Boutique backend consultancy
Aetherisys is a small, senior team that builds data platforms, APIs and cloud infrastructure for companies that need to move now — extra engineering capacity, without the overhead of big consulting.
We embed alongside your engineers, take a greenfield problem from an empty repository to running in production, and hand back something your team can own and extend.
Why teams bring us in
Senior-only team
Every line written or reviewed by experienced engineers.
Embedded, not arm's-length
We work inside your repository and your standup.
Production from day one
Infrastructure-as-code and CI from the first commit.
You own everything
We hand back code your team can read, run and extend.
What we build
Most engagements draw on more than one of these areas: a data platform needs an API, an API needs infrastructure, a model needs a pipeline to feed it. We work across all four so the seams between them are designed, not discovered in production.
Pipelines, warehouses and the plumbing that makes data trustworthy — tested transformations, explicit contracts, and observability so you know the moment something drifts.
Explore →Models and analytics that ship to production — not just notebooks. Reproducible training, serving and drift monitoring so a promising result survives real data.
Explore →Well-designed services your team can extend and operate. Clear contracts, sensible boundaries, and the logs, metrics and docs that make a service genuinely operable.
Explore →Cloud architecture and infrastructure-as-code: reproducible, observable and fully yours. Every environment defined in version control — read it, review it, rebuild it.
Explore →How we work
We dig into the problem and tell you straight whether we are the right fit — what the work involves, and how fast it could be in production.
We join your team and ship working software in short, visible increments. No big-bang reveals, no surprises at the end.
Tests, observability and infrastructure-as-code so what we build survives contact with real data and real users.
You get documented code your team owns and understands — not a standing dependency on us.
Our standard
Shipping fast only counts if what ships keeps working. Every engagement holds to the same engineering bar — the unglamorous parts that decide whether software survives its first month in production.
Got a greenfield project and a deadline? We embed with your team, ship working software, and hand back something you can own and extend.
Tell us what you are trying to build and where it is stuck. We will be honest about whether we are the right fit, what the work would involve, and how quickly it could be in production — before anyone signs anything.
