From a Garage to a Global Practice

CustomDev LLC started in 2004 as a one-person consultancy specialising in microcontroller firmware for industrial clients. Over two decades, we've grown into a multi-disciplinary engineering firm with deep roots in both hardware and software.

Today our team works across embedded systems, PCB design, cloud architecture, and custom application development — all under one roof. Every engineer at CustomDev has shipped real products, not just prototypes.

We're remote-first with clients across North America, Europe, and Asia-Pacific, but we've never lost the scrappy, hands-on spirit that started in that garage.

Our Core Values

🎯
Engineering First
We make decisions based on physics, data, and engineering judgment — not trends or buzzwords.
🤝
Client Ownership
We treat your project like it's ours. We invest in understanding your goals before writing a single line of code.
🔍
Radical Transparency
No surprises on scope, timeline, or budget. We communicate early and often, even when the news is hard.
♻️
Long-Term Thinking
We design for maintainability and longevity. Products we ship in 2026 should still be serviceable a decade from now.
