Your hardware idea shouldn't stay on paper. ⚡
You may have the concept, requirements, or even a rough schematic.
What comes next?
Turning that idea into working hardware.
I help take electronics projects from concept through schematic, PCB design, embedded firmware, prototyping, testing, and refinement.
Whether you're building an IoT device, ESP32/STM32 product, custom PCB, or an early-stage prototype, the goal is the same:
Build it. Test it. Make it work.
Have a hardware idea you're ready to bring to life?
Let's build it.

NEW CASE STUDY!
🙌 E-Strum: App + Device for Tracking Light Availability at Home
ABOUT THE APP:
Scheduled and unscheduled power outages in Ukraine made it hard for people to plan their day. The client wanted a hardware device paired with a mobile app that detects light presence in a room and builds analytics from it — so people could plan around real outage patterns, not guesswork.
THE CHALLENGE:
- Take E-Strum from concept to a working hardware + software product:
- Ship secure OTA firmware updates (CI/CD, embedded flashing code, secure distribution server).
- Handle high device load without degrading service.
THE PROCESS:
- Ran discovery first - locked requirements before build, since hardware mistakes are far costlier to fix late than software ones.
- Tackled the riskiest unknowns early - OTA firmware and device-connection logic went first, ahead of UI work.
- Split hardware and backend workstreams in parallel, with device registration/events as the shared contract between them.
THE RESULTS
- Rolled out OTA firmware updates to 1,000+ connected devices with zero manual re-flashing required 💯
Kept backend response times under 300ms even as concurrent connected devices scaled past 1,200 🙌
Held device-connection success rate at 97%+ on first attempt under real-world Wi-Fi conditions 🧠
I didn’t create this video by simply asking AI to “make a vide. There was a process behind it.
I started with the idea and story, then broke it down into individual scenes.
From there, I worked on the visual direction, created the characters and references, and made sure the style stayed consistent across the project.
Then came the AI generation creating each shot, refining prompts, and adjusting the visuals until they matched the story.
After that, I animated the scenes, added transitions, worked on the pacing, sound, and finally brought everything together in the edit.
My workflow:
Idea → Storyboard → Visuals → Character Consistency → AI Generation → Animation → Editing → Final Polish
The tools help me move faster, but the workflow is what makes the final result work.
