— Why TNXN

Why engineering teams choose us

Engineers, not assemblers

We don't string together no-code tools. Our team writes production TypeScript, ships well-tested code, and reviews PRs.

Performance obsessed

App Router, RSC, edge rendering, image optimisation. Lighthouse 99s aren't an accident — they're the default.

Type-safe end to end

TypeScript everywhere. tRPC or generated SDKs across the stack. Fewer runtime bugs, faster feature delivery.

Design systems, built right

Tailwind + a shared component library. Consistent UI, faster iteration, no design drift as your app grows.

Ship in weeks, not quarters

SaaS MVPs in 8–12 weeks. Marketing sites in 3–4. We work in tight, demo-able sprints with you involved every week.

Hand-off or stay on

Clean repo, full docs, CI/CD configured. Take it in-house, or keep us on a retainer — your call.
