React & Next.js applications
Application interfaces with deliberate rendering and data-loading choices — server-rendered pages where discovery matters, interactive clients where the task needs it.
Interfaces builtto be trusted.
The frontend is where your product is judged. We engineer React and Next.js interfaces with the component discipline, accessibility and performance work that keep them dependable as they grow.

The right scope.
Built around your needs.
Start with the problem that matters. Combine the capabilities your project needs, with boundaries agreed before the build.
Design systems & component libraries
Reusable, documented components with consistent states — hover, focus, disabled, error — so new screens extend the system instead of diverging from it.
Accessibility engineering
Keyboard operation, visible focus, labelled controls, sensible landmarks and reduced-motion support verified as part of the work, not appended to it.
Frontend performance
Bundle discipline, caching and loading behaviour measured on mid-range phones and average connections — the devices your users actually hold.
States first, screens second.
A reference frontend structure. The component system and the screens it composes are built and verified as separate disciplines.
Foundation: its responsibility
Give every screen the same type, spacing, colour and interactive states, so the product stays coherent as it grows.
What to review
Check hover, focus, disabled and error states exist for every component, and that new UI cannot bypass the system.

Illustrative applications to help shape your brief. These are possible project scopes, not customer case studies.
The starting point
A backend exists, but the screens are inconsistent, slow and hard to use on phones.
The approach
Define the core journeys and their states first, build a small component system, then rebuild the screens against it with keyboard and touch checks.
What the work can produce
A consistent, accessible interface with a component library and documented patterns.
Start where
your project is.
The first step depends on what is already known. These starting points help define an engagement; scope, price and timing are agreed separately.
Explore an uncertain idea
The problem is clear, but the approach is not.

What you take forward
A bounded experiment, findings and a recommendation on what to validate next.
A prototype is not a production-ready service.
Deliver a defined scope

What you take forward
Agreed deliverables, verification evidence and operating instructions for the scoped release.
Changes to scope need an explicit decision on cost and timing.

What you take forward
A prioritized backlog, reviewed changes and an agreed maintenance or support boundary.
Coverage, response targets and access are agreed per engagement.
A clear path.
Through the work.
Scope and deliverables are agreed for each project. These stages guide the conversation.
- 1
Map journeys and states
Agree the tasks, roles, empty states and error paths before writing components.
- 2
Build the system, then screens
Create components with their states, then compose screens; review in the browser at every step.
- 3
Verify with real constraints
Check keyboard, touch, slow networks and content of awkward length; document what was tested.
One system, verified states
Technology is a scoping decision. These are relevant tools and building blocks to discuss against your existing systems, operating constraints and maintenance needs.

What should be checked
before handover.
Turn quality expectations into reviewable evidence. The exact checks and responsibilities belong in the project scope.
Every state designed
Confirm loading, empty, error, disabled and success states exist for each component and journey.
Keyboard & focus
Operate every journey with the keyboard alone; check focus visibility, order and trap-free dialogs.
Performance on real devices
Measure load and interaction on a mid-range phone and an average connection, against the agreed budget.
Before
we begin.
Practical answers to help turn your idea into a scope everyone understands.
Do you work from our existing designs?
Yes. Figma designs or an existing product are the starting point. Where designs omit states — loading, empty, error — we surface those gaps early, because they are where interfaces actually fail.
React, Next.js — what about other frameworks?
Jainil's experience is deepest in React, Next.js, TypeScript and Tailwind CSS. A different stack can be discussed when your existing system requires it, with maintenance realities stated plainly.
Is accessibility included or extra?
Included. Keyboard operation, focus visibility and labelled controls are engineering requirements, not a separate phase. Full audits against specific standards can be scoped separately.
Often better together.
