Hire the Best Embedded Systems Engineers
in Pakistan

A founder once told me his last firmware hire "got it working on the desk." Six months later, 200 units were in the field dropping BLE connections, crashing on low battery, and missing sensor reads. I was brought in to fix it. That is the situation I help you avoid. I write embedded firmware in C/C++ for STM32, ESP32, and nRF52. RTOS-based, power-optimized, documented. Built to survive the field, not just a demo. ◆ Core skills: • Embedded C/C++ — bare-metal and RTOS (FreeRTOS, Zephyr) on STM32, ESP32, nRF52 • Wireless protocols — BLE, Wi-Fi, LoRa, MQTT for connected IoT devices • Power optimization — deep-sleep sequences, battery management, USB-C charging • Sensor integration — I2C, SPI, UART, HX711 load cells, MEMS microphones, IMUs • PCB-aware firmware — signal integrity, DFM-conscious bring-up, hardware debugging • Clean handoff — documented, version-controlled, ready for your next engineer ◆ Shipped products: • BLE lapel microphone — MEMS arrays, haptic feedback, USB-C charging on nRF52 • IoT waste bin monitor — HX711 load cell, MQTT cloud streaming on ESP32 • Wearable LED therapy cap — multi-wavelength PWM array control on STM32 • LoRa/GPS/BLE asset tracker — compact multilayer hardware, full firmware stack • Automotive IoT power supply — 12V robust embedded control with deep-sleep optimization ◆ Tools and platforms: STM32 · ESP32 · nRF52 · FreeRTOS · Zephyr · Altium Designer · KiCad · BLE · Wi-Fi · LoRa · MQTT · I2C · SPI · UART · USB-C · Embedded C · C++ · Python · Git 🎯 Who I Work With I work best with founders and engineering leads who know that cutting corners on firmware costs more later. Good Fit: • You have a real product going to market — not a prototype that lives in a drawer • You come with defined requirements: target MCU, protocol, specs, or a reference schematic • You are available for milestone check-ins — firmware is iterative • You understand good embedded work takes a realistic timeline Not a Fit: • University assignments or thesis work — I only take commercial projects • You want BLE "just working" without caring about stability or power draw • You need a full firmware stack delivered in two to three days 🏆 Track Record 90% Job Success · Top Rated · $30K+ earned · 700+ hours delivered Book a consultation above or send an invite, happy to look at your project.
