Enterprise web development with React, Next.js, Angular and Vue
High-performance web applications, optimized for SEO and accessibility, ready to scale. Fixed budget, functional demos every 2 weeks, and code 100% yours from the first commit.
Web development is building applications that live in the browser: from an internal dashboard or customer portal to a B2B platform with thousands of concurrent users.
We use the right framework for your problem — Next.js when SEO and server-side rendering matter, React or Vue for rich interfaces, Angular for complex enterprise systems — without tying you to trends. We are a software factory founded in 2018 (Monterrey + Texas, CMMI Level 2, 5.0★ on Clutch) with more than 200 projects delivered. We work with a fixed budget defined before we start and deliverables every 2 weeks, so you see real progress from week 2 instead of a black box.

When you need it
What it includes
Frontend architecture
We define component structure, routing, state management and the rendering strategy (CSR, SSR or SSG) for your business case, documented with architecture decision records (ADRs). The base the team builds on without rewriting three months in.
Design system & UI
Reusable components, design tokens and consistent patterns (documentable in Storybook), with prototypes validated with stakeholders before any production code is written. So every new screen looks and behaves the same, and ships faster.
SEO & performance
Server-side rendering or SSG so search engines index your content, Core Web Vitals optimization, lazy loading, optimized images, CDN and metadata/structured data (JSON-LD) for search engines.
WCAG 2.1 AA accessibility
Keyboard navigation, contrast, ARIA roles, visible focus and screen-reader testing built into the QA cycle — not patched on at the end. Important if you have government or regulatory requirements.
State & data fetching
Client and server state management, caching, pagination, and well-handled loading and error states, so the app feels fast and predictable even on slow connections or with slow APIs.
Backend & API integration
REST or GraphQL consumption, API contracts (OpenAPI), authentication (OAuth2/JWT) and connection to your existing systems (ERP, CRM, payments). If you have no backend, we build it — we are a full factory, not just front-end.
QA & security with ARIA
Functional, load, regression and security testing (OWASP Top 10) backed by our internal ARIA platform, integrated into the pipeline so each change is validated before merge.
Observability & error monitoring
Production error monitoring (Sentry-style), real-user performance metrics (RUM) and alerts, so you find out about a problem from the dashboard and not from an angry customer.
How we work
Architecture
We define components, routes, global state and rendering strategy. Deliverable: an architecture document with ADRs, a fixed budget and a timeline before coding.
UI/UX
Design system, reusable components and an interactive prototype validated with your users and stakeholders. Deliverable: an approved prototype and a base design system, so what's approved is what gets built.
Agile development
2-week sprints with mandatory code review, automated testing and CI/CD from day 1. Deliverable: a functional increment deployed to staging and a live demo at the end of each cycle.
Optimization
Performance audit, Core Web Vitals, lazy loading and CDN, with security (OWASP Top 10) and load QA on the ARIA platform. Deliverable: a performance and security report with findings remediated.
Deploy & go-live
Controlled launch, domain/CDN setup, error monitoring and a rollback plan. Deliverable: the application in production with observability live.
Handoff & support
Handoff of the full repository, documentation and knowledge transfer. Deliverable: code that's 100% yours from the first commit, access and 90 days of support — with no vendor lock-in.
Tech stack
The tools and platforms we build it with — chosen for your problem, not for hype.
Frequently asked questions
What framework do you recommend for my project?
It depends on requirements, not trends. Next.js when SEO and server-side performance are critical; React or Vue for dashboards and rich interfaces; Angular for complex enterprise apps with large teams. We define it together in the discovery phase, with technical arguments rather than preferences.
Do you include UI/UX design?
Yes. Before development we create the design system and interactive prototypes and validate them with your stakeholders. This reduces rework: what gets approved in the prototype is what we build.
Does the client own the code?
Yes, 100%. All code, documentation, access, repositories and environments are yours from the first commit. No vendor lock-in: if tomorrow you want to switch providers, you have everything you need.
How do you ensure SEO and accessibility?
With server-side rendering or static site generation so search engines index your content, Core Web Vitals optimization, and WCAG 2.1 AA compliance verified inside the QA cycle with our internal ARIA platform — not patched on at the end.
Can you take over a project another team started?
Yes. We do code audits, take over half-finished projects and stabilize inherited applications, regardless of the stack. We start by understanding the real state of the code and the risks, give you an honest assessment, and propose a plan from there — sometimes continuing what exists, sometimes refactoring in parts. We decide with data, not by assuming the answer up front.
How long does an enterprise web application take and cost?
It depends on scope. An application with a focused set of screens usually takes 8 to 14 weeks; an enterprise platform with many roles and integrations takes longer. It is quoted with a fixed budget defined in the discovery phase — no hourly billing, no ambiguous scope — and we deliver demos every 2 weeks. A 3-minute assessment gives you an investment range based on your real requirements.
