Our Process

From Napkin Sketch
to Deployed Device

01
Discovery

Requirements gathering, use-case mapping, and feasibility study.

02
Architecture

System block diagrams, component selection, and cost modelling.

03
Prototyping

Breadboard → PCB → enclosure. Iterative hardware builds.

04
Firmware

Embedded software, OTA pipeline, and integration testing.

05
Production

Pilot run, QA testing, and full manufacturing handoff.
