Six surface types

Every surface your business touches customers on.

We build across the full stack of user-facing surfaces — from the marketing site a prospect finds first to the admin dashboard your ops team lives in every day.

Marketing sites

Business websites that load fast, rank well and convert. CMS-driven where it helps, hand-coded where it matters.

Admin dashboards

Internal tools staff actually like using. Role-aware, fast, with the keyboard shortcuts power users need.

Default stack

Boring, proven tech. Custom where it earns its keep.

We use the same stack across projects so we know its failure modes. Custom layers sit on top — not underneath.

FAQ

Questions, answered.

If something isn’t covered here, write to hello@corefluxsolutions.com — you’ll get a real answer within a working day.

Do you do design or just development?
Both. Design and engineering ship from the same small team — no agency-to-dev-shop handoff. You get consistent craft all the way from wireframe to deployed component.
We have a brand already — can you work with it?
Yes. Bring us a brand guide (or just a logo and a colour) and we build the design system out from there. No insistence on starting from zero.
What CMS do you recommend?
Sanity for structured content and complex schemas; Contentful if you’re already in that ecosystem; Payload if you want a self-hosted option that grows into an app backend. We’ll recommend based on your team’s workflow, not ours.
How long to launch?
A marketing site with CMS ships in 3–5 weeks. A full booking platform or client portal is typically 6–10 weeks to a first production release. Mobile apps are 8–14 weeks depending on native complexity.
Can you take over something someone else built?
Yes — with an assessment first. We’ll read the code, flag what works and what doesn’t, and give you a realistic scope for what continuity looks like. We won’t just take the retainer; the code has to be in a state we can stand behind.
Hosting, domain, email — do you handle all that?
We can set it all up in your name and hand it over, or drop into an existing setup. Either way, every credential, account and domain registration ends up owned by you.
