Hardware Diagnostics & Validation Engineer | Embedded Systems (STM32) | PCB Debugging | IoT & Automation

About

Electronics & Communication Engineering graduate with hands-on expertise in Embedded Systems, IoT, Hardware Validation, and Electronics Diagnostics. I have strong practical experience working with microcontrollers (STM32, GD32, Arduino, NodeMCU), multi-layer PCB line tracing, sensor calibration, and telemetry systems across both Commercial Robotics (Mukunda Foods) and Meteorological Instrumentation (Electro Mechanical Enterprises). Key Technical Highlights & Practical Experience: Commercial Kitchen Robotics (Mukunda Foods): Led hardware diagnostics, commissioning, and system testing for 100+ automated robotics units (Dosamatic, Wooky, Eco Fryer, Eco Griddle, Deck Oven, Oil Filtro, etc.). Hardware & PCB Diagnostics: Skilled in component-level troubleshooting, multimeter circuit tracing, display driver testing (ST7789/ILI9341), and firmware flashing using CubeIDE and ST-Link. Environmental Sensors & Instrumentation (Electro Mechanical Enterprises - 10 Months): Installed, tested, and calibrated 30+ Disdrometers, 10+ Automatic Weather Stations (AWS), 50+ Pyranometers/Pyrgeometers, and 5+ Sound Level Meters. Telemetry & Data Integration: Configured and integrated 50+ Data Loggers and set up remote monitoring networks using 20+ Modems/Routers (GSM/GPS). Manufacturing & Assembly: Designed and manufactured 20+ Armature Growler Testers from scratch for electrical diagnostic testing (short circuit and coil defect detection). Technical Skills: • Hardware & Testing: PCB Diagnostics, Circuit Line Tracing, Multimeter Debugging, Hardware Validation, Root Cause Analysis (RCA). • Microcontrollers & Tools: STM32, GD32, Arduino, ESP8266/NodeMCU, STM32CubeIDE, ST-Link. • Protocols & Connectivity: SPI, I2C, UART, RS232/RS485, Data Loggers, GSM/GPS Modems. • Programming: C, Embedded C, Python. Open to career opportunities in Embedded Systems, Hardware Testing/Validation, IoT, Electronics Engineering, Instrumentation, and Automation.
