/ Services
Where we go deep,
and where we can help.
Three signature services define what we're known for. Four core services cover the standard build work. One specialty add-on lives at the bottom — it exists, it's real, it just isn't the point.

/ Why RHS Design
A studio that treats production as the deliverable.
A lot of shops will hand you a demo that works on the happy path. We ship things that survive real users, real data, and a real on-call rotation.
- 01
We fix what AI breaks
Half our inbound is founders whose AI-built product started falling over. We know that codebase — the same anti-patterns, the same missing validation, the same SQL injection every time.
- 02
Senior only, always
You talk to the person building your product. No account manager, no offshore handoff. Small team by design.
- 03
Transparent by default
Fixed scopes with clear deliverables. Async updates you can actually read. Access to the repo from day one.
