PAK-EL LAB takes hardware projects from schematic to shipped product — PCB design, embedded firmware, mobile apps and connected devices for industrial, marine, automotive, wireless and research applications.
Hands-on circuit, firmware and product development experience.
PCB, firmware, IoT and mobile apps under one team.
Remote collaboration across countries and time zones.
NDA-friendly, with project files kept confidential.
PAK-EL LAB is an electronics engineering studio built around four core disciplines. Each one has a dedicated page covering scope, deliverables and the technologies involved.
Schematic capture, PCB layout, BOM, Gerber files and manufacturing-ready hardware for embedded and IoT products.
C/C++ firmware for ESP32 and STM32-class hardware — drivers, communication protocols and application logic.
Wireless-connected products — LoRa, UWB, BLE, Wi-Fi and cellular hardware paired with cloud dashboards and mobile apps.
Rugged embedded systems for process instrumentation, vehicle electronics and shipboard monitoring.
Also available: Website Development, Addressable LED Systems and Sound Apps & Smart Watch Systems — see the full services list for scope and deliverables.
Engineering support for marine, automotive, oil & gas, industrial automation, consumer electronics, wireless communication and research prototypes.
A mobile app, ESP32 gateway and remote LoRa node communicating in real time with no internet or SIM card — including custom PCB design, OLED display support and battery-powered operation.
Production-ready circuit boards for embedded systems and product prototypes.
LoRa, ESP32, UWB and sensor nodes for remote monitoring.
Sensor monitoring, control boards and firmware-driven automation.

I had no knowledge of PCB design and Tahir helped me realize my project and has set me up for ordering the actual parts I need, recommend.
Great work. He suggested improvements and went beyond what was expected. He answered all my questions and provided communication all the time.
Tahir did an amazing job with my ESP32 project! The code worked flawlessly, and his demonstration made everything super easy to follow. Definitely one of the best developers I've worked with.
Tahir provided exceptional ESP32 programming services. His expertise and attention to detail ensured that my project was completed flawlessly. He was very responsive, professional, and delivered ahead of schedule.
The schematic I received was exactly what I needed — clean, accurate, and well-organized. All components were properly labeled, and the design was ready for PCB layout without any issues.
Tahir's work in Electronics Engineering truly impressed me with his professionalism and exceptional attention to detail, far exceeding my expectations. His ability to clearly communicate complex concepts made this outstanding.
Tahir did a great job laying out my PCB. Was very responsive and professional.
Really nice and friendly guy, helped me understand a lot of things and problems I was not or partially aware of, and helped me even before actually starting the job. Easy and quick communication.
Working with ahmaduzair71 was a pleasure. They are not only skilled in PCB design but also dedicated to customer satisfaction. I highly recommend their services and will definitely be returning for future projects.
