SI30 — Systems Integration Brisbane, AU

SI30.

Hardware to app to cloud. One engineer, no handoffs.

Firmware, boards, iOS and the cloud behind them. Built by the same person, so there is nothing to integrate at the end.

The problem

Device projects don't fail at the bench. They fail at the seams.

The usual setup is three teams and one integration phase bolted on the end. Hardware slips, so firmware stalls. Firmware changes an interface, so the app starts over. The schedule dies in integration, and it dies because there were three teams.

No integration phase

I hold all five layers, so there is no handoff to lose things in. Software agencies cannot answer this, because they cannot lay out a board, write firmware, or deal with RF.

Who this is for

You have a device and no straight line from the sensor to the screen.

A prototype that works on the bench but won't survive a customer. A board with no app. An app with no cloud behind it. A firmware engineer who left. Sensor data you can't defend to an investor.

What I do

Four things. Fixed price, scoped before we start.

A

Bring-Up Review

$3,5001 week

I read the whole chain and hand back a costed path to something shippable, with the integration risks named and ranked. Start here.

B

Sensor Data Forensics

$6,5002 weeks

Your device produces numbers you don't trust and nobody can tell you why. I measure it, isolate the actual cause, and hand back the fix with the evidence behind it.

Almost nobody sells this

C

The Missing Layer

$14,0004–6 weeks

You have two of the three and need the third. Firmware for your board, an iOS app for your device, or the cloud and OTA sitting behind both.

D

Device to Cloud

from $30,000by quote

The whole chain. Firmware, transport, app, backend, fleet management and over-the-air updates. One of these at a time.

Proof

Built, shipped, and in someone's hands.

ProxAI assistive glasses

Dual ESP32 nodes, 8×8 time-of-flight depth, IMU sensor fusion, bone-conduction audio, BLE for configuration and a UART-to-UDP path for realtime. iOS app, over-the-air firmware, custom PCBs to fab-ready gerbers. In the field with a real user. International patent application filed, Australian regulatory pathway underway.

A sensor error nobody could explain

Traced to magnetic interference from the device's own speakers, by measurement rather than guesswork. Orientation error correlated at r = 0.955 against net rotation, while the geometry itself cleared at 1.73 mm against 1.2 mm of sensor noise. That is the difference between knowing and hoping.

The software half

A regulated multi-platform care platform. 168,000 lines, a worker app and an office app over one database, 138 row-level security policies, 1,908 tests. Built in five days.

How I work

Fixed priceAgreed before I start. You get the deliverable, not my timesheet.
You own itCode, firmware and board files are yours.
Two at a timeWhich is exactly why A comes first.
RemoteOn site when the hardware needs hands on it.

Get in touch

Tell me what the device is and where it's stuck.

Two paragraphs is plenty. You'll get a straight answer within one business day: which of the four fits, or that none of them do and who to ask instead.
