Web Development

SaaS products and web apps that ship fast and scale further

We build full-stack web applications using Next.js 15, TypeScript, and modern tooling — from zero-to-launch MVPs to complex multi-tenant SaaS platforms. Performance, SEO, and code quality are non-negotiable.

What's Included

  • SaaS platforms — auth, billing, multi-tenancy, dashboards
  • Next.js 15 with App Router, Server Components, and edge rendering
  • AI-powered features built in from day one
  • E-commerce with optimised checkout and conversion flows
  • Core Web Vitals scores that actually rank on Google
  • CMS-powered content with Sanity or Contentful

MVPs That Don't Need Rebuilding

Most agencies build fast or build well. We do both — because a product that works today but needs a rewrite in 6 months is not a success. Our architecture decisions are made for where you're going, not just where you are.

What We Build

From subscription SaaS platforms to high-traffic marketing sites, from AI-powered internal tools to e-commerce storefronts — we've shipped products across every category. If it runs in a browser, we've probably built it.

Performance Is a Feature

We obsess over Core Web Vitals. Every site we ship targets LCP under 1.5s, CLS under 0.05, and INP under 100ms — because slow websites lose customers, rankings, and revenue.

Frequently Asked Questions

How long does it take to build a web app or SaaS MVP?

A focused MVP typically ships in 4–8 weeks, while a full multi-tenant SaaS platform runs 8–16 weeks depending on scope. We work in weekly milestones so you see working software early and often, rather than waiting months for a big reveal.

Do you use Next.js, and why?

Yes. We build on Next.js with the App Router, Server Components, and edge rendering because it delivers strong Core Web Vitals, first-class SEO, and a single codebase for frontend and backend. That combination is why our sites rank well and load fast out of the box.

Can you take over an existing or half-finished codebase?

Yes. We regularly audit, refactor, and extend existing React and Next.js codebases. We start with a short technical review, document the risks, and then improve the code incrementally without a risky full rewrite.

How much does custom web development cost?

Most engagements are scoped as fixed-milestone projects or a monthly retainer. Pricing depends on complexity, but we give a clear estimate after a free discovery call so there are no surprises.
