Project details
I have extensive experience (more than 9 years) in developing and creating unique freely programmable controllers based on various architectures - Raspberry Pi, ESP8266, ESP32, STM32, Arduino, and Adafruit Feather for controlling microclimate, heating, ventilation, air conditioning, lighting, etc.
I have designed, manufactured and installed dozens of automation systems that have been operating for many years in various buildings - apartments, high-rise buildings, offices, factories, hospitals and churches.
I develop individual circuits and controller hardware (PCB) depending on the requirements of the customer.
I not only develop the hardware of the controller but also program it, including the logic of operation and the creation of a WEB interface.
For programming, I use free and open-source software, such as C+, Python, JavaScript, HTML, and CSS.

Reverse engineer and recreate high sensitivity photosensor PCB
Dmytro did an excellent job as both a PCB designer and software developer on our project.
They delivered a clean, well-designed PCB layout with proper high-speed and power considerations, along with reliable embedded firmware. The hardware worked correctly on the first revision. Their code was well-structured, documented, and integrated smoothly with the hardware.
Communication was clear and responsive throughout. They met all deadlines and incorporated feedback efficiently.
Overall, a highly competent and professional freelancer. I would hire them again without hesitation.

Job Success
Kyiv, Ukraine - 10:26 pm local time
I design HVAC systems and the controls that make them reliable in real buildings: residential, warehouses, offices, and commercial facilities. With 23+ years in HVAC engineering and 12+ years in cost-effective embedded controllers (ESP32, Arduino, Raspberry Pi), I cover both the mechanical design and the automation layer — so the system works as intended after installation, not only on paper.
What I typically deliver
• HVAC design in Autodesk AutoCAD MEP (heating, cooling, ventilation)
• Building controls / BMS logic for HVAC, boiler rooms, and heat pumps
• Custom controllers and PCB prototyping when off-the-shelf hardware is a poor fit
• Energy modeling with OpenStudio + EnergyPlus for loads and efficiency decisions
• Legacy TAC Xenta / Schneider Electric Xenta and TAC Vista application work (16+ years)
How I work
Designs I create are often assembled and maintained under my supervision, so decisions account for installability, service, and long-term reliability — not just drawings.
Recent related work on Upwork includes greenhouse ventilation calculations, energy simulation for a resort dome project, and embedded/PCB control work for sensors and flow systems.
If you share building type, climate/location, and whether you need design, controls, energy model, or all three — I’ll reply with a clear scope and approach.
Steps for completing your project
After purchasing the project, send requirements so Dmytro can start the project.
Delivery time starts when Dmytro receives requirements from you.
Dmytro works on your project following the steps below.
Revisions may occur after the delivery date.
Technical task
We draw up a detailed technical task in which all requirements for the product will be determined.
Wiring diagram
I draw up the circuit diagram of the system and list the main electronic components.
