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. 01 / What it is ## Why Next.js? 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. 02 / Services ## Next.js Development Services From MVP builds to ongoing development, every application is built on clean architecture you own outright. 01 ### Custom Next.js Application Development 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. 02 ### React & Next.js Frontend Development 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. 03 ### Headless CMS Integration 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. 04 ### API Development & Third-Party Integrations 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. 05 ### Next.js Performance Optimisation 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. 06 ### Next.js SEO Implementation 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. 07 ### SaaS Application Development 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. 08 ### MVP Development 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. 09 ### AI Integration for Web Applications 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. [AI development & integration →](https://aaronknight.com.au/sydney-ai-agency/)10 ### Ongoing Development & Support 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. 03 / Which one? ## Next.js or WordPress? 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. ### Choose Next.js if ### You are building an application Authentication, dynamic data or complex interactivity. ### You are a SaaS business Building or scaling a product. ### You need frontend control Maximum performance and control over the architecture. ### You have developers Your team will maintain the codebase after launch. ### Choose WordPress if - **You need a content-managed website** Non-technical team members update the content. - **SEO and lead generation are the priority** Content marketing and enquiries drive the business. - **You have no development team** Someone needs to manage the site without a developer. - **You want a cost-effective launch** A site that launches and is managed quickly. I can advise on the right architecture for your situation. 04 / Proof ## Results From Recent Work ### Awards, Nominations & Accolades CSS Design Awards winner. 4.9 stars from 33 Google reviews.

Talk it through with me directly, Monday to Friday, 9 to 5.[Call me on 02 8317 3526 →](tel:+61283173526)What is Next.js and why should I use it?+ 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. How is Next.js different from WordPress?+ 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. Can Next.js be used for ecommerce?+ 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. How long does a Next.js project take?+ 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. Do you work with existing Next.js codebases?+ 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. What hosting do you recommend for Next.js?+ 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. Can you help with AI features in my Next.js app?+ 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. Our guarantee ## Web Design Happiness Guarantee 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. - **Fixed price.** Agreed once you've seen and approved the concept. - **Fixed timeline.** It holds as long as feedback comes back within 48 hours. - **30 days of support.** Included after launch as standard. - **It's yours.** Full ownership of the site, accounts, content and code.
