A boutique backend software consultancy.
Aetherisys is a small team of senior backend engineers. We work with mid-sized companies — real revenue, lean dev teams, not much red tape — who need to build new things quickly and well.
Most of our work is greenfield: data platforms, APIs and microservices, cloud and infrastructure-as-code. We embed alongside your team as extra capacity, ship working software, and leave you with something you can own and extend.
Traditional consultancies solve their staffing problem by putting bodies on your project. We solve yours by putting a small number of genuinely senior people on it — engineers who have built and operated these systems before, and who would rather ship a focused thing well than bill a large thing slowly. There is no bench to feed, so there is no incentive to stretch the work.
We stay on the bleeding edge of AI-assisted development — and we pair it with experienced engineers who review every line. You get the speed of modern tooling with the precision and judgement of senior people. Fast does not mean careless.
In practice that means short feedback loops and working software early. We would rather show you something running at the end of the first week than a deck at the end of the first month. We work in your repository, against your standards, in the open — so the project never depends on a handover document to make sense.
No slideshows, no bench-warming juniors, no theatre. Just a focused team doing high-impact work and getting it shipped.
The point of an engagement is the state your team is in when it ends. We aim to leave you with software that is tested, documented and observable — infrastructure defined in version control, services your engineers can read and extend, and no dependency on us to keep the lights on.
We are happy to stay involved where it genuinely helps, but a good outcome is one where you do not need us to. If you want to know how we would approach a specific problem, get in touch — we will tell you straight.
