Product engineering
From a Figma file or a back-of-napkin sketch to a production app your customers depend on. Weekly demos, not quarterly reveals.

Software, shipped with intent.
Zenosolution is a small product engineering studio. We embed with founders and product teams to design, build, and ship the kind of software that compounds — calm to operate, fast to extend, and a pleasure to use.
Four ways we plug in.
We work in tight, senior pods — usually two to four engineers and a designer. No layers between you and the people writing the code.
AI product work
RAG pipelines, agentic workflows, internal copilots. We focus on the boring 90% — evals, guardrails, latency — so the magical 10% actually ships.
- LLM features in existing apps
- Evals, tracing, observability
- On-call for production agents
Platform & infra
Quiet, durable backends. Migrations that don't keep you up at night. CI that gets out of the way.
- Postgres & event-driven systems
- Cloud architecture (AWS, GCP)
- DX, CI/CD, observability
Design engineering
Where the design system meets the components. Accessible, fast, and consistent across every surface.
- Design system implementation
- Marketing sites & landing pages
- Motion & interaction polish
A predictable rhythm, from kickoff to launch.
No surprises, no agency theatre. Just a steady cadence of shipped work and clear weekly signal.
-
01
Discovery week
A focused, paid one-week sprint. We pressure-test the problem, scope, and stack — and write the brief together. You walk out with a plan, even if we don't build it.
-
02
Build sprints
Two-week sprints, demoed every Friday. You see the work running on real infra from week one, not week ten.
-
03
Launch & harden
We don't disappear at launch. Telemetry, on-call runbooks, and a 30-day stabilization window are part of every engagement.
-
04
Handover or stay
Some teams hire what we built. Others keep us on retainer for the next chapter. Either path is the right one.

B2B SaaS · v2 rewrite
Northwind — a calm replatform, no downtime
Moved a six-year-old Rails monolith to a typed, event-driven stack — one slice at a time, with zero customer-visible downtime.
Boring tech, sharply applied.
We default to tools we trust at 3am. We'll happily learn yours — but we won't push novelty for novelty's sake.

Zenosolution shipped more in eight weeks than our previous vendor did in nine months. They write the code, but more importantly they sweat the things we forgot to ask about.
