Siere Soft is three engineers who'd rather ship working software than charge for the meeting where we agree to ship working software.
We've been shipping production systems for fifteen-plus years each — backends, mobile, infra, the lot. When LLMs landed, we built with them every day instead of writing think-pieces about them.
Our work now sits between the two things that used to be separate jobs: senior product engineering, and the new craft of designing systems that work alongside language models. We think the line between those will be invisible by 2030; we're already used to working on the side of the line where it doesn't matter.
If we're a fit, you'll know inside one call. If we're not, you'll know inside one call too — and we'll tell you who you should be talking to instead.
Fifteen years in product engineering, the last four heavily on AI-native systems. Founded Siere AOE in 2024 after watching three different brand teams realise their websites were getting more LLM traffic than human. Writes the specs you read on this site.
Twelve years in mobile and systems engineering — Kotlin, JVM backends, the kind of resilient infra work that doesn't make demos but does make payroll. Joining Siere Soft as co-engineer; introduction here when contracts and gardening leave permit.
No juniors hidden behind the masthead. No 60-page proposals. We write a spec, agree it, then build the thing — and we'll tell you straight when we're not the right shop for it.
Everyone who'd touch your work has shipped production systems for the better part of a decade. We don't sub out to juniors and we don't grow until we can keep that line.
Outcomes, scope, risks, and what's noton the table — written down, on a page, before week one. It's how we both find out if we agree.
We use AI assistants on every engagement — our own harness, in fact. It's why a team of three can do the work of a team of eight, without the corresponding bill.
If your problem is mostly frontend, or mostly enterprise change management, or mostly slide deck — we'll send you somewhere better. Quickly.
