Design and engineering in one team

Most web and app projects break at the handover: a design nobody costed, a build that quietly drops half the interaction, an agency that goes quiet at launch. We keep design, engineering and release under one roof, so what gets drawn is what gets shipped, and what ships is something your team can keep changing without calling us first.

Designed for the decision

Every screen is built around the action it should produce, so layout, copy and pacing serve the conversion rather than the portfolio.

Fast on real devices

Performance budgets are set at kickoff and checked on mid-range phones and ordinary connections, not on the machine that built it.

Built to be extended

A shared component library, typed code and clean data models mean the next feature is an addition rather than a rewrite.

Accessible and search-ready

Semantic markup, keyboard paths, metadata and structured data are part of the build, so the site is usable and indexable on day one.

One system behind every screen size

We build from a single component system, so a change to a button, a form or a card lands everywhere at once. Your team gets a product that stays consistent as it grows, and a CMS that lets marketing publish without a developer in the loop.

Web and app services for teams that ship

End-to-end products and the systems around them, designed to load fast, convert the traffic you pay for and keep scaling long after launch.

Marketing websites

Fast, well structured sites with a CMS your marketing team can run without help. Built for the traffic you are already paying for, with analytics and conversion tracking wired in before launch rather than after it.

Web applications

Dashboards, portals and internal tools with real authentication, roles and data behind them. Engineered as products rather than pages, so state, permissions and the awkward edge cases are handled properly.

Mobile apps

iOS and Android builds from one codebase where that serves you, and native where it does not. Offline behaviour, push, deep links and store submission are part of the scope, not a surprise at the end.

E-commerce builds

Storefronts engineered around the checkout: fast catalogue pages, a payment flow that does not lose people, and the product, inventory and fulfilment integrations that keep the back office in step.

UI and UX design

Research, flows, wireframes and a design system your brand can grow into. Prototyped and tested with real users before engineering starts, so the expensive decisions are made on evidence.

Hosting, support and care

Deployment pipelines, monitoring, backups and a maintenance plan with named response times, so someone is watching the thing you just launched.

Considered design, engineered properly

Design systems

We design in components, not pages, so type scale, spacing and states still hold together after twenty people have touched the site.

Front-end engineering

Server rendered where speed and search matter, interactive where the product needs it, and measured against a performance budget on every release.

Product and platform builds

Authentication, roles, billing and admin tooling decide whether a product survives real users, so we build them once, properly.

Content and commerce

A CMS modelled on how your team publishes, or a storefront modelled on how you sell, with structured fields and live preview.

Mobile applications

Native where the hardware matters, cross-platform where it does not, shipped to the stores with crash reporting and analytics already wired in.

Scope it, design it, ship it with Prob N Tech

Discovery and scope

We agree what the site or app has to achieve, what belongs in the first release and what can wait, then price against that rather than against a wish list.

Design and prototype

Flows first, then a clickable prototype of the screens that carry the most weight, reviewed with you before a single component gets built.

Build and test

Two week increments with something you can click at the end of each, tested across the browsers, devices and breakpoints your analytics say your users are on.

Launch and iterate

Staged release, monitoring, and analytics read against the goals we set at kickoff, then a backlog we work through together instead of a final invoice and silence.

Prob N Tech + a stack chosen for the job

Picked for what the project needs, not for what is trending.

Frameworks, hosting and content tooling are selected on what your team will have to maintain after we hand it over. The architecture stays conventional where being clever would cost you later, so hiring for it is never a problem.

Northlane replaced three disconnected sites with one platform

"We were running a marketing site, a customer portal and a careers page that agreed on nothing. Prob N Tech rebuilt all three on one design system and one codebase, and the difference showed up in the numbers within a month. Our team publishes campaign pages now without opening a ticket."
