Project Development

From circuit to code,
from idea to product.

I build embedded systems, circuit boards, IoT and software. From sensor to cloud and from idea to working prototype, I design hardware and software together.

Engineer & Educator

What I do

From sensor to cloud and from circuit board to mobile app, I build end-to-end projects with hardware and software designed together. We can work together on prototypes, product development or technical consulting.

Embedded Systems

C/C++ firmware on STM32, Arduino and ESP32, sensor data acquisition, real-time filtering and hardware–software integration.

PCB Design & Prototyping

2-layer PCB design from schematic to Gerber files in Altium, KiCad, Eagle and OrCAD; fast perfboard prototypes.

IoT & Communication

Wireless communication and real-time data flow with MQTT, Firebase and Supabase; end-to-end IoT from device to dashboard.

Mobile & Desktop Software

Android, iOS and desktop apps with Flutter; Python tools, Django backends and REST API integrations.

Data & AI

Signal processing, data analysis with NumPy/Pandas, CNN-based classification and image processing with YOLO.

Prototyping & R&D Support

Analysis of hardware or software issues in your existing project, improvement plans and technical documentation.

Featured projects

End-to-end work, from hardware to AI.

How it works

  1. 1

    Discovery

    We discuss your needs, goals and constraints.

  2. 2

    Quote & plan

    We agree on scope, timeline and budget.

  3. 3

    Design & build

    Schematics, code and UI take shape step by step, with regular updates.

  4. 4

    Test & validate

    We measure in real conditions and fix issues.

  5. 5

    Delivery & support

    Handover with source code, schematics and docs, plus support afterwards.
