Smart Automation Gateway project

• Developed dual-UART firmware architecture on ESP32-S3-WROOM-1 to enable reliable RGB lighting control and concurrent communication with multiple touch boards.
• Implemented centralized device control firmware on ESP32-S3 to manage multiple touch interfaces and RGB lighting modules.
• Designed and validated TCP/IP device control communication using Hercules and Docklight for debugging.
• Developed ESP-IDF, FreeRTOS and C firmware for ESP32/ESP32-S3 controllers used in home and commercial automation products.

ESP32 Motor & 8-Channel Scheduling Controller using ESP-IDF, FreeRTOS, UART, NVS

• Built UART-command firmware to control a motor and 8 channels/switches individually using ON/OFF, reset, manual and scheduling commands.
• Created user-defined scheduling where the user can set motor/channel timing, selected outputs and operating sequence without changing firmware code.
• Added flow-sensor safety logic: if water flow is not detected during a schedule, active outputs are turned off and the schedule pauses until reset.
• Used NVS state storage so an interrupted schedule can resume from the stopped step after reboot or reset command.

ESP32-S3 Touch LCD 2.8C Display Control System using Touch UI, Home Automation

• Developed touch-board/display control firmware features for commercially installed automation panels used in client homes and commercial spaces.
• Enabled SD card support for display assets/configuration and improved control behaviour for curtains, RGB lights, tunable lights, dimmers and fans.
• Structured display control flow around home automation loads, device selection and command response from the touch interface.

Quality Assurance Automation Testing Intern at Pepperl+Fuchs India Pvt Ltd (2025-02 – 2025-05)

• Performed QA testing on 50+ sensor batches weekly using multimeters, encoder kits and calibration tools, ensuring compliance with required standards.
• Configured and calibrated sensors using PACTware and Sonprog; verified IP settings and client-specific communication requirements through Docklight.
• Documented test results for 200+ sensors monthly and reduced repeated quality issues by 20% through better validation records.
• Collaborated with engineering teams and applied workshop inputs to improve sensor testing and calibration workflow.
