Our Process

How we build custom, step by step

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

  1. 01 Discover

    Discovery & Requirements Mapping

    Business goals, target keywords, competitor benchmarking, and technical requirements mapped out before a single line of custom code is written.

  2. 02 Architect

    Custom Architecture & SEO Strategy

    Database schema, URL structure, information architecture, and an on-page SEO plan designed together, so every custom-built page is structured for search engines and users alike.

  3. 03 Build

    Hand-Coded Development & QA

    Clean, semantic, hand-written code, no drag-and-drop builders or bloated plugins, built for speed and accessibility, and tested across browsers and devices before it ever reaches staging.

  4. 04 Launch

    Launch & Optimization

    Performance tuning, Core Web Vitals checks, analytics setup, and search console submission. Plus a 30-day post-launch support window for refinements.

What it's like to work with us

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

Our old templated site took nine seconds to load on mobile. The custom rebuild came in under two, and our organic leads have nearly tripled since.
Ananya Kapoor

They handed off a custom codebase our own engineers actually enjoyed working in, and the SEO groundwork paid off within the first quarter.

FAQ

Common questions

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

Custom web development means your site or app is hand-coded from the ground up on frameworks like React and Next.js, rather than assembled from a pre-built theme or page-builder. You get full control over performance, functionality, and design, with no plugin bloat or template limitations holding the build back.

A custom marketing site typically takes 3–5 weeks; a custom web app, dashboard, or e-commerce build usually takes 6–14 weeks depending on scope. We share a detailed timeline in our proposal before development work begins.

Technical, on-page SEO is engineered directly into every custom build we ship, semantic markup, meta tags, structured data, sitemap, and Core Web Vitals optimization from day one, not bolted on afterward.

Custom code makes sense for anything with unique business logic, dashboards, POS integrations, complex workflows, or performance needs a template can't meet. If your project is closer to a standard content site or storefront, we'll say so during discovery rather than pushing a custom build you don't need.

Yes. We build custom admin dashboards, client and employee portals, and point-of-sale or inventory systems, either fully custom or integrated with existing tools. These are typically scoped under our Enterprise package.

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

We can set up hosting on your preferred provider and offer optional maintenance retainers for updates, monitoring, and security patches. It's entirely opt-in, not bundled by default.

Each package includes a set number of revision rounds (see uxd-pricing). A "revision round" is a consolidated batch of feedback, not individual change requests. Anything beyond the included rounds is billed as a Change Request at our day rate.
