Taking on new projects
Ironwire Systems designs and builds custom software at every layer, from the interface your customers touch to the firmware your devices run. Twenty-five years of hands-on engineering. If it's technical, it's covered.
01 / Expertise
A landing page or a device driver. A one-day fix or a multi-year platform. Design, data, protocols, proprietary systems and everything in between. If it's technical or software, the expertise is here, and it all runs through one engineer who understands every layer.
Interfaces people understand at a glance, design systems and clickable prototypes.
Fast, accessible websites, web apps, customer portals and dashboards.
Services, databases and APIs built to be observed, operated and trusted for years.
Connecting systems that were never meant to talk, and designing the contracts, message formats and protocols between them.
Pipelines, migrations, reporting and analysis that turn scattered records into answers.
Ledgers, payments, billing and bespoke platforms where every cent and every edge case matters.
Low-level integration with terminals, controllers, sensors and custom devices, right down to the wire protocol.
Size of job
All of it, done properly.
02 / Engagements
Three situations I see again and again, and what changes once they're handled properly.
Orders, payments and the ledger drift apart. Month-end means spreadsheets, manual fixes and nervous finance teams.
An integration layer with idempotent syncs, safe retries and automated reconciliation that flags every break.
Numbers that match, an audit trail for every movement, and month-end that takes hours instead of days.
Devices in the field speak their own protocols, drop off the network and fail in ways the vendor never documented.
Drivers and services that talk to the hardware reliably, buffer through outages and surface clean data upstream.
Devices you can monitor and manage from one place, and software that keeps working when the network doesn't.
A critical platform built years ago, poorly documented, fragile to change, with the original developers long gone.
A clear map of how it works, tests around the risky parts, then incremental modernisation behind stable interfaces.
A system you can change with confidence again, and a path forward that never stops the business.
03 / Approach
Money and machines are unforgiving. I design for the failure cases first: duplicates, timeouts, partial writes and out-of-order events.
Logging, metrics and alerts are part of the build, so problems are found by dashboards rather than customers.
I choose tools for longevity and your team's ability to maintain them, not for novelty.
Source code, documentation, infrastructure and IP are yours from day one. No lock-in, no black boxes.
A focused conversation about the problem, the systems involved and what success looks like.
One callA clear scope, technical approach and estimate, fixed-price or time-and-materials.
Written · itemisedIterative delivery with working releases you can see, test and give feedback on.
Regular demosHandover, documentation, and ongoing support or a retainer as you need it.
On your termsThis site is built the way I build client systems: hand-written, measured and locked down. No page builder, no tracking scripts, nothing you don't need.
Taking on new projects
Big or small, front end or firmware. Tell me what you're working with and where it hurts, and you'll get a straight answer on how I'd solve it.
