Consulting & Development

Engineering Services

From bare-metal firmware to full IoT device pipelines — EFH delivers the depth you need without the overhead of building an in-house team.

What We Offer

Firmware engineering,
end to end.

Each engagement begins with a clear architecture discussion and ends with documented, maintainable code.

Why EFH

How we work.

📐
Architecture First
Every engagement starts with a documented architecture — no code before the design is agreed.
🧪
Testable Deliverables
Code ships with unit tests, hardware test scripts, and a bring-up checklist — not just source files.
📄
Documented Interfaces
Every module has a documented API, state machine, and register-level implementation notes.
🔄
Iterative Collaboration
Regular check-ins, working branches, and review sessions keep your team aligned throughout.

03
Iterative Development
Milestone-based development with working firmware deliverables, test reports, and regular sync calls.
