The Stack

One Focused Stack, Built to Last

Every project lives inside the same React ecosystem — no Shopify themes, no WordPress plugins, no surprise frameworks. Depth over breadth, on purpose.

Next.js

Server components, App Router, image optimization, edge rendering. The default for production-grade React sites and apps.

React Router v7 (Remix)

Full-stack React framework with nested routing, loaders, and progressive enhancement. Ideal for content-heavy sites that need real interactivity.

React 18+

Concurrent rendering, server components, and a deep, opinionated component vocabulary I have shipped at scale.

Postgres

Relational, ACID-compliant, and batteries-included. Hosted via Neon, Supabase, RDS, or your provider of choice.

Custom CMS Layer

Payload CMS, Sanity, or a fully bespoke admin built on the same React stack — so editors and developers share one codebase.

Vercel / Fly / Railway

Deployments wired into Git. Preview environments per pull request, instant rollbacks, and clean CI from day one.

Why Custom

Custom Code Outperforms Page Builders

Page builders are great for getting started. They are not great for what comes next — performance, integrations, and a UX that fits your actual workflow. Custom builds solve those problems by default.

Performance That Compounds

A focused React build runs leaner than any plugin-stuffed CMS. Faster pages convert better, rank better, and cost less to host.

No Plugin Roulette

WordPress and Shopify rely on third-party plugins that break, get abandoned, or open security holes. Custom code means a single, owned dependency tree.

It Behaves How You Want

When the CMS does not match the workflow, the workflow loses. A custom admin can mirror exactly how your team actually edits, reviews, and ships content.

Real Engineering, Not Theme Hacking

Type-safe schemas, migrations, tests, and observability — the things that keep a product alive past year one.

SEO-Native Engineering

Built on a Bulletproof SEO Foundation

Most agencies treat SEO as something you bolt on later. RedSEO is a working SEO agency first — so the same team that runs Utah SEO retainers writes the code on every custom build. Technical SEO is engineered in from the first commit, not retrofitted six months after launch.

Core Web Vitals

LCP, INP, and CLS optimized at the framework level — Next.js Image, font preloading, and route-level code splitting tuned for green scores out of the gate.

JSON-LD Schema

Organization, Product, Article, FAQ, Breadcrumb, and Service schema — typed, version-controlled, and emitted from the same React tree that renders the page.

Real Server-Side Rendering

Crawlers receive HTML, not a hydration shim. Every page is indexable from the first request, with proper status codes for missing routes.

Semantic, Accessible Markup

One H1 per page, logical H2–H4 hierarchy, ARIA where it actually helps. WCAG-friendly markup is part of the spec, not a retrofit.

Indexable URL Architecture

Clean paths, canonical tags, hreflang where relevant, and zero duplicate-content traps. robots.txt and llms.txt shipped from day one.

Auto-Generated Sitemaps

XML sitemaps that include CMS-driven content, regenerate on publish, and ping search engines on update — no plugin, no cron drift.

Editor-Controlled Meta

Title, description, Open Graph, and Twitter cards exposed as fields in the CMS, with sensible defaults and inline preview built in.

Performance Budget in CI

JavaScript bundle size and image weight have hard ceilings checked in CI. Performance regressions fail the build before they reach production.

Want the rankings handled too?

Bundle the build with a Utah SEO retainer.

Same team, one contract. Custom Next.js or React Router v7 build on the front end, content and link-building retainer on the back end. Local Utah businesses get an extra edge in the Map Pack and local SERPs while the new site is still being built.

How It Works

How a Custom Web Development Service Engagement Works

Five phases, written into the contract, with a fixed price and a target launch date before any code is written.

01

Discovery & Scoping

A focused working session to map goals, audiences, content model, and integrations. The output is a written scope, a fixed price, and a target launch date.

  • Project brief & scope
  • Fixed-price estimate
  • Architecture sketch
  • Launch timeline
02

Design & Data Model

Page-level wireframes and high-fidelity mockups, paired with the Postgres schema and CMS collections. UI and data are designed together so neither bottlenecks the other.

