About

Final-year Electronics & Communication Engineering student with hands-on experience across PCB design, assembly, testing, and embedded systems. Comfortable working from schematic capture and KiCad layout through bring-up, debugging, and firmware development on ESP32 and Arduino platforms.

Experience

• IoT & Embedded Systems Intern
  IIT Madras · Chennai
  Mar 2025 – 2025

  Application-Driven IoT & Embedded Systems Program (10 days). Trained in hardware bring-up, sensor interfacing, and I2C/SPI/UART communication protocols. Programmed ESP32 and Arduino boards for data acquisition, GPIO control, and wireless communication. Took an embedded system from schematic to working prototype with a real-time data pipeline.

• Machine Learning Intern
  Adventure Technology · Coimbatore
  Jan 2025 – 2025

  Built a fake-mail detection pipeline in Python, covering data preprocessing, feature extraction, and model training. Evaluated and benchmarked model performance using standard Python data-science libraries.

• PCB Assembly & Production Intern
  Pioneer Circuits · Coimbatore
  Jun 2024 – 2024

  Assembled SMD and through-hole components and soldered live production boards to IPC-A-610 workmanship standards. Inspected boards visually and electrically to catch soldering defects, component faults, and signal-integrity issues, supporting first-pass yield. Read PCB layout drawings, BOMs, and assembly documentation while following ESD-safe handling procedures.

• PCB Design & Hardware Intern
  Vasantha Advanced System · Coimbatore
  Jan 2024 – 2024

  Worked on PCB design and layout in KiCad, including layout review and hardware validation, in a production electronics setting. Assisted with schematic capture and component selection, checking layouts against DRC and DFM guidelines. Ran hardware bring-up, circuit debugging, and signal verification using an oscilloscope, multimeter, and Proteus simulation.
