Project: Next Generation Primary Display (NGPD)

The NGPD is a graphic monitor utilizing an 8-inch LCD display. The intent of these displays is to operate as the primary display unit (PDU), e.g. Main monitor, instrument panel, gauge cluster, at a specified target value. Display content will be supplied via Ethernet or CAN; discrete inputs are not used (e.g., tank levels will not be wired to the display, but broadcast via a CAN message from another controller).

At the start of production, the NGPD will have an im6DualLight running a Yocto-based Linux distribution with 8 GB of eMMC flash and TBD DDR3 RAM.

Environment and tools: QT C++, QML, QTWidgets, Gtest framework, VS Code, VSpy3, PhoenixUtility2, sqlite3, GitHub, Jenkins, CPPcheck, Linux.

Responsibilities:

• Implemented an embedded UI application for construction vehicles using Qt/QML.
• Developed tell tales, diagnostics menus, and counters features for various construction vehicle models.
• Collaborated with cross-functional teams to ensure seamless integration of new features into existing product lineups.
• Provided comprehensive aftermarket support for construction vehicles, ensuring optimal performance and customer satisfaction.
• Collaborated with clients to troubleshoot issues, deliver timely solutions, and contribute to enhanced vehicle longevity and reliability.
• Mentored junior engineers, contributing to their professional growth and overall team productivity.

Client: Welbilt

Project: Embedded IoT Application

The Welbilt KitchenConnect project is a premier digital solution for a new generation of connected kitchens. KitchenConnect provides remote access to real-time data generated by the customer equipment, so the customer can monitor their operations to improve their workflow, food quality, and oven maintenance to limit downtime. The gateway board is used to interface with the controller board to collect raw data. The Gateway board has embedded Linux running on it. Collected raw data will be framed as a JSON message and published to the cloud.

Environment and tools used: C, C++, Qt, VS Code, SQLite3, GitHub, CPPCheck, Linux, AWS IoT, and AWS S3.

Responsibilities:

• Designed a JSON specification and a high-level design document.
• Developed an IoT application to exchange data between the AWS cloud platform and Azure Sphere hardware.
• Developed a TCP/IP application to exchange JSON messages between Azure Sphere and the connectivity board.
• Code was reviewed, and feedback was provided to peers.
• Coordinating with onsite and offshore teams for support and guidance to the team onsite.

Project: RADAR tracking application.

RVRAT is a high-speed data recorder that can record the data coming from three different interfaces and send the same data to the PSP system. These interfaces may be a PCI-based NI-DAQ 6534 card, Ethernet, and a PCI-based sFPDP card (SL240) interface. The data received from these interfaces was filtered, compressed, and then logged into a storage device. RVRAT will receive the commands from the web-based GUI and run accordingly. RVRAT also sends its status information to a web-based GUI every 5 seconds. This information contains available disk space in the storage device, elapsed time, filtering on, and filtering off.

Environment and tools used: C, C++, MS Visual Studio, and SVN.

Responsibilities:

• Software development for the reception of data from the PSP and sending processed information to the Analog Display using UDP socket programming.
• Development of a real-time setup for interface with PSP and analog display software for unit testing of modules.
• Development of a GUI for extracting and filtering data recorded by the Radar Video Recorder and Analyzer Tool (RVRAT).
• Software development for the reception of data from the NIDAQ 6534 card.
• Software development for the reception of data from the SL240 card.
• Sending channel status information to a web-based GUI using UDP socket programming.
