Our Process

How we build step by step

A structured process ensures nothing gets missed, from initial discovery to a fully optimized Node.js launch.

  1. 01 Discover

    Discovery & Requirements Mapping

    User flows, database schema, third-party integrations, and technical requirements mapped out before a single line of Node.js is written.

  2. 02 Architect

    Application Architecture & SEO Strategy

    Service design, database schema, caching layer, and an SEO/SSR plan decided up front, so the application is fast, crawlable, and easy to extend.

  3. 03 Build

    Application Development & QA

    Secure, maintainable Node.js built with modern frameworks and patterns, tested across browsers, devices, and edge cases before it ever reaches staging.

  4. 04 Launch

    Launch & Optimization

    Server and query performance audits, Core Web Vitals checks, analytics setup, and deployment. Plus 30-day post-launch support for refinements.

Client Voices

What it's like to work with us

We measure success in load times and rankings, not just how a page looks. Here's what a few clients had to say.

Our old application took nine seconds to load on mobile because nobody had touched the query layer in years. The rebuild on Node.js came in under two, and our organic traffic more than doubled.
Ananya Kapoor
Head of Product, WooCommerce
They handed off a Node.js and TypeScript codebase our own engineers actually enjoyed working in, with modules that made every new feature faster to ship.
Rohan Mehta
Founder, Meridian Boutique
Migrating our legacy application to Node.js felt daunting, but the transition was seamless and load times dropped almost overnight.

Common questions

Anything else on your mind? Drop us a message at info@sitefiy.com

Yes, when it's set up right. Node.js frameworks like Next.js support server-side rendering out of the box, which means search engines get fully-formed pages without needing to execute client-side JavaScript, historically one of the more reliable setups for SEO. Combined with clean URLs and proper metadata, Node.js gives you both speed and search visibility.

Express suits lightweight APIs and services where you want minimal structure. Nest.js suits larger applications where you need enforced architecture, dependency injection, and testability. Next.js suits content-heavy or public-facing sites where server-side rendering and SEO matter most. We'll recommend the right fit during discovery.

A Node.js marketing site typically takes 3–6 weeks; a full Node.js web application or SaaS product usually takes 8–16 weeks depending on scope. We share a detailed timeline in our proposal before development begins.

We profile the event loop for blocking operations, add caching layers like Redis and CDN edge caching, optimize database queries, and run Lighthouse audits against Core Web Vitals throughout development, not just as a final step before launch.

Yes. We migrate legacy PHP, Java, or unframeworked codebases to modern Node.js and TypeScript, either incrementally alongside the existing application or as a full rebuild, with a plan designed to avoid downtime for the business relying on it.

Yes. Node.js is well suited to real-time features, and we build WebSocket-based chat, live dashboards, and notification systems as part of custom application builds.

Yes. Upon receipt of final payment, full IP and the complete codebase transfer to you through your own Git repository and hosting account, no vendor lock-in.

We offer optional retainers for continued feature development, Node.js version upgrades, security patching, and bug fixes after launch. It's entirely opt-in, not bundled by default.
