INDEPENDENT BUILDER. COLLABORATIVE BY NATURE.

Good software.
Better ways
to build it.

I’m Jon. I build open-source tools, lead the technical work at Headway, and help teams find their flow.

THE CRAFT / SELECTED OPEN SOURCE

Small tools.
A better everyday.

Mostly Linux. Sometimes everywhere.
Always an itch worth scratching.

A little more precision. A lot less guessing.

Measure what’s on screen with snapping guides, pinned dimensions, and capture handoff.

THE NEXT CHAPTER / BUILDING TOGETHER

Find your team’s
development flow.

All those little improvements add up. Now we’re bringing that same care to the way whole teams build software.

Fulcrum connects estimates, pitches, shared skills, and project context in one workspace for teams building with AI agents.

Make a plan you can stand behind.

Scope the work, build an estimate, and turn it into a clear proposal. Give clients—and the internal teams you need buy-in from—a shared picture of what comes next.

MADE FOR

Agencies & in-house product teams

A PLAN THE WHOLE TEAM CAN SEE

A shared way to plan, align, and build.

THE PERSON / STILL WRITING CODE

A developer’s CTO.

I’ve been building with Ruby on Rails since 2005. These days, my work spans web applications, native Rust tools, and the people and processes that make good software possible.

As Partner & CTO at Headway, I help teams find the right technical approach and carry it through to a working product. I care about the details in the code and the clarity around it.

Open source is where I put that care into practice. Build something useful. Share what I learn. Make the next person’s work a little easier.

OFF THE KEYBOARD / ON THE SAME PAGE

Good ideas get better
in good company.

Conferences, meetups, and conversations
about the craft of making software.

SPEAKING & CONVERSATIONS

Let’s give developers
something to take home.

I’m available for conference talks, meetups, and conversations with teams. A few things I’d love to talk about:

  • 01Team workflows for agentic development
  • 02Building useful native tools with Rust
  • 03Rails, maintainability & technical leadership
Invite me to speak
COMMUNITY · OPEN TO EVERYONE

Omarchy, in Green Bay.

I organize our local Omarchy meetup. Come trade ideas, compare setups, and meet the people behind the keyboards. Your laptop is welcome.

THINKING OUT LOUD / WRITING & CONVERSATIONS

Notes from the work.

The Even-Keeled podcast

GOOD WORK STARTS WITH A CONVERSATION.

Have something
worth building?

A product, a team, or a room full of curious developers.
I’d like to hear about it.
