The workflow spans too many screens
Users lose context while moving between records, forms and approvals.

Turn complex workflows into usable web applications
For product teams building a customer portal, a dashboard or an internal tool people rely on every day. We build React or Angular front ends wired to your APIs and your permission model, including the loading, empty and error states agreed with your designers. React work can start from Wideset, the design system we built with Widelab, our product design brand: AI-native components that coding agents use the way your designers intended. Accessibility comes in from the first screen: for WSB Merito we shipped a bilingual WordPress platform to WCAG 2.1 AA, with documentation ready when the ministerial audit came.

This is for you if you need a browser product people can use
Design and implementation keep diverging
Every new screen invents its own buttons, and AI coding agents add lookalikes faster than anyone can review them. You need shared components that designers, engineers and agents all use.
Accessibility is part of the brief
Sometimes accessibility is written into the contract, with an audit at the end. Keyboard use, focus states, contrast and screen readers have to hold on every screen.
Different roles see different things
A manager sees only their team, an owner sees the whole portfolio. Permissions have to be enforced on the server, not only hidden in the screens.
What you get. An interface connected to the work
Implemented application flows
Screens and interactions for the agreed user journeys, including loading, empty and failure states.
AI-native React components
Wideset, built with Widelab: 50+ components on Radix, Tailwind and CVA, documented in Storybook and covered by tests. An agent guide maps each UI intent to a component, so AI agents reuse parts instead of inventing new ones. Your brand goes in a theme layer.
Workflow and accessibility checks
Core journeys and the agreed WCAG level verified across browsers and devices, with a record of who addressed each requirement and how.
Roles that hold on the server
Role-specific journeys built on the backend's permission model and tested as each role.
Tech stack. Interfaces on a design system
Accessible front ends on React or Angular, with Wideset components on Radix and Tailwind, and headless content where editors need control.

How we work
Build complete journeys, then expand
We choose a useful path through the application and deliver it with its data integration. Reviews cover how the flow behaves when information is missing or a user cannot complete an action, alongside the intended visual design.
Pirxey is a very communicative and caring team.
How it works. From user task to browser release
Understand the task
Map the user journey, content needs and permissions with product stakeholders. Agree the screens and states the first release must cover, including empty results, failed requests and restricted access. Keep later features visible in a separate backlog.
Align interface and data
Check designs against what the API actually returns and agree the reusable components the flow needs, from your design system or from Wideset.
Build and exercise the journey
Implement the interaction and check how it behaves across the agreed browsers, devices and accessibility scope.
Prepare the next increment
Review the working flow with you and prioritize the next area of the application.

Questions about building a web application
- No. We work in your repository, your cloud and the tools your team already uses. If one of them gets in the way of the work, we tell you what and why, and you decide.
- With a 30-minute scoping call. We look at what you have and what you need, then propose a first step with its scope and price before any work starts.
- Yes. We inspect the components and usage rules you already have, and new interface work extends that system where the product requires it. If you don't have one, React projects can start from Wideset, the design system we built with Widelab, with your branding applied through a theme layer. We have also implemented a design system for Redpanda Data: new components, app templates, patterns, Storybook examples and documentation.
- The components ship with a guide written for AI coding agents: a table that maps each UI intent to the right component, a list of anti-patterns, and the typography and token rules. An agent building a screen picks an existing component instead of generating a lookalike, so screens stay consistent as the codebase grows. Wideset is a private package, not open source.
- Yes. Product designers can work in the same team as the engineers when design is part of the engagement.
- Contrast, focus states, keyboard navigation and screen-reader support, checked on every screen in scope. On WSB Merito, WCAG 2.1 AA was a contractual obligation with a ministerial audit at the end; our delivery documentation showed each requirement, who addressed it and how.
- Yes. On the construction platform, contractors, subcontractors and owners share one system, and the owner gets a portfolio view across projects. Interface restrictions are always backed by checks on the server.
- Yes. On Signal Mesh the inherited frontend needed a full rewrite, so we rebuilt it with React, Vite, TanStack, Tailwind and Radix. Where an existing front end works, we keep it.
- We look at the existing application, available skills and long-term maintenance needs. The framework decision is explained as part of the technical plan.
- A defined scope can be quoted after discovery, with estimates per module so you can cut scope without cutting quality. An evolving product can use a dedicated squad with an agreed budget. We confirm the billing model before starting.
- You do. We work in your repository, and the components and documentation stay with your team.
