About this gig
Are you looking for reliable Arduino or ESP32 firmware
that actually works?
I develop embedded C++ firmware for IoT projects
from simple sensor readers to full WiFi systems with
MQTT and web dashboards.
What I can build for you:
- Sensor reading (temperature, distance, humidity, PIR)
- Relay and motor control automation
- LCD / OLED display integration
- WiFi connectivity and MQTT data publishing
- Web dashboard for remote monitoring and control
- Obstacle avoidance and autonomous systems
How I work:
Simulate everything in Wokwi before delivery
Clean, well-commented C++ code
Full documentation included
Fast communication I respond within hours
My latest project: full IoT liquid dosing system with
ESP32, real-time MQTT, and web dashboard.

Hey! I'm Valentin, an Embedded Systems Engineer
from Romania with a degree in Automation &
Computer Science.
I love the moment when code meets hardware and
something actually works. My diploma project was
an autonomous robot — and I've been hooked ever
since.
I build Arduino & ESP32 firmware in C++, tested
and documented before delivery. Latest project:
full IoT system with MQTT and web dashboard.

FAQ
What types of Arduino/ESP32 projects can you help with?
I can help with sensor integration, relay control, LCD displays, WiFi connectivity, MQTT systems, and IoT automation. If you're unsure, just message me!
Do you need physical hardware to complete my project?
No! I simulate and test all projects in Wokwi simulator before delivery, so no physical hardware is needed.
What do I receive when the project is done?
You receive clean, well-commented C++ source code, wiring diagram, and full documentation. Everything is tested before delivery.
Can you fix existing Arduino code that doesn't work?
Yes! Bug fixing is one of my specialties. Share your code and describe the problem and I'll get it working.