  • Page designs
  • Component system
  • Postgres schema
  • CMS collection model
03

Build & Iterate

Built in Next.js or React Router v7, deployed continuously to a preview URL from day one. You see progress weekly and can request changes before anything ships.

  • Weekly preview deploys
  • Loom walkthroughs
  • Issue tracker access
  • Iterative reviews
04

Launch & Hand-Off

Production deploy, DNS cutover, analytics, error tracking, and a recorded walkthrough of the codebase and CMS. You own the repo, the database, and every credential.

  • Production deploy
  • Owner-controlled hosting
  • Codebase walkthrough
  • Editor training
05

Iterate or Hand the Keys

A short post-launch warranty window for fixes. After that, you can hire me on a retainer for ongoing work or take the codebase to any React engineer — it is a clean repo, not a black box.

  • 30-day warranty
  • Optional retainer
  • Documented codebase
  • Zero vendor lock-in

FAQ

Custom Web Development Questions

Answers to the most common questions about scope, pricing, timeline, and how a custom React build compares to off-the-shelf platforms.

Custom web development means the site or application is written in real code — in this case React on top of Next.js or React Router v7 — without relying on a page-builder or a marketplace of third-party plugins. WordPress and Shopify are excellent for off-the-shelf use cases, but they constrain UX, performance, and data modeling. A custom build trades plug-and-play convenience for full control over how every page renders, how data is stored, and how your team edits content.
Focusing the stack is the difference between a deeply experienced engineer and a generalist. I have shipped React in production for years, and Next.js plus React Router v7 cover essentially every shape of marketing site, web app, and admin panel I am asked to build. Staying inside one ecosystem means faster builds, fewer bugs, and a codebase any other React developer can step into later.
Yes. Postgres is the default — hosted on Neon, Supabase, RDS, or your provider of choice. I design the schema up front, run versioned migrations, and wire everything into the React app with type-safe queries. Authentication, multi-tenant isolation, and complex relational models are all part of the standard offering.
Yes. The custom CMS is built on the same React stack as the front end, so editors and developers share one codebase. That can mean a Payload CMS or Sanity setup, or a fully bespoke admin with collections, drafts, roles, and audit logs. The result is an admin that mirrors your actual editing workflow instead of forcing your workflow into a template.
Most marketing sites land between $8,000 and $25,000. Web applications with custom CMS and Postgres typically run $20,000–$60,000+ depending on scope and integrations. The interactive estimator on this page produces a real, defensible range from a few sliders. Every engagement starts with a written, fixed-price scope before any code is written.
Marketing sites usually ship in 4–8 weeks from kickoff. Web applications with a custom CMS land in 8–14 weeks. Rush timelines are available with a 25% uplift when the calendar allows it. Solo, US-based execution is what makes the schedule possible — there is no hand-off lag between strategy, design, and engineering.
Yes — I am headquartered in Salt Lake City, Utah, and I work with clients across the entire United States. Local Utah businesses get the option of in-person kickoffs, on-site working sessions, and quarterly strategy meetings; out-of-state clients run the same engagement remotely over Zoom and Loom. Either way, every line of code is written in the US — there is no offshore sub-contracting at any point.
Both options are available, and most clients choose to bundle. Technical SEO — JSON-LD schema, XML sitemaps, canonicals, Core Web Vitals, semantic HTML, image optimization, and editor-controlled meta — is included in every custom build by default, because RedSEO is a working SEO agency first. For ongoing content SEO, link building, and rankings work, RedSEO runs full-service Utah SEO retainers from $1,500/month. Bundling the build and the retainer means one team owns both the code and the rankings, which is rare for a custom development engagement.
No. You own the repository, the hosting account, the database, and every credential. After the 30-day warranty window, you can keep me on retainer for ongoing work or hand the codebase to any React engineer. The whole point of staying in a focused, conventional stack is that you are not stuck with me to keep it alive.
Yes. Authenticated portals with roles, billing, file workflows, and per-tenant data isolation are a regular part of the work. The Postgres schema and React routing structure are designed for that case from the start — not bolted on later.
