Interfaces that stay fast as they grow
We build front-ends for complex products, where choices about architecture, state, and rendering decide how fast your team can keep shipping. From prototype to performance tuning.
We start with your problem, not the framework, the sluggish UI, the unmaintainable component sprawl, the redesign that stalled, and tell you honestly what it takes to fix it.

Front-end architecture & modernization
Legacy code becomes a liability that slows every new feature, and rewriting a massive jQuery or AngularJS monolith from scratch is rarely a sound business move. We refactor monolithic front-ends into modern, component-based architectures incrementally, part of our broader software development work, so you keep shipping value while paying down technical debt.
How we help
Our teams rely on the strangler-fig pattern to migrate applications to React, Vue, or Angular piece by piece. We introduce build tools such as Vite and Webpack, enforce strict typing with TypeScript, and set up CI/CD pipelines. You end up with a modernized codebase that’s testable and extensible, with none of the big-bang rewrite risk.

Scaling a complex front-end on a single monolithic codebase eventually creates gridlock, where engineers end up blocking one another. We decouple the application into independently deployable domains to restore development velocity for your teams.
How we help
We use module federation to stitch distinct features together at runtime, so teams can deploy updates without waiting on anyone else. We set governance models for shared dependencies to prevent bundle bloat while keeping the experience cohesive. The result is a unified interface that feels like one product to users but deploys like a collection of microservices.
Teams shouldn’t be rebuilding buttons and form inputs for every new feature, and inconsistent UI is a clear symptom of wasted engineering hours. We build reusable component libraries that enforce design consistency and speed up development right across your organisation.
How we help
Our engineers create documented component libraries in Storybook, backed by strict versioning and governance, with theming tokens and accessibility primitives set at the root level. So your developers can stop debating pixels and start shipping features by assembling pre-validated, dependable building blocks instead.
The old trade-off between search-engine optimization and interactivity is a thing of the past. Traditional single-page apps sacrifice rankings and initial load speed for interactivity; we build hybrid applications on frameworks such as Next.js that deliver the best of both worlds.
How we help
We architect solutions with server-side rendering for instant first paint and SEO, then hydrate into a fully interactive application on the client. We add incremental static regeneration to serve dynamic content at static speeds. So you get an application that ranks well on Google and still feels instant to the user.
Complex apps fall apart when data flow turns unpredictable. As features multiply, managing state across hundreds of components breeds bugs that are nearly impossible to reproduce. We put in robust state-management architectures that keep data consistent without a performance penalty.
How we help
We select the right pattern for the job, whether that’s Redux for global transactional state, TanStack Query for server-state synchronization, or atomic state for high-performance UI updates. We separate business logic from UI components to make the application testable, predictable, and easier to refactor as requirements evolve.
Performance is a feature, not an afterthought, slow-loading pages drive users away and drag down search rankings. We optimize front-end performance by analysing the critical rendering path, removing render-blocking resources, and putting aggressive caching strategies in place.
How we help
Our engineers profile applications with Lighthouse and WebPageTest to target Core Web Vitals. LCP, CLS, and INP. We implement code splitting, lazy loading, and image optimization pipelines, and we trim JavaScript execution time to improve Time to Interactive. So your application performs on low-end devices, not just developer workstations.
Manual testing is the bottleneck that quietly kills release velocity, if you depend on people to click through every screen before a deploy, you simply can’t keep shipping fast. We build automated testing pipelines that catch regressions before they merge, not after they launch.
How we help
We build end-to-end testing suites in Playwright or Cypress that simulate real user workflows, and we add visual regression testing to catch the pixel-level layout shifts unit tests miss. This shifts quality left, giving your developers the confidence to deploy to production even during high-risk windows.
Building without validation leads to costly rework down the line. We validate workflows before a single line of code is written, creating interactive prototypes and running usability testing so engineering effort stays focused on the right problems.
How we help
Our designers use Figma to create high-fidelity mockups and documented developer handoffs. We run user research and analyse session data to iterate on the designs as we go. You end up with a user interface grounded in actual user behaviour, not assumptions.
Front-ends we've shipped
View all case studiesThe stack we build with
We build on the framework that fits your product and team, not the one making noise this quarter. The goal is an architecture your engineers can extend and maintain for years.
We build on the framework that fits your product and team, not the one making noise this quarter. The goal is an architecture your engineers can extend and maintain for years.
We set up fast, modern build tooling so local dev stays quick and production bundles stay lean, with config kept sensible enough that new engineers pick it up without a manual.
We fit the state approach to the problem, global, server, or local, so data stays consistent without dragging the UI down.
We test at the levels that catch real regressions, unit, integration, end to end, wired into CI so nothing broken gets merged.
We watch Core Web Vitals and real-user metrics in production, so slowdowns and errors surface before a customer ever feels them.
We build on accessible, well-maintained component foundations, or your own design system, for consistency without reinventing the primitives.
We connect the UI to your APIs with caching, retries, and error handling built in, so data feels instant and holds up.
We work in your branching model and review flow, with CI gating every change, so releases stay routine and traceable.
We work from your design files and prototypes, validating flows early and keeping a tight, documented handoff from design to code.
Our front-end development process
Eleven steps, run in order, step through the sequence from first review to production.
Front-end experts, AI-augmented
These are the AI coding tools our engineers use to ship faster and keep code clean, distinct from the AI systems we design and build for you.
We use these tools inside strict guardrails, every line is reviewed by a person. See how we build →
Senior Front-end engineers
Engineers with real, hands-on front-end experience who take ownership of the work, not juniors learning on your budget.
Production-grade delivery
We take work from prototype to production, with testing, monitoring, and clean handover, not demos that stall after the pitch.
Security & compliance
Safeguards from day one. We build to and align with the standards regulated industries expect, including HIPAA, SOC 2, and ISO 27001.
We've delivered front-ends across healthcare, fintech, proptech, logistics, and more.
