The challenge
Where teams get stuck
The problems we're most often brought in to solve.
- 01
Legacy front end resists change
An ageing Angular or jQuery interface is slow to change and increasingly difficult to staff.
- 02
No shared component library
Components are built ad hoc, so the interface looks and behaves inconsistently.
- 03
Fragmented state management
Data fetching and state logic are scattered across components, causing defects and slow screens.
Overview
React & Next.js Engineering at VulcanTech
React and Next.js development is the engineering of component-based web front ends in TypeScript, with Next.js adding server rendering and routing. VulcanTech builds and modernises front ends, from migrating legacy jQuery or Angular interfaces to establishing typed component libraries with full test coverage. Next.js is our default where routing and search matter; a Vite single-page application is often the simpler choice for internal tools and dashboards.
Key deliverables
- Typed component library with Storybook documentation
- State management architecture
- Unit and integration test suite in Vitest
- Migration roadmap for legacy screens

Our process
How we deliver
A delivery process you can see into — from first workshop to production support.
- 01
Discovery
A focused working session on your objectives, constraints and existing systems. It concludes with a scoped proposal and a clear view of value, risk and effort.
- 02
Architecture & planning
We agree the target architecture, data model and integration approach before product code is written, and secure your sign-off.
- 03
Iterative delivery
Working software reaches a staging environment on a regular cadence, giving stakeholders continuous visibility and the ability to steer priorities.
- 04
Assurance & hardening
Automated testing, accessibility and performance budgets, and a security review are completed before anything reaches production.
- 05
Launch & continuity
We manage cutover and remain engaged through an agreed support period, with a structured handover to your teams or ongoing operation by ours.
Engagement models
Work with us the way that suits you
Outcome-based delivery
A defined scope, timeline and commercial model agreed after discovery. We own delivery risk against the agreed outcomes.
Best for: Well-defined initiatives, MVPs and first releases
Dedicated product teams
A cross-functional pod — engineering, design, QA and delivery leadership — aligned to your roadmap and scaled as priorities change.
Best for: Long-term product development and evolving roadmaps
Team extension
Senior engineers embed in your organisation, work inside your processes and report to your leaders — on contracts that assign all IP to you.
Best for: Adding specialist capability without growing headcount
