Senior-led AI consultancy
We help companies build with AI, train their teams, and advise their leaders.
Senior experience, embedded in your team. We start with one small feature and grow into a long-term partnership.

A Calm Co Three ways we work
Build. Train. Advise. Each ends with something you own.
Engineering and operations, same rigour. We work best with ambitious teams in complex, regulated environments: production AI in the product, and internal tools that finance, legal, marketing and ops teams own and run.
Read how a deployment actually runsBuild.
We bring senior experience and build with your team, in your codebase, in your stack, teaching as we go. Production AI features, and internal tools for finance, legal, marketing and ops that the team owns end-to-end.
How it runs
Senior engineers embedded in your team. Starts with one feature and usually grows into a long-term partnership.
Train.
Not a workshop. A senior engineer, a peer who has already made the switch, a real problem from your backlog, and room to learn by shipping.
How it runs
Small cohorts of three to four engineers, or continuous pairing inside a build engagement.
Advise.
Senior-led advisory beside your leaders. Most engagements open with a five-dimension readiness benchmark: interviews across your teams, ending in a ranked action list.
How it runs
After the benchmark, ongoing advisory beside your leadership for as long as it earns its place.
How an engagement runs
Start small. Grow from there.
Every engagement starts with one small feature and senior engineers embedded in your team. Most grow into long-term partnerships: new features, new teams, new functions.
We begin by shipping.
We arrive with a thesis and put real work in front of internal users early. No discovery theatre, no kickoff deck.
A steady release cadence.
Pair programming, code reviews, architecture counsel. Usually a few threads at once: a retrieval pipeline, a model call path, a piece of internal tooling.
Honest checkpoints.
What is in production, at what cost, at what quality. We almost always restructure something here, and name who owns each piece going forward.
Them-and-us becomes them.
The team pushes back on our design choices and is right. Someone ships a feature we did not propose. That is progress worth celebrating.
Everything written down.
Runbooks your team can follow, quality checks that keep learning from real usage, and every architecture decision on record with the option we rejected.
Marie Founder, A Calm Co
A note from a client
“Chris is a very experienced senior engineer who quickly grasped what our product needed, even with incomplete input and without handholding.
He worked closely with our CPO on v2 of our product, while our CTO trusted him fully and could focus on other parts of our engine. Chris works fast, reliably finds solutions, and treats everyone with genuine respect. We’d gladly work with him again!”
From the field
Notes from the work.
Patterns we see often enough to write down. No hype, no predictions. Full essays in the articles index.
On changing how teams work
A lot of teams added an agent and kept working the same way, so the gains were small.
On scoring readiness
The score is a side effect. The action list is the deliverable.
On exhausted teams
The mandate from above is real. The exhaustion below is real. Both are pointing at the same fact.
On week one
There is no discovery phase. There is no kickoff deck. Week one is shipping week.
The other half
goldenberry.studio We build a lot, too. Meet the Studio.
Consulting is one side of Goldenberry. The other is an independent software studio shipping products thousands of people use. Much of what we bring to clients was first tested on something of our own.

Build with AI. Start with one feature.
Thirty minutes, free, and a working session rather than a pitch: we look at your situation and pick where AI would pay off first. You leave with a ranked next move whether or not we work together. If it fits, we start with that one feature and grow from there.
