About
Need a PCB that passes DRC the first time and is ready to order from JLCPCB? I design 2- and 4-layer boards and write the ESP32/STM32 firmware that runs on them, so you work with one engineer from schematic to working prototype.
What I can do for you:
- Schematic capture and PCB layout in KiCad, EasyEDA or Altium Designer (2 and 4 layers)
- Custom symbols and footprints from datasheets
- Manufacturing files: Gerber, drill, BOM and pick-and-place for JLCPCB or PCBWay
- PCB review and DFM check before you order
- Breadboard or Arduino prototype to a custom PCB
- 3D board model (STEP) for your enclosure design
- ESP32 and STM32 firmware in C/C++ (FreeRTOS, PlatformIO, STM32CubeIDE)
- LTspice simulation of power and analog circuits
Recent work:
- Round 4-layer ESP32-S3 health smartwatch board (PPG, skin temperature, IMU, LiPo charging, haptics) with 0 DRC errors
- Curved 4-layer wearable alarm-band PCB delivered to a client with Gerbers, BOM, pick-and-place, schematic PDF and a 3D enclosure model
- USB-C PD multi-channel power board with STM32 control and current sensing
- STM32 line-follower robot whose main PCB doubles as the chassis (Champion, Auto Grand Prix V6.0)
I am a final-year EEE student at Shahjalal University of Science and Technology, an EasyEDA Official Certified Campus Ambassador and an IEEE EICT 2025 co-author.
Send me your schematic, sketch or idea and I will tell you the layer count, timeline and cost.

Education
-
Shahjalal University of Science and Technology, Sylhet
Bachelor of Science, Electrical and Electronic Engineering
2023 – 2027
(expected)
Activities and Societies:
RoboSUST (Vice President), IEEE SUST Student Branch (Chair), ORCA autonomous underwater vehicle team, EasyEDA Campus Ambassador
B.Sc. (Eng.) in Electrical and Electronic Engineering, expected graduation 2027.
- Focus: embedded systems, PCB design, power electronics and on-device machine learning (TFLite Micro).
- Co-authored and presented Paper PID-747 on ML-based electricity demand forecasting at the 7th IEEE EICT Conference (Dec 2025).
- Research: battery management systems for inverter-based renewable energy and TinyML induction motor fault detection.
Other experience
- Winner - Unibator UIHUB-24 for the ORCA AUV Project (2024) Our ORCA autonomous underwater vehicle project (Dept. of EEE, SUST, supervised by Prof. Dr. Mohammad Shahidur Rahman) won BDT 25,000 funding at the Unibator UIHUB-24 competition organised by Innovation Hub. I work on the electrical stack: power distribution, sensors, thruster control and embedded control.
- Champion - Auto Grand Prix V6.0 Autonomous Robotics (SUST, 2023) My team won 1st place at Auto Grand Prix V6.0, the autonomous ground-pathfinding robot competition at Shahjalal University of Science and Technology, with our STM32 line-follower robot. The custom main PCB doubles as the chassis: 11 IR sensors on a curved front arc, a TB6612FNG motor driver and PID firmware with live sensor calibration. I later mentored the next RoboSUST team to the title.
