (of 200+ vehicles) and monthly invoicing procedures from two weeks to a few days

Conducted a literature review on Artificial Intelligence, Context-Based Reasoning (CxBR), and Neural Networks (NN)Created classes and methods in C++ to improve the learning capabilities of agents for a Contextual Game Observation (CONGO) system in the Visual Studio 2003.NET environment.Conducted research to train and construct agents that behaved like people using CxBR, NN, and observational learning.

A Java-based Field Replaceable Unit (FRU) Parts Catalog (FPC) tool that may be set using XML-based configuration files has been modified.FPC database logistics were expanded, saving the corporation $5 million each year.Developed methods that boost the efficiency of a field engineer, potentially decreasing VCPChanged design implementation to improve visibility and compatibility, making the FPC more platform-agnostic.Added an update function to the FPC that enabled field engineers to get the most recent FRU database.
