WHAT WE DELIVER

Front-end development services we deliver

Interface work owned by engineers who have shipped it before, in the frameworks your team already uses.

Custom front-end development

Product interfaces built from your designs in React, Angular, Vue, or Next.js, wired to your APIs and your component library.

Single-page applications

Fast, stateful web apps with client-side routing and predictable state management, built to stay maintainable past version one.

Progressive web apps

Installable web experiences with offline support and push notifications, so you reach mobile users without shipping a native app.

Dashboards and data visualization

Analytics and reporting interfaces that render large datasets without freezing the browser, using D3, Recharts, or your charting library of choice.

Headless CMS front ends

Storefronts and marketing sites on Contentful, Sanity, or WordPress headless, so marketing publishes without a developer in the loop.

Front-end modernization

jQuery, AngularJS, and aging React codebases migrated screen by screen, with the product live the whole time.

QUALITY STANDARDS

Interfaces that pass the audits

Three things your front end gets measured on once it is live, and how we build for each.

Core Web Vitals optimization

Bundle splitting, image and font strategy, and render-path work, tracked in Lighthouse and field data until the numbers hold.

WCAG accessibility compliance

Semantic markup, keyboard navigation, and screen-reader testing against WCAG 2.2 AA, which is the standard US courts reference in ADA claims.

Search-friendly rendering

Server-side rendering or static generation where crawlers need it, so a rich front end never costs you organic traffic.

HOW WE ENGAGE

Three ways to add front-end engineers to your team

Staff augmentation

Senior front-end engineers added to your existing team, under your direction, in days rather than months.

Dedicated development teams

A front-end team working only on your product, self-organizing sprint after sprint while you set the roadmap.

Full project outsourcing

You hand over the scope and we deliver it under our management, covering design implementation, development, QA, and maintenance.

OUR PROCESS

How a front-end engagement starts

01

Discovery call

Your product, your designs, and where the interface slows you down (30 minutes).

02

Team proposal

Matched front-end engineer profiles in days, not weeks.

03

Interviews

You meet and approve every engineer.

04

Sprint delivery

Your tools, your workflow, live demos every sprint.

FAQ

FAQs about our front-end development services

01

How much do front-end development services cost?
Senior nearshore front-end rates run 30-50% below equivalent US salaries and agency fees. What you pay depends on team size, seniority mix, and engagement model. You get a transparent, line-item estimate on the first call, with no recruiting fees and no hidden overhead.
02

Can you work in our existing codebase and design system?
Yes, and that is how most engagements begin. Our engineers adopt your component library, your linting rules, and your branching model, then start with small pull requests so your team can see the quality before the scope grows.
03

How do you reduce front-end technical debt without pausing the roadmap?
We pay it down inside feature work rather than asking for a freeze. Each sprint carries a share of refactoring alongside the roadmap items, prioritized by the components that break most often, so the codebase improves while releases keep going out.
04

When does it make sense to rebuild the front end instead of refactoring it?
A rebuild is worth it when the framework is out of support, when the design system has been abandoned, or when every new feature requires touching the same fragile code. Below that threshold, an incremental migration screen by screen is cheaper and far less risky. We will tell you which one your codebase needs.
05

Which front-end frameworks do you work with?
React, Angular, Vue, and Next.js as the core, with TypeScript, Tailwind, and the testing tooling around them. We also maintain older AngularJS and jQuery codebases while migrating them. We staff for the stack you already run.
06

Do your engineers work directly with our designers?
Yes. They join design reviews, flag edge cases before the handoff, and build straight from Figma. When there is no designer on your side, our engineers work from your existing patterns instead of inventing new ones.
07

How do you handle accessibility and ADA compliance?
We build to WCAG 2.2 AA: semantic markup, full keyboard navigation, visible focus states, and screen-reader testing on real assistive technology, not just automated scans. For products already live, we start with an audit and a prioritized remediation plan.
08

Will a single-page app hurt our search rankings?
Not if it is rendered correctly. We use server-side rendering or static generation on the routes that need to be crawled and indexed, keep the client-side experience for the app itself, and verify the result in Search Console.
09

How fast can front-end engineers start?
We present matched profiles within days, you interview and approve them, and most engineers onboard in under 2 weeks. A US front-end hire typically takes 3 to 6 months from job post to first commit.
10

How much time zone overlap will we have?
Our engineers work across Latin America on US Central and Eastern time, which gives 6-8 hours of daily overlap. Design reviews, pairing sessions, and pull-request feedback all happen the same day instead of the next one.
11

How do you protect our IP and source code?
Every engagement runs on US-friendly contracts, with an NDA in place before the first call and full intellectual property assignment to you. Access to repositories and design files is role-based, and your work stays in your accounts under your control.
