Web Development in San Diego: Next.js apps built to ship and to last

DevX Group LLC builds Next.js marketing sites, web apps and SaaS dashboards for startups and small teams. Based in San Diego and led by founder Max Sheikhizadeh, priced at $95 to $175 per hour, with most first releases delivered in 4 to 12 weeks. One repo, one deploy, tests included.

What we build

Most agency sites and most homegrown apps fail the same way: slow first paint, no tests, and a codebase nobody but the original developer can touch. We build the opposite on purpose, using the stack we run our own products on.

  • Marketing sites that load fast and rank: server-rendered pages, real metadata and structured data, images sized and served correctly instead of guessed at.
  • Web apps and dashboards: the internal tool or customer-facing product your team actually uses every day, built with the same rigor as a shipped product.
  • SaaS with auth, billing and admin: sign-up, subscriptions, and an admin panel that lets you see and fix what a customer is seeing.
  • E-commerce: checkout, inventory and order management wired to a real payment processor, not a page that promises "coming soon."

How we keep it honest

Every page ships against numbers, not opinions: Largest Contentful Paint under 2.5 seconds, Interaction to Next Paint under 200 milliseconds, Cumulative Layout Shift under 0.1. We measure these before launch, not after a customer complains.

Accessibility is checked, not assumed: keyboard navigation, contrast, and screen-reader labels are part of the build, not a pass at the end. And the codebase stays boring on purpose: one repository, one deploy pipeline, and tests on the paths that lose you leads or money if they silently break.

Who this is for

Founders who need a marketing site or a first product built right the first time, and teams whose current site or app has become too slow or too fragile to keep extending. If you are in San Diego we can meet in person; most of our clients work with us remotely across US time zones.

What we build with

Named tools, and the reason each one is on the list.

  • Next.js 16 App Router

    Server rendering by default, so pages are fast without extra tuning.

  • React 19

    The current React, with the server-first patterns Next.js is built around.

  • TypeScript strict

    Catches a wrong assumption at compile time instead of in production.

  • Tailwind v4

    Styling that stays in the markup, so nobody has to hunt a separate CSS file.

  • Supabase or Postgres

    One relational database for the app, auth and the admin data.

  • Vercel

    Deploys on every push, with preview URLs for every change before it ships.

  • Stripe

    Billing and checkout that handles the edge cases we would otherwise have to write ourselves.

  • Playwright

    End-to-end tests that click through the app the way a customer actually would.

How an engagement runs

Bi-weekly demos throughout. Code, configs and runbooks are yours at acceptance.

  1. 01Week 1

    Discovery and scope

    We map the pages, the data model and the integrations, and agree on a fixed scope before any code is written.

  2. 02Weeks 2 to 6

    Build

    The app takes shape in bi-weekly demos, so you see real progress and can redirect early instead of at the end.

  3. 03Weeks 6 to 9

    Hardening

    Core Web Vitals, accessibility, and end-to-end tests on the flows that matter, run before launch, not discovered after it.

  4. 04Weeks 9 to 12

    Launch and 30-day stabilization

    Production release with monitoring, then 30 days of on-call fixes while real traffic arrives. Code and access are yours at acceptance.

Proof, not promises

Shipped work that shows this service in practice.

Questions we get asked

How much does a website or web app cost in San Diego?

DevX Group LLC bills $95 to $175 per hour depending on the engagement tier, published on our pricing page. A marketing site or a focused first version of a web app usually takes 4 to 12 weeks. We quote a fixed scope after week-one discovery so the total is known before build starts, not guessed at from a form.

Why Next.js instead of WordPress or Webflow?

WordPress and Webflow are fine for a page that never changes. A Next.js site or app is code you and your team fully own, with no plugin updates that can break the site and no platform fee that scales with traffic. It also loads faster by default, which matters for both Core Web Vitals and search ranking, and it grows into a real application instead of hitting a wall the moment you need custom logic.

Who actually writes the code?

Founder Max Sheikhizadeh leads every engagement and writes the architecture and the code that matters. For larger builds, our partner studio scales the team so timelines stay realistic without handing the project to a stranger. You always know who is working on your project and can talk to the person writing the code, not an account manager.

Do we own the code when the project is done?

Yes. At acceptance you get the full repository, deploy access, and any credentials the app depends on. Nothing is licensed back to us, and nothing requires us to keep hosting or maintaining it, though we offer stabilization and ongoing support if you want it. The goal is a codebase your own team, or another agency, can pick up and read.

Is SEO built in or is it an extra?

Built in. Every page we ship gets server-rendered metadata, structured data where it applies, a sitemap entry, and images sized correctly instead of left to the browser to figure out. That is the same foundation this page uses. SEO work beyond the technical baseline, like content strategy or backlink building, is scoped separately because it is ongoing work, not a one-time build step.
