Embedded device development teams
Full-stack embedded product development: Firmware/Software, PCB design, mechanical/enclosure engineering, and graphical user interfaces (GUI) built with LVGL and TouchGFX. We ship the idea to production with a single team.
We are a team with many years of experience in this field.
Most clients start with one and end up handing us the whole stack — because the handoffs between them are where products usually stall.
Firmware development
Production-ready embedded firmware for MCUs, IoT devices and industrial equipment — written to your spec, reviewed, and maintainable after we hand it over.
Hardware & PCB
Concept to manufacturable board: schematic capture, layout, DFM review and bring-up for consumer, industrial and IoT products.
Embedded GUI
On-device interfaces built with LVGL, TouchGFX, GUIx and custom UI frameworks — screen flows designed alongside the firmware, with smooth rendering at low CPU and low power consumption.
Software development
Android, iOS, Windows and Linux applications built against our own firmware, plus embedded web apps served from the device — provisioning, configuration and IoT cloud integration.
Production support
Automated test software, test jigs and batch flashing scripts, self-test, component verification and sync into your existing production management system.
Skills
From your idea to a product ready for production
Requirement input
Share your idea or requirement for your project. We analyse it and advise.
Scope & quote
Written breakdown of deliverables, risks and milestones with a price against each one.
Development
We build in your repository and share a working demo every week, so you can see the progress at any time — no surprise at the end.
Release
You receive documented source code, test jigs and flashing tools — everything your factory or your next engineer needs to keep the product running without us.

What our clients say
“The software he developed for our product was well-architected and is maintainable after delivery. He consistently hit deadlines and has the technical depth for embedded systems to resolve items on his own based on schematics and testing.”
“He solved the many issues which came up during our development iterations, even though he was not responsible for them. Very efficient, with a result-driven mentality.”
“Completely rewrote our Arduino-based firmware in a very professional way and added a lot of new features. Highly recommended freelancer.”
“He delivered exactly what was promised. He is extremely knowledgeable about USB and I would definitely hire him again for a similar project.”
“Very professional, timely, and extremely talented. Hoping to work with him in the future. Highly recommend.”
“Outstanding work, very knowledgeable and professional. I had a great experience. I highly recommend them for future work.”
“Quick and efficient, and provided a rapid solution with really good follow-up support. Highly recommended.”
“Put real thought into how to address the problem well before winning the contract, and made himself available to support our needs.”
