Engineer · software to silicon

I turn business needs into products that work, from the cloud API down to the hardware.

I’ve written software since 2011 and hold a B.Eng. in Electrical, Electronics and Communications Engineering. I start from the workflow that hurts, then build the service, integration or device around it.

How I work

From a business need to a working product

01

Understand the workflow

I learn where the business loses time or money: a manual check, a missed payout, a field reading that never arrives.

02

Design the right service

I pick the smallest thing that fixes it: an API, an integration, a serverless function or a device.

03

Build across the stack

Cloud services, webhooks, gateways, firmware interfaces and PCBs. I don’t stop at a layer boundary.

04

Run it in production

Deployments, monitoring and uptime, so the fix keeps working after launch.

Range

One engineer across four layers

Most product problems sit between two layers. I can follow a bug from the API down to the board, or a business rule from the spreadsheet into a service.

The need

Clinicians were paid through manual bank transfers after each shift.

What we built

A Branch API integration that pays out on shift approval, plus custom Bubble.io plugins for Stripe subscriptions and clinician payments.

The outcome

Same-day payment straight to clinician wallets or bank accounts.

Field measurements had to reach the platform wirelessly, without mains power, from inside an explosion-proof enclosure.

What we built

A battery-powered Zigbee wireless transmitter, with custom antenna assemblies that integrate with an Ex d enclosure while keeping its flameproof barrier intact.

The outcome

Wireless field data on a battery runtime of 7 years.
