Web Development Miami — Custom Sites & Web Apps
Miami.
Beyond websites. JAAR Design builds custom web applications, e-commerce stores, headless CMS architectures, and integration-heavy platforms for Miami businesses.
Miami web development engineered for what comes after launch.
Web development in Miami has plenty of options if you need a brochure site. The talent gets thin fast when you need a custom dashboard, a multi-tenant SaaS, an integration with a legacy ERP, or a headless storefront that has to load in under a second on a phone in poor signal.
JAAR Design fills that gap. Our developers ship in modern stacks — Astro, Next.js, React, Node, TypeScript, WordPress (when it makes sense), Shopify Hydrogen, and headless CMSes like Sanity, Contentful, and Storyblok. Every project gets architecture review, code review, and a deployment pipeline you can trust.
If your existing developer disappeared, your CMS is held together with plugins, or your "custom" platform is actually a buggy template — we have probably untangled something worse last quarter. Most rescues start with a paid technical audit so we can give you an honest read on what to fix vs. rebuild.

Why JAAR Design
Engineering Miami businesses can rely on
JAAR Design pairs engineers with strategists from day one. The result is code that solves the actual business problem — not a beautiful technical solution to the wrong question.
We own the work end to end. Architecture, build, deployment, monitoring, and ongoing maintenance. When something breaks at 11pm on a Tuesday, we are the team that picks up.
FAQ
Frequently asked questions
What tech stacks do you use?
Most often: Astro or Next.js for marketing sites, React/TypeScript for web apps, Node + PostgreSQL on the backend, and headless CMSes like Sanity or Contentful. We use WordPress when content workflows demand it. We do not push a stack — we recommend based on your team and goals.
Can you take over an existing project?
Yes. We regularly inherit codebases, audit them, and either continue development or rebuild incrementally. We always start with a paid audit so you know what you have before committing to next steps.
Do you build mobile apps too?
Yes — see our app development page. We build native iOS, native Android, and cross-platform via React Native and Flutter.
How do you handle ongoing maintenance?
Monthly retainers for security updates, dependency upgrades, bug fixes, performance monitoring, and feature additions. Most clients move into a retainer post-launch.
Do you have references in Miami?
Yes. Live sites in our portfolio include real estate, hospital, healthcare staffing, legal/IP, and personal brand projects. Happy to introduce you to past clients during the discovery process.
