Next.js development · Sydney
Web applications built to be fast, indexable and ready to scale.
I build a free working concept first, so you can see and click through your new application before you commit. If you like where it's going, you get a fixed price and a fixed timeline. The timeline holds as long as I get your feedback within 48 hours.


















Next.js combines React with server-side rendering, static site generation and edge deployment, which makes it one of the most flexible frameworks for building web applications. It suits startups and SaaS businesses that need an application built for performance, scalability and a good developer experience.
I'm Aaron Knight, a Sydney-based developer with over 13 years of experience building custom web applications for businesses at every stage of growth. I design and build Next.js applications that are fast, scalable and structured to grow with your product, from MVP through to enterprise scale.
Next.js is built by Vercel on top of React, and it's one of the most widely used React frameworks. Its hybrid rendering model lets pages be server-rendered, statically generated or client-rendered where that makes sense, so applications load quickly whatever the content type.
Unlike a standard React single-page application, Next.js renders content on the server or at build time, which makes it far easier for search engines to index. It deploys easily to edge networks, and it includes TypeScript support, React Server Components and the App Router.
From MVP builds to ongoing development, every application is built on clean architecture you own outright.
Every application starts with a clear understanding of your product requirements, your users and your growth plans. I design and develop a custom Next.js application with clean architecture, well-structured code and a frontend that performs at scale, whether you're building an MVP or extending an existing product.
For businesses with an existing backend or API layer, I build high-performance Next.js frontends that connect to your data sources. I choose the right rendering strategy for each page, whether that's server-side rendering, static generation or incremental static regeneration, and the right state management approach for more complex interfaces.
Next.js pairs well with headless CMS platforms, so your team can manage content without touching code while the frontend keeps the performance of a statically generated site. I integrate Next.js with Contentful, Sanity, Strapi, Prismic and others, including content models and components that suit your team's workflow.
Modern web applications are built on APIs. I design and build Next.js API routes and integrate external services such as authentication providers, payment gateways, CRM platforms, analytics tools and external data sources, with server-side logic and security applied cleanly.
Next.js is fast by default, but only when it's used correctly. I audit existing applications for unnecessary client-side rendering, unoptimised images, weak caching, inefficient data fetching and font and image gaps, then implement improvements that move Core Web Vitals scores into the green.
I implement server-side rendering and static generation strategies so your application's content is fully indexable, with structured metadata, Open Graph tags, schema markup and sitemap generation handled correctly from the start.
For SaaS businesses building or scaling their core product, I offer end-to-end Next.js development, covering user authentication, subscription management, multi-tenancy architecture, dashboards and ongoing feature development, working closely with founders and product teams to avoid accumulating technical debt.
I build Next.js MVPs that launch quickly, are easy to iterate on and sit on a foundation that won't need to be thrown away once the product is validated. The goal is always a codebase you can grow.
I design and build AI integrations that add genuine value to your product, including LLM-powered features, recommendation engines and automated workflows connected to external AI services.
I offer ongoing development retainers for startups and SaaS businesses that need a reliable technical partner for feature development, bug fixes, performance monitoring and infrastructure improvements, without the overhead of a full-time hire.
The right answer depends on what you are building. Many businesses use both: a WordPress site for content and marketing, and a Next.js application for the core product or customer portal.
Authentication, dynamic data or complex interactivity.
Building or scaling a product.
Maximum performance and control over the architecture.
Your team will maintain the codebase after launch.
I can advise on the right architecture for your situation.

You get a developer who is accountable for the whole build, not a handoff between teams:
Building Next.js applications well takes a clear understanding of rendering strategies, caching, API design, state management and performance. I bring 13+ years of development experience to every project.
I understand the constraints of early-stage and growth-stage companies: speed to market, managing technical debt and building on foundations that scale.
You deal with me directly, backed by a small, hands-on team. Architecture decisions, feature development and technical direction all run through me.
Rendering strategies are chosen with indexability in mind, metadata is implemented correctly and performance is optimised for Core Web Vitals.
I offer retainer-based development for startups and SaaS businesses that need a technical partner beyond the initial build.
AI features work best when they are designed into the application from the start.
LLM-powered features, recommendation engines, personalisation and automated content workflows, built into the product itself.
Automation layers that connect your product to external AI services and your broader business systems.
Not sure where AI fits in your product? I help you identify where it adds real value before any development begins.
AI features perform best on a fast, well-structured application with clean data and sensible architecture, which is how I build.
Each stage is agreed before the next one begins.
Understanding your product, your users, your technical constraints and your growth plans before any architecture decisions are made.
Defining the application structure, rendering strategy, API design, CMS selection, hosting and third-party integrations before development begins.
Creating component designs and UI systems that reflect your brand and prioritise usability across devices.
Building the application with clean, well-structured Next.js code, componentised, documented and managed through Git-based workflows.
End-to-end testing across browsers and devices, Core Web Vitals benchmarking and SEO auditing before launch.
Deploying to your chosen hosting environment with analytics, error monitoring and performance tracking in place from day one.
Feature development, bug fixes, performance improvements and infrastructure updates on a retainer basis after launch.
Next.js websites and web applications are scoped individually after a quick call. Website builds sit within my usual $4,000 to $25,000 range, and ongoing development, feature work and fixes are billed at $120 per hour.
You get a fixed price once the scope is clear.
Can't see your question?
Next.js is a React-based framework that adds server-side rendering, static site generation and performance improvements on top of standard React. For web applications it offers better SEO capability, faster initial load times and a more scalable architecture than a client-side React app.
WordPress is a content management system designed for websites that non-technical users manage. Next.js is a framework for building web applications, SaaS products, customer portals and dynamic platforms. The right choice depends on what you're building.
Yes. Next.js works well for headless ecommerce, where the storefront is built in Next.js and connected to a backend such as Shopify, WooCommerce or a custom API. It needs more development investment and technical maintenance than a standard theme.
An MVP typically takes six to ten weeks from briefing to launch. Applications with authentication, subscriptions, complex data models or significant integrations take longer. The timeline is defined during architecture planning and agreed before development begins.
Yes. I work with existing applications as well as new builds, for performance optimisation, feature development, technical audits and ongoing support. Get in touch with a description of what you're working with and I'll let you know what's involved.
Vercel is the natural home for Next.js, as it's built by the same team. For applications with specific infrastructure needs or existing cloud relationships, I also deploy to AWS, Google Cloud and other environments, and I'll recommend the setup that fits your requirements and budget.
Yes. I build LLM integrations, AI-driven recommendations, automated content workflows and chatbot interfaces into Next.js applications. If you have a specific feature in mind, get in touch and I'll let you know what's involved.
You don't pay the final balance until you're happy with it. The project starts with a 50% deposit, then I keep working until you're happy before the balance is due. Every project includes revisions throughout the process, and I won't consider the job done until we've arrived at something we're both proud of.
If you're looking for an experienced Next.js developer in Sydney, I'd like to hear about your project. I'll give you a straight answer on what's involved, what it will cost and what's realistic to achieve.
Call Monday to Friday, 9 to 5 on (02) 8317 3526, or send through an enquiry and I'll get back to you promptly.
