都市猫 / Design + Engineering Studio
Digital products, designed and built end to end.
Urban Cats is a studio for teams who need the whole stack handled — interface, product, the infrastructure underneath, and the AI running through it. One team, from first sketch to what's live in production.

What we do
Five disciplines,
one team that ships
Most work touches more than one of these. We keep them under one roof so the seams don't show — and nothing gets lost in a handoff.
- Web
Websites & marketing
Sites that load fast, rank well, and look like nobody else built them.
- Design + build
- SEO & performance
- CMS when you need it
- Product
SaaS platforms
Multi-tenant products, dashboards, and the design systems that keep them coherent.
- Design systems
- Dashboards
- Billing & auth
- Apps
Desktop & mobile
Native-feeling apps for iOS, Android, and the desktop from one product vision.
- iOS / Android
- Electron / Tauri
- Offline-first
- Infra
Infrastructure & automation
Pipelines, deploys, and the glue that makes shipping boring — in the best way.
- CI/CD & IaC
- Observability
- Cost & scale
- AI
AI agents & RAG
Retrieval systems and agents wired into your real data and the workflows around it.
- RAG pipelines
- Tool-using agents
- Evals & guardrails
How we work
From brief to in production
- 01
Discover
We map the problem, the users, and the constraints before anyone touches a pixel or a repo.
- 02
Design
Interface and architecture move in parallel, so the thing you see and the thing underneath actually fit.
- 03
Build
Typed, tested, reviewed, shipped in small increments. You see it working long before launch.
- 04
Operate
We stay for the unglamorous part — monitoring, iteration, and scaling it as real usage arrives.
Capability in practice
The shape of what we take on
// Representative engagements — the kinds of problems we're built for.
Realtime operations
An ops dashboard streaming live events at scale.
Tens of thousands of events a second, rendered without dropping frames, on infrastructure that scales down when nobody is watching.

One product, every screen
A single product across web, mobile, and desktop.
A shared core with native shells per platform, so the team ships one feature once and it lands everywhere on the same release train.

The toolkit
Boringly reliable, where it counts
We're not religious about tools — we pick what fits the problem and what you can maintain after we hand it over. This is where we tend to land.
