Full-stack Development

Web apps, platforms, storefronts, and internal tools, built end to end by one team. We care about speed, accessibility, and code your team can live with, and we treat security as part of the build rather than a review at the end.

  • Next.js & React
  • Platforms & dashboards
  • E-commerce
  • Integrations
(Why Zettops)

Built to hold up.


  1. 01

    One team, front to back

    Interface, API, database, and deployment are designed together, so nothing gets lost between a design file and a server.


  2. 02

    Fast on real devices

    We test on slow phones and slow connections, not only fast laptops, and set performance budgets the build has to meet.


  3. 03

    Accessible by default

    Semantic markup, keyboard support, visible focus, and readable contrast are part of every component, checked with tools and by hand.


  4. 04

    Secure as you grow

    Input validation, safe defaults, security headers, and dependency checks are built in, so new features do not open new holes.

What we deliver.

(06 parts)

(Process)

How we work.

Four steps, with you in the loop at every one. No black boxes and no surprises at launch.

  1. Discover

    Goals, users, and risks

    We map the goal, the users, the risks, and agree on what success looks like.

  2. Design

    Reviewed early and often

    Direction, prototypes, and a system, reviewed with you early and often.

  3. Build

    Tested at every step

    Production-grade engineering with tests, security checks, and a live preview at every step.

  4. Launch & grow

    Measured and improved

    We ship, measure, and keep improving: performance, content, marketing, new features.

(Full-stack)

Your project

  • The users, screens, and core flows for the first release
  • The stack: your existing one or one we recommend
  • Integrations with the tools you already use
  • Hosting, environments, and who manages them
  • Testing, accessibility, and performance targets

Later releases, content entry, and ongoing feature work are scoped separately. Scope, timeline, and cost are agreed in a written proposal before any work begins.

(Questions)
01Do you only work with Next.js?

No. Next.js and React are what we reach for most, but we work with the stack that fits the project and your team. If you already have a codebase, we usually build on it rather than start again.

02Can you take over a project another team started?

Yes. We begin with a review of the code, setup, and open issues, then tell you plainly what we would keep, fix, or replace. From there we agree a plan, whether that is finishing the current release or a gradual cleanup.

03What happens after launch?

We hand over the code, access, and documentation, and you choose what comes next. Some clients keep us on for updates, monitoring, and new features; others run it in-house. Either way, nothing depends on us to keep working.
