For engineering teams managing deployed embedded devices, firmware updates often require expensive on-site technician visits. I provide a complete solution: a production-ready, secure remote update system for STM32 and Arduino based products.
The core deliverable is a client-server application with enterprise-grade security. All communication uses SSL/TLS encryption. User authentication employs bcrypt hashing. The system enforces rate limiting of one hundred requests per minute and suspends accounts after multiple failed login attempts. Every operation is recorded in a detailed audit log with timestamps, user identities, and IP addresses for full compliance. Firmware integrity is verified using CRC32 checksums, supporting files up to ten megabytes.
What sets me apart is my dual expertise in software and hardware. With eight years of experience diagnosing complex PCBs and power electronics, I understand the physical constraints affecting microcontrollers. I write efficient firmware in C and C++ using STM32CubeIDE and Arduino IDE. I use Proteus for circuit simulation and provide PCB layout design. I conduct rigorous real-world testing. I successfully designed a five-point-five-kilowatt Solar Inverter, validated under continuous full-load conditions for over thirty minutes.
Beyond prototypes, I have managed a complete commercial product lifecycle. I architected a specialized electronic control board that successfully reached mass production, with one hundred units currently deployed in the field.
When you engage my services, you receive the complete firmware source code, the configured remote server software, a user-friendly Tkinter GUI application, and full documentation for seamless deployment.
Initiate a conversation through the Guru platform with your STM32 or Arduino model and firmware requirements. I will provide a fixed price quote and realistic timeline promptly. Let's build a robust, secure, and commercially viable remote update infrastructure for your embedded products.
