The web development landscape moves fast, and the gap between a "good enough" web app and a high-performance one is now measurable in revenue. At MPCS, we've settled on a stack that lets us ship quickly, scale without rewrites, and keep SEO and Core Web Vitals green from day one. Here's what we use and why.

The modern MPCS stack

  • React + Vite for fast, component-driven front-ends with instant hot-module reloading.
  • Tailwind CSS for a consistent, maintainable design system without dead CSS.
  • Serverless APIs (FastAPI or Node) that scale to zero and bill per request.
  • Postgres + managed storage for relational data and file handling.
  • Edge delivery for static assets and SSR where it improves time-to-first-byte.

Performance is a feature

We treat Core Web Vitals as acceptance criteria, not an afterthought. That means lazy-loading below-the-fold content, serving images in WebP with explicit dimensions to prevent layout shift, and code-splitting routes so the initial bundle stays small.

If your Largest Contentful Paint is over 2.5 seconds, you're losing conversions you can't see.

SEO built into the architecture

SEO isn't a post-launch task. We bake it in: semantic HTML5 structure, unique meta and Open Graph tags per route, JSON-LD structured data, canonical URLs, and a sitemap that updates automatically. For content-heavy sites, server-side rendering ensures crawlers see fully-formed pages.

Structured data that matters

We implement schema for Organization, WebSite, BreadcrumbList, and TechArticle wherever relevant. This is what turns a page from "indexed" into "eligible for rich results."

When to choose SSR vs. SPA

For dashboards and authenticated apps, a client-side SPA is fine. For anything that needs to rank — marketing sites, blogs, landing pages — we render on the server or at build time. The rule is simple: if a human or a crawler needs to read it, render it.
