Conceptualized/Designed/Implemented various software/signal processing/sensing tools and controllers from project initilization to mass production for 4 different Heated and beverage products in the market. Focused on Ninja brand in heated kitchen applicense and recently working on coffee and water product.

Ninja Nespresso & Coffee/Tea Makers

I am pleased to share with you my experience in developing control systems and algorithms for:

• Ninja Espresso & Coffee Barista System
• Single-Serve Coffee Maker
• Ninja DualBrew Hot & Iced Coffee Maker
• Ninja Hot & Iced XL Coffee Maker with Rapid Cold Brew

which are currently available in the market. From prototype development to mass production, I successfully developed and implemented algorithms (in C++, Arduino, and Python) for all features of the product, including cascade temperature control, flow control, failure detection, altitude calibration, and low-pass filter.

During prototype development, I obtained most of the sensors and AC/DC motor drivers from the market and combined them to model the final product. I then conducted most of the testing on this prototype before implementing the algorithms in the actual machine. As part of my responsibilities, I defined and developed the system flow of the product features and developed testing code (C++, Arduino, Python, and MATLAB) for prototypes. I closely worked with the software engineer to program these features into the final product and documented each feature.

I also identified possible risks and took software-related actions, such as developing error states for the unit and taking real-time actions based on sensor readings. I researched and implemented new ideas/algorithms and approaches to the prototypes and final product and adapted new features in both software and hardware to speed up the research process. Additionally, I supported the testing team and product design team by developing some test software.

Finally, I investigated the root cause of failures and searched for possible solutions. I analyzed the risks related to the failures and proposed solutions to minimize them. I also owned and managed the development of prototype and testing tools, including a Python application and an R-pi/Arduino apparatus to speed up the testing process.

Overall, my experience developing control systems and algorithms for the Nespresso & Coffee/Tea Makers have given me valuable skills in defining and developing product features, testing, documentation, risk management, and troubleshooting.
