01 / What we can make happen

Where do you want
to go from here?

You bring the business problem.
I bring the curiosity, craft, and code.

01

Build something new.

Turn an idea into software people can use, from the first sketch through production.

From idea to launch
02

Make it work better.

Find the cause of slow, fragile software. Improve it with changes you can measure.

From fragile to dependable
03

Bring it all together.

Connect your tools and data so work moves between systems without the manual steps.

From manual to automatic
Explore all services

02 / Less talk. Working software.

The proof is
in the progress.

Real projects. Specific outcomes.
And the details behind every number.

Logistics / Data engineering

A whole lot less waiting.
A whole lot more doing.

A dispatch and billing pipeline took 11–16 minutes to refresh. I built the data platform and worked through the bottlenecks, bringing the cycle below 20 seconds on the same server.

04 / A person. Not a handoff.

Hello, I’m Austin.
Your idea’s next
co-conspirator.

I’ve been shipping software since 2003. Aternex is my independent software practice: a place for ambitious ideas, stubborn problems, and the satisfaction of making things work well.

When you hire Aternex, you work directly with me, from the first conversation to the code in production. I get to know your business, explain the tradeoffs, and stay close to the details.

Meet the person behind the code

A clear path from here to there

Good work starts
with a good conversation.
