What We Build

SaaS Web Applications

We are a full build partner for SaaS founders, React component libraries, Node.js multi-tenant API layers, MongoDB schema design, and subscription billing via Stripe baked in from sprint one.

Consumer Web Products

Marketplaces, booking platforms, social tools, and on-demand services, we build React-powered products optimised for user engagement, Core Web Vitals performance, and conversion.

Real-Time Web Applications

Live dashboards, collaborative editing, messaging platforms, and event-driven notification systems, Socket.io and Node.js async architecture keep real-time features performant under load.

REST and GraphQL APIs

Backend services your web and mobile clients can depend on, versioned, documented, authenticated with JWT or OAuth2, load-tested, and deployed with CI/CD.

Progressive Web Apps

React PWAs that install from the browser, work offline via service workers, and support push notifications, closing the gap between web and native.

Next.js and SSR Applications

When SEO, page speed, or server-side data fetching matters, we extend the MERN stack with Next.js, delivering hybrid static and server-rendered React applications that rank and convert.

AI-POWERED

Delivered faster with AI tooling

We don't just write code; we orchestrate intelligence. By integrating Copilot-assisted generation and AI-driven automated testing, we reduce time-to-market by up to 40%.

Copilot-Assisted Generation

LLM-backed development to eliminate boilerplate delays.

AI Predictive Testing

Anticipating edge cases before they enter production.

Our Development Journey

A streamlined, transparent path from vision to launch.

Discovery and Architecture

1–2 weeks

We define your React component hierarchy, MongoDB schema, API surface, and infrastructure plan, producing a technical spec you review and sign off before design begins.

UI/UX Design

1–3 weeks

High-fidelity Figma designs mapped to a React component library. We design with composition in mind, every screen is a set of reusable components, not a static mockup.

Development

4–16 weeks

Two-week sprints with a working staging environment from sprint one. React frontend and Node.js backend developed in parallel using shared TypeScript interfaces.

QA and Performance Testing

1–2 weeks

Unit tests with Vitest, end-to-end tests with Playwright, MongoDB query profiling, Node.js load testing, Core Web Vitals audit, and OWASP Top 10 security review.

Deployment and Go-Live

3–5 days

Production environment provisioned, monitoring and alerting live, CI/CD pipeline active. We remain on-call for the first 48 hours post-launch.

Ongoing Maintenance

Ongoing

Performance monitoring, React and Node.js dependency updates, MongoDB index optimisation, and feature iteration. Full documentation and pipeline ownership handed over at project close.

Frequently Asked Questions

Why MERN over other JavaScript stacks?+

MERN gives you React component model — the most widely adopted UI framework in 2026. Paired with Node.js and MongoDB, it is a fully JavaScript environment where your whole team shares context.

What is the difference between MERN and MEAN?+

Both use MongoDB, Express, and Node.js. The difference is the frontend — React in MERN versus Angular in MEAN. React is more flexible and composable; Angular is more structured and opinionated.

Do you use Next.js as part of MERN development?+

Yes. For products where SEO or server-side rendering matters, we extend MERN with Next.js. We advise on whether a pure SPA or a Next.js hybrid is right based on your content strategy.

How long does MERN stack development take?+

MVPs are typically 8–14 weeks. Full products with complex React modules and integrations run 16–24 weeks.

Who owns the source code?+

You own everything. Full transfer at project close, with no retained rights or ongoing licence.
