• Beverage/Ice dispensing module: Dispenses pre-selected syrup brands and flavors and dispenses Ice
• Wrote embedded firmware in ‘C’ language on Atmel AVRs (64, 324) for all above sub-systems - that involves motors, sensors, valves, thermistors, etc. Each module communicates to the UI(Master) via RS-485 using Proprietary communication protocol
• Part of the team that developed Commercial Carbonator Unit for Starbucks, to create carbonates drinks, has installation base of 20K units worldwide (Cornelius is a sole provider of this product). This product has LCD screen, and firmware was developed in ‘C’ language for the 32Bit Atmel AT32U3B microcontollers, controls valves, motors, lock solenoids, LEDs etc. Has features like upgrading the firmware from USB, configuring recipes etc.
• Developed firmware in ‘C’ (on 8bit micro-controller, Atmel ATMega64, CodeVision compiler), for a Juice dispensing machine for Starbucks (Cornelius is a sole provider of this product). This product has a Refrigeration system built-in, supported design changes in the firmware written in ‘C’ language ( for Atmel ATMega64, 8 bit microcontroller) for the Refrigeration system
• Developed Dlls in C#, used to communicate with Cornelius control boards(via RS-485) using API calls and UI developed by Pepsi company, for beverage dispensing machines, launched worldwide, with installation base of ~20K units (Cornelius is a sole provider of family of these products)
• Developed firmware in ‘C’ language, for various control modules based on Atmel 8 bit micro controllers for various products at Cornelius, and developed boot loaders to update the firmware in the field. Wrote UI applications for filed updates.
• Developed numerous test applications, in C# (also C# WPF) for R&D work during prototype phase of the projects and those applications helped to analyze the performance, features supported. Implemented lot of automation in those apps that saves hundreds of hours of testing if performed manually and saving a lot of money to the company
• Developed IoT application in C# to demonstrate IoT concept to the business, that application gathers the data wirelessly from Cornelius products and sending that off to the remote server, where it gets displayed on the Web page, SQL data base was used in the project
• Collaborate with team in India, Europe and China, to develop next generation of dispensing machines
• Initiated the project to migrate WinCE (developed in C#) based application to C++, Qt/QML on embedded Linux, added SQL database usage for system data, error loggers, and recipe configuration. Did lot of research and developed test programs in Qt/QML to enhance development skills
• Worked closely with the other members of the project team/external customers, in defining the product requirements, eliminating ambiguity and improving the features of the product, design reviews. Driving engineering change notices.
• Provided extensive field support during all the phases of field trials, interacted with customers directly local and globally. Gathered inputs from the fields in improving the product design. Assisted commercial team with product demonstration and installation on customer site.
• Mentoring other engineers to perform their duties more efficiently, and their professional growth
