What It Is

sgh-electronics is an independent consulting business founded by Sebastian Gonzalez, an electronics engineer with more than 15 years of experience. It focuses on hardware and software development for embedded systems. Rather than offering standardized SaaS developer tools, the platform provides full-cycle custom development services from concept to mass production, covering low-level firmware writing, hardware PCB design, and legacy system modernization.

Core Dimensions

• Features and Use Cases: Its core business is divided into embedded software and hardware development. On the software side, it covers C/C++ bare-metal and RTOS firmware development, legacy code migration, and CI/CD pipeline setup. On the hardware side, it provides schematic design, PCB layout, and EMC/EMI considerations, while also supporting hardware-software integration and debugging.
• Supported Languages/Frameworks: Software development primarily uses C/C++ and assembly, with support for MCUs such as STM32, PIC, and AVR. Testing frameworks include GoogleTest, Ceedling, and others. Hardware design tools include KiCad, Fusion360, and NI suites.
• Industry Expertise and Integration: The service has deep expertise in medical devices, with familiarity in IEC 62304 and ISO 13485 compliance, as well as industrial automation. It demonstrates strong awareness of regulated development requirements and can deliver deep hardware-software co-integration.

Pricing

The website does not disclose any specific pricing information or billing model. As a custom consulting service provided by a freelancer, it typically likely follows project-based or hourly billing, requiring direct contact via email for discussion.

Pros and Cons

• Pros: The founder has a strong dual background in both software and hardware. 12 years of medical device development experience ensures a high level of reliability and compliance awareness. The service emphasizes code quality, design for manufacturability, and complete engineering documentation.
• Cons: As an independent solo consulting model, capacity is limited, making it difficult to take on large-scale parallel development projects. There is no standardized product, so it cannot be used out of the box. No public pricing reference is available, which increases the upfront communication cost.

Who It’s For

Best suited for external teams that need high-reliability embedded system development, especially startups in medical devices, industrial automation, and audio electronics, or hardware teams lacking embedded expertise that need to outsource an end-to-end solution from low-level firmware to PCB design.

Access in China

Unknown. As a personal consulting website based in Germany, it is typically unlikely to be specifically blocked, but access speed in China may depend on its overseas server deployment.
