Next.js and Sanity Development Retainer.

Guaranteed availability to an experienced Next.js and Sanity developer.

Growth comes from momentum. Your website is your most important marketing asset, the one place you fully control, working around the clock to bring in business.

Competitors move fast and customer expectations don't stand still. Falling behind on your website means falling behind in the market.

That's the gap this retainer fills.

Each month, a limited number of spots go to businesses that want a developer embedded with their marketing team.

On retainer, I build new landing pages for upcoming campaigns, roll out features as your product evolves, fix bugs before they cost you conversions, and make ongoing tweaks based on what the data tells us.

No waiting on a quote, no re-briefing a new developer every time. Just steady, dedicated support that keeps pace with your marketing calendar.

Think of it as having an experienced developer in your corner, without the overhead of hiring one.

Someone who already knows your codebase, what your business is trying to achieve, and is genuinely invested in the outcomes — not just getting paid and moving on to the next client.

Next.js and Sanity expertise you can rely on

Deep specialisation in one stack

I focus exclusively on Next.js and Sanity. That means every hour of your retainer goes toward solving problems, not learning a new framework on the job.

Responsive when it matters most

Urgent requests are handled the same day wherever possible. There's no onboarding delay and no need to bring anyone up to speed.

An extension of your team

Over time, I gain the same context a permanent hire would have, without the overhead of one. That means decisions get made faster and with more confidence.

Accountability in every decision

I stand behind the work I deliver. That means avoiding shortcuts, patterns that don't scale, and quick fixes that cause issues down the line.
