IoT Firmware Development & Embedded Engineering

@tshibsamuel477

Hi there, I carefully read your profile, and your background aligns strongly with the kind of embedded systems and PCB projects I regularly handle. I’d be glad to collaborate or support your work where needed—especially in areas involving PCB design, hardware validation, or system integration alongside your firmware expertise. I’m Samuel Tshibangu, a mechatronics engineer with several years of hands-on experience in PCB design, power electronics, and embedded hardware development. I typically work on multi-layer boards, IoT devices, ESP32/ARM-based systems, and production-ready hardware, complementing firmware-focused workflows like yours. Given your strong RTOS and IoT experience, I can add value on the hardware side—schematics, layout optimization, power design, manufacturability, and debugging—helping bridge hardware and firmware for robust final products. If you're open to collaboration or need support on a project, feel free to send me a message. Best regards, Samuel Tshibangu

Hi, We’ve been working across ESP32, ARM Cortex-M, FreeRTOS, and full IoT stacks for quite some time now — including PCB + firmware + cloud-connected systems. We’re comfortable handling complete development, not just coding but making sure the system is reliable, optimized, and production-ready. That’s where most projects actually need experience, and that’s where we fit well. We’ve built similar systems with MQTT, BLE/WiFi, and RTOS-based architectures, so this feels like a natural match for us. One quick question — do you already have a defined architecture, or are you expecting help in structuring the full system as well?

You don’t need another generic embedded developer, you need firmware that is stable, efficient, and production-ready across hardware. I’ll handle your IoT firmware end-to-end, from RTOS architecture to communication layers using ESP-IDF or ARM toolchains, ensuring clean multitasking, low power consumption, and reliable MQTT or HTTP connectivity. My approach focuses on hardware-aware firmware design, meaning fewer bugs, faster debugging, and systems that actually perform in real-world conditions, not just in theory. Do you want this built for rapid deployment or long-term scalability from day one?
