Embedded Software and IoT Development: End-to-End Solutions from Hardware to Cloud

I develop every layer of an IoT project in-house, from microcontroller firmware to the web management panel.

Quick answerEmbedded software runs on microcontrollers and single-board computers and controls hardware directly. Hakan Sevimoğlu develops industrial IoT projects with ESP32, STM32 and Raspberry Pi, such as a CNC DNC file transfer device, smart irrigation and sensor telemetry.

Tangible results in industry

Solutions like DNC Box, which eliminates USB stick use on CNC machines, are born from real problems on the shop floor. The device software, network communication and management panel are designed together.

Devices can be updated OTA (over the air), their status monitored from a web panel, and their data transferred to ERP or reporting systems.

What I offer

  • Firmware

    C/C++ and RTOS for ESP32 and STM32.

  • Linux devices

    Raspberry Pi-based network devices.

  • Industrial

    CNC DNC, Modbus and PLC communication.

  • Sensors & telemetry

    Data collection, MQTT and alarms.

  • Remote management

    Monitoring and configuration from a web panel.

  • OTA updates

    Secure software updates for devices in the field.

Frequently asked questions

Which hardware do you work with?

ESP32, STM32, Raspberry Pi and industrial devices; hardware can also be selected based on project needs.

Do you support the path from prototype to mass production?

On the software side, support is provided through prototyping, field testing and production-ready firmware.

Can the devices work without internet?

Yes; they can be designed to run on a local network or fully offline.

Can device data be transferred to software?

Yes; it is sent to web panels, ERP and reporting systems via API or MQTT.
