What we do

Custom software and applied AI, engineered end to end.

Not a menu of agency services — one engineering practice that takes a system from architecture to production, and stays to operate it.

01

Custom Software Engineering

Systems built to your domain, not bent around a template.

  • Custom development
  • Web applications
  • Mobile applications
  • SaaS platforms
  • Backend systems

02

Applied AI

AI treated as production engineering, not a demo.

  • Grounded AI (retrieval + evals)
  • Agents & automation
  • ML systems
  • Guardrails & observability

03

Scale & Systems

Foundations that hold from the first user to the millionth.

  • Scalable architecture
  • System integration
  • Modernization / migration
  • Operate & optimize

How you work with us

Four ways to bring us in.

Pick the shape that fits where you are — each one is senior engineers owning a hard part end to end.

New build

A product or system from architecture to production. You get working software and a team that stays to operate it.

Modernization / migration

Move off a legacy core without stopping the business — incrementally, measured at each step.

Embedded engineering team

Senior engineers who plug into your team and own a hard part of the system end to end.

Architecture review

A fixed-scope read of your system’s design, load path, and risks — with a plan you can act on.

START SMALL

Not ready for a build? Start with the architecture.

The smallest sensible way to work with us. Fixed scope, fixed price, and the document is yours whether or not anything follows it.

Book an architecture review
  1. 01A written read of the systemDesign, data model, load path, integration points, and the failure modes nobody has written down yet.
  2. 02Risks ranked by what breaks firstOrdered by what will actually bite you under real traffic — not a severity matrix that flags everything.
  3. 03A plan you can act on without usWhat to change, in what order, and what each change buys you. Costed in effort, not in adjectives.
  4. 04A call to walk through itWe go through the document with your team and answer the follow-ups. No slides.

If the honest answer is that your system is fine and does not need us, that is what the document will say.

How we work

A process built for real systems.

Four stages, each ending in something you can inspect.

STRAIGHT ANSWERS

The questions that decide it.

What technical buyers ask before the first call. Short answers, no qualifiers.

Do you work fixed-price or time and materials?
Both, chosen by how well the scope is known. Architecture reviews and discovery are fixed-scope and fixed-price. Builds run on a monthly rate against a written plan, because a fixed price on a system nobody has architected yet is priced fiction — you pay for the padding. If scope changes materially, we re-quote in writing and you decide whether to add it, defer it, or cut something to make room.
Can you take over an existing codebase?
Yes, and often. It starts as an architecture review: a written read of the design, data model, load path, tests, infrastructure, and the risks worth acting on. You keep that document whether or not the engagement continues. We will tell you if the honest answer is that the system is fine and does not need us.
Who actually writes the code?
Senior engineers, with the founder accountable end to end. No junior pyramid, no account manager between you and the people building the system. Specialists join for their phase — that is what keeps the team senior instead of large.
Who owns the code and the IP?
You do, in full, on payment — source, infrastructure definitions, documentation, and the accounts they run in. Nothing is held hostage in a proprietary wrapper or a platform only we can operate. Building to hand over is a design constraint from the first commit.
What happens after launch?
Launch day is where the system starts earning its keep, not where the work stops. Either we operate it with you — running it under real traffic, tuning cost and performance on measurements, extending it — or we hand it over with documentation and runbooks written for the team that takes it. Both are normal; neither is a lock-in.
How fast can you start, and what is the smallest engagement?
An architecture review is the smallest sensible piece of work and can usually start within a couple of weeks. A full build starts when discovery is done and we have capacity to deliver it properly — we would rather tell you to wait than take a build we cannot do well.

Something not answered here? Ask it directly — a senior engineer reads every inquiry.
