Custom Web Development: Websites, Portals and E-Commerce

A website is the first system a customer uses before they decide to trust you with anything else. It has to load fast on a phone, read well to a search engine, work for someone using a screen reader, and keep working when a marketing team edits it every week. Those are engineering properties, and they are decided in the build, not in the design review.

InsightSol builds web properties the way it builds platforms: Next.js and React with a headless CMS your team edits, a design system that keeps every page consistent, server rendering for speed and search, and measurement built in. The same approach covers marketing sites, customer portals, e-commerce storefronts, and progressive web apps that install on a phone without an app store.

In brief

What does custom web development at InsightSol deliver?

Fast, editable, search-ready web properties on Next.js and React: marketing sites, customer portals, e-commerce storefronts, and progressive web apps, with a headless CMS for your editors and performance, accessibility, and visual checks enforced in CI.

  • A rendering strategy chosen per page, static for content and server-rendered for personalized views, for speed and search
  • A headless CMS with typed content models and preview, so editors change pages without a developer
  • Performance budgets, axe accessibility scans, and visual regression tests that fail the build before a user sees the problem
  • Commerce and portal flows on Stripe or your business systems through typed APIs

Who this is for

  • Marketing teams whose site is slow, hard to edit, or invisible to search
  • Companies that need a customer portal on top of their existing business systems
  • Brands moving to e-commerce or replacing a storefront that cannot be customized

What you receive

  • Next.js site or portal with a rendering strategy chosen per page
  • Headless CMS with typed content models, preview, and editor training
  • Design system and component library on Tailwind CSS
  • Commerce or portal flows integrated with your payment and business systems
  • Structured data, sitemaps, Core Web Vitals monitoring, and analytics events
  • Performance, accessibility, and visual regression checks wired into CI

Architecture pattern

How the system is put together.

The components we ship, in the order a request moves through them. Every boundary is typed, every failure path is designed, and every action is logged.

  1. 1

    Rendering strategy per page

    Static generation for content, server rendering for personalized or data-driven pages, and streaming where a page depends on a slow source, chosen per route for speed.

  2. 2

    Headless content layer

    A headless CMS with typed content models, preview, and scheduled publishing, so editors change pages without a developer and without breaking the layout.

  3. 3

    Design system and components

    A token-based component library on Tailwind CSS, so new pages are assembled rather than redesigned and the brand stays consistent across hundreds of pages.

  4. 4

    Commerce and portal services

    Catalog, cart, checkout, and account flows on Stripe or a commerce backend, and authenticated portals that read from your business systems through typed APIs.

  5. 5

    Performance, search and analytics

    Image and font optimization, structured data, sitemaps, Core Web Vitals monitoring, and analytics events wired to the actions that matter.

Failure prevention

Performance budgets in CI

Lighthouse and bundle-size checks run on every pull request and fail the build when a page gets slower.

Accessibility checks

Automated axe scans plus keyboard and screen-reader passes against WCAG 2.2 AA before every release.

Content validation

Typed content models reject a broken entry at publish time rather than rendering an empty section to visitors.

Visual regression tests

Screenshots of key pages are compared on every change, so a CSS edit cannot silently break a layout.

Targets we design to

  • <2.5s

    Largest Contentful Paint on mobile, the Core Web Vitals threshold

  • AA

    WCAG 2.2 conformance verified before launch

  • 90+

    Lighthouse performance score on content pages

How the engagement runs

From audit to handover.

Web projects begin with a short discovery: the pages that matter, the systems they read from, the editors who will maintain them, and the metrics the site must move, usually conversion, speed, and search visibility. Design and content modeling run in parallel with the component library, pages ship in order of traffic, and the old site is retired only after redirects and search rankings are verified.

Questions about this service

Yes. We design in the same system we build in, so what you approve is what ships. If you already have a design agency, we work from their files and keep them in the loop on what the build changes.

A headless CMS chosen for your editors: typed content models, preview, and scheduled publishing are the requirements. We recommend the option that fits your team's workflow and budget and keep the content portable, so you are never locked in.

Not if it is managed. We map every old URL to a new one, keep the structured data and metadata, verify the redirects before cutover, and watch Search Console in the weeks after launch.
