Front-end development
services for
SaaS teams
Senior React, Angular and Next.js engineers who take a SaaS product from the first screen to release and keep shipping after launch. We build the UI, the design system, the performance budget and the accessibility layer, as your front-end team or inside the one you already have. 100+ SaaS products delivered over 10+ years, a 4.9/5 rating on Clutch, a proposal within 3-5 business days and a kick-off in 2-4 weeks.

Front-end work we can show you
All case studiesWhat our front-end development services cover
Six things a SaaS front end needs and one team that does all of them. Each links to the specialised page where that work has its own process and case studies.
Design systems and SaaS UI design
A component library with tokens, states and documentation, so every new screen looks like the product and ships faster than the last one. Our SaaS design team works in the same sprint as the engineers, not a handoff ahead of them.
Performance and Core Web Vitals
Bundle budgets, rendering strategy, image and font loading, caching. We bring LCP, INP and CLS into the green and keep them there with monitoring. Existing product with a red field report? Start with Core Web Vitals optimization.
Accessibility
WCAG 2.2 AA as a build standard rather than a retrofit: semantic markup, keyboard paths, focus management and screen-reader testing. For a live product, a frontend audit gives you the gap list and the fix order first.
Migrations and modernization
AngularJS to Angular, class components to hooks, Create React App to Next.js, jQuery to React. Incremental and module by module, with the product live throughout. See application modernization and React migration services.
Staff augmentation
Vetted senior front-end developers who join your team, your process and your tools, with an interview before they start. Hire React developers or hire Angular developers for the quarter your roadmap needs them.

The stack we build front ends with
Five technologies cover almost every SaaS front end we are asked to build. We go deep on them instead of wide on everything, and the testing and tooling around them (Vitest or Jest, Playwright, Storybook, CI pipelines) come as standard.
- React
- Hooks, React Query, Zustand or Redux where state demands it, Storybook for the component library.
- Angular
- Standalone components, signals, NgRx for complex state, Nx workspaces for enterprise monorepos.
- Next.js
- App Router, server components and server actions, ISR and edge caching for SEO-critical pages.
- TypeScript
- Strict mode on every project; types shared with the backend through generated clients.
- Tailwind CSS
- Utility-first styling on top of design tokens, with a documented component layer above it.
How a front-end project starts with TFC
Product teams at SaaS companies hire us when the front end has become the bottleneck: a dashboard-heavy product that needs to scale, a legacy UI due for a rebuild, a marketing site that fails Core Web Vitals, or an in-house team that needs senior front-end capacity without a six-month hiring cycle. Most engagements start with a founder, CTO or VP Engineering, a working product and a deadline.
- 01
Discovery call
A 30-minute call with our founder or COO: your product, where the frontend hurts today, team setup, timeline. No slides, no sales script.
- 02
Proposal in 3-5 business days
Scope, architecture notes, team composition and a phased plan with milestones. You see what gets built, in which order, and by whom.
- 03
Kick-off in 2-4 weeks
Paperwork, access and onboarding happen in parallel, so the team starts on sprint one with the plan already agreed.
Three ways to work with us
Project delivery
We own the frontend end to end: architecture, UI, testing, release. Fixed scope, phased milestones, one accountable team.
Dedicated team
A stable squad of senior front-end engineers (plus design and QA when needed) embedded in your product organisation. You steer the backlog, we run delivery.
Staff augmentation
Individual vetted front-end developers join your existing team, your process and your tools, with an interview before they start. See how hiring front-end developers works
How we deliver a front-end project
Discovery and audit
A 30-minute call with our founder or COO, then a short review of your codebase, designs and analytics. You get a written scope, the risks we see and the team we propose, within 3-5 business days.
Architecture and design system
Component structure, state and data-fetching approach, performance budget, accessibility standard and the first slice of the design system are agreed before sprint one, so the team builds on decisions rather than assumptions.
Sprints with weekly demos
Two-week sprints, a demo every week and a preview deployment for every pull request. You review working software, not status reports, and reprioritise the backlog whenever the product needs it.
Quality gates before every release
Type checks, unit and end-to-end tests, Lighthouse and accessibility runs in CI, and a senior review on every merge. Nothing reaches production on one person's say-so.
Launch and after
Release support, monitoring of Core Web Vitals and errors, and a retainer or dedicated team if you want the same people to keep shipping. Most of our client relationships run for years, not one project.
Senior engineers first, AI second
AI-augmented delivery is how we work, not a separate service. Every developer at TFC has 5+ years of commercial experience and uses AI tools for the repetitive parts of the job, so the senior hours go to architecture, UX and business logic. Every AI-generated line is reviewed, tested and owned by a named engineer.
AI-assisted scaffolding
AI-powered review in CI
Generated test coverage
Faster debugging and profiling
