# Embedded Systems & STM32 Firmware Development

> As a mechatronics engineer I work where hardware meets software. I designed the system architecture and wrote all of the STM32-based firmware — including MAVLink communication — for a KOSGEB-funded autonomous drone charging station on my own, and ran an ESP32 smart-wristband project end to end, from hardware selection to software.

## Problems it solves

- You need firmware that reads sensors and reliably drives motors, relays or actuators.
- Your device has to talk to a drone, a ground station or a PC (MAVLink, RF, serial).
- The prototype works, but it has to become a product that runs reliably in the field.
- Critical functions such as power management and charging (BMS, solar) must be software-controlled.
- You want the embedded device connected end to end with a desktop or web interface.

## What you get

- Embedded firmware in C / C++ for STM32, ESP32 or Arduino
- Sensor, motor and relay drivers, plus the control algorithms they need
- Communication: MAVLink, RF (RFD900x, XBee), serial
- A PC / ground-station monitoring interface where needed
- System architecture document, test records and source code

## How we work

1. **Free discovery call:** I listen to your need, your current system and your goals, and we talk openly about what is technically feasible.
2. **Scope and quote:** A written scope, milestones, an exact price and a timeline. No surprise costs — what is included is clear from the start.
3. **Build and regular demos:** We progress step by step on the hardware; at every milestone I share a working prototype and test results.
4. **Test and handover:** Bench and field testing, then handover with source code and an architecture document.

## Tech stack

## FAQ

### How much does embedded firmware development cost?

The price depends on the scope; there is no fixed price list. The easiest way to start is Discovery & Feasibility: requirements analysis, technical roadmap, rough plan and proposal document. Discovery and feasibility are free. The price and timeline of the project itself depend on its scope and come as a firm quote at the end of that work.

### Which microcontrollers do you work with?

My projects use STM32, ESP32 and Arduino, with firmware written in C / C++. If you use a different platform, we evaluate it in the discovery call.

### Do you also handle hardware selection and design?

My focus is embedded software and system architecture, and I also take on hardware selection and integration (on the smart wristband I handled hardware, design and software on my own). For work that requires a custom board, we define the scope in the call.

### Can you build an embedded system that talks to a drone / UAV?

Yes. In the autonomous drone charging station, the STM32 control board talks to the UAV over RFD900x using MAVLink, reads voltage / current sensors and drives step motors and relays.

### Prototype or product?

Both. We can turn an idea into a working prototype, or mature an existing prototype into a product that runs reliably in the field.

### Do you work remotely, and in which languages?

Yes. I am based in Türkiye (GMT+3) and work remotely with clients worldwide; meetings are held in Turkish or English and scheduled around your time zone.
