Vision AI:• Enhanced the Vision AI project by enabling image capture and transmission. Utilized ESP32 as the slave and NRF as the master controller. Enabled ESP32 to capture images on NRF's request and transmit them to NRF via UART. Facilitated NRF's transmission of images to the server using LTE-M over UDP.• Integrated direct image transfer to a UDP server over WiFi from the ESP32 controller, enhancing project functionality with seamless transmission of captured images.• Implemented image transmission via Secure MQTT over LTE-M, enhancing project capabilities with encrypted communication for seamless and protected image transfer.• Implemented unit test cases to validate camera configuration and image capturing functionalities, ensuring robustness and reliability within the Vision AI project.• Implemented functionality in CLI mode of device for configuring parameters of the slave (ESPP32) in the Vision AI project, allowing modification of Slave's parameters e.g server and WiFi credentials etc. Successfully addressed the challenge of concurrent UART usage between ESP32 and NRF for CLI traces, achieving seamless functionality without an operating system.• Developed a pipeline to fine-tune a pretrained AI model, converting it to TFlite mode, and optimizing I It with quantization. Transformed it into a C array format for seamless integration with microcontrollers, enhancing functionality in the project.BrighterBins:• Developed an EEPROM management module using parameter IDs and dynamically assigned addresses for efficient firmware updates. Seamlessly handles parameter addition and deletion, eliminating hardcoded addresses and padding issues from older versions• Implemented EEPROM encryption to secure device parameter data, ensuring confidentiality and I Integrity.• Implemented UDP-based downlink over LTE-M for remote device parameter configuration, enhancing flexibility and accessibility.

I worked on Prepaid Smart Energy Meter is capable of providing electricity only forthe prepaid amount, Detects Electricity stealing. It can also interactwith the users through GSM, payments are done directly to the meterusing the user’s RFID Card, and that RFID card could be recharged byusing any bank application. My Contributions were ComponentSelection, Circuit Design, PCB Design, Programming, and SensorsIntegration
