Delivering reliable firmware, IoT platforms, and industrial automation systems.
Gestell is an engineering-first company delivering production-grade embedded systems, scalable IoT solutions, and industrial controllers for real-world applications.
With 7+ years of hands-on industry experience, we design systems that prioritize reliability, clarity, and long-term maintainability—from firmware and RTOS layers to device connectivity and engineering tools.
How we work
- Architecture before implementation
- Small, testable, and extensible components
- Clean interfaces, strong documentation, and predictable delivery
| Vision | Mission |
|---|---|
| Enable smarter industries through clear, reliable embedded engineering. | • Deliver optimized, production-ready firmware • Build scalable IoT & industrial systems • Accelerate clients’ product development • Establish long-term engineering partnerships |
- MCUs: STM32, ESP32, ESP8266, AVR, NXP
- Execution: Bare-metal, RTOS (FreeRTOS)
- Drivers: HAL/LL, peripheral & board support
- Comms: UART, SPI, I2C, CAN, RS485
- Protocols: MQTT, HTTP, WebSocket
- Cloud: HiveMQ, AWS IoT, custom brokers
- Integration: Mobile apps & dashboards (Flutter)
- Standards: Modbus RTU / TCP
- Systems: Industrial controllers & RTOS-based control
- Focus: Reliability, safety considerations, deterministic behavior
- Desktop: Qt-based configuration & debugging tools
- Mobile: Flutter applications
- Use cases: Device setup, monitoring, diagnostics
| Category | Stack |
|---|---|
| Microcontrollers | STM32, ESP32, ESP8266, AVR, NXP |
| Operating Systems | Bare-metal, FreeRTOS, Embedded Linux |
| Protocols | MQTT, Modbus, CAN, RS485, BLE, Wi-Fi |
| Tooling | CubeMX, PlatformIO, Keil, VS Code |

Our workflow is optimized for predictable delivery and production readiness:
- Requirement Analysis — Functional & technical alignment
- System Architecture — HW/FW/Connectivity design
- Implementation — Modular, documented C/C++ firmware
- Testing — Unit, integration, and stress testing
- Delivery — Source code, firmware, and documentation
- Support — Optional maintenance & long-term collaboration
- ✅ 7+ years of real-world embedded engineering
- ✅ Architecture-driven development (not quick hacks)
- ✅ End-to-end delivery: firmware, tools, and integration
- ✅ RTOS & industrial protocol expertise
- ✅ Clear communication and fast turnaround
| Model | Best For | Typical Range |
|---|---|---|
| Fixed Price | Defined modules, firmware, tools | $200 – $2,000 |
| Monthly Retainer | Ongoing development & support | $500 – $1,500 / mo |
| Hourly | Flexible tasks & consulting | $15 – $30 / hr |
Pricing varies based on scope, complexity, and technology stack.
