Core Competencies
Custom PCB Design
High-precision, multi-layer PCB routing optimized for industrial environments. We ensure EMI/EMC compliance, robust power management, and scalable BOMs for mass manufacturing.
Embedded Firmware
Bulletproof firmware engineered for absolute reliability. We specialize in ESP-IDF, FreeRTOS, secure OTA updates, and low-power sleep state optimization.
Industrial IoT Integration
Connecting the physical to the cloud. Seamless integration with RS485, Modbus, CAN bus, LoRaWAN, and MQTT protocols to AWS IoT or custom web dashboards.
Why GizanTech?
Software is cheap. Hardware is unforgiving.
In an era where AI can write basic web apps in seconds, physical engineering remains a profound challenge. AI cannot solder a prototype, debug a noisy RS485 communication line, or test a soil sensor in the field.
At GizanTech, we are physical engineers first. We build the tangible hardware that your software needs to interact with the real world.
What clients say
4.9★ across 66 projects
Real, verifiable client ratings from hardware teams across the US, UK, EU, and Australia — delivering since 2021.
“I normally do not hand out 5 ratings. In this instance I would highly recommend GizanTech for hardware and software development. They delivered on KiCAD electrical engineering and VSC C code for the PICO with a robust Pi5 C application to test BLE communications with the PICO. Thank you to Masrur and the entire team.”
“GizanTech continue to produce spectacular results for our projects. Looking forward to working with them on many future projects.”
“GizanTech is a very professional outfit. Their documentation was beyond my expectations and their support through the software testing phase was fantastic! If you are new to Freelancer and looking for someone to work with I highly recommend them!”
“Super happy with the effort from GizanTech. The IoT project was well delivered. I had issues when testing the setup on my side but GizanTech remained patient and communicated using easy-to-follow videos and documentation to resolve the issues. Thanks again!”
“He did an excellent job. I am very satisfied with his communication and knowledge; he showed professional knowledge and responsibility. I will work with him again on new projects.”
“Masrur has been a great partner for my latest project. He and his team went over and above my expectations and kept at it until I was satisfied with the result. Communication has been great as well. Very professional. I'm continuing to work with them on future revisions of the project.”
