Web applications & digital growth

Web applications, made to work.

Direct access. Practical progress. A partner genuinely invested in your success.

I design and build refined digital products that help businesses attract more people, convert more opportunities, and keep improving after launch.

A boutique consultancy led by Andrew Cates — I take on a limited number of clients at a time, so every project gets my full attention.

Create · Improve · Care · Grow

One dedicated partner for the whole life of your product.

From the first build through ongoing improvement, one accountable partner keeps your product healthy and helps it earn more attention and more business.

Create

Design & build

The core project engagement: turning an idea into a production-grade web application through a high-iteration design process.

Improve

Optimize what exists

Project-based improvements to lift conversion, performance, accessibility, and reach after launch.

Care

Ongoing partnership

The monthly recurring relationship — part maintenance, part online coach for your digital presence.

Grow

Traffic & lead generation

Higher-value advisory that puts more of the right eyes on your pages and turns them into customers.

Your online growth coach

The point isn’t a website. It’s more business.

Once your site is live, the real work begins: getting more eyes on your pages, and turning those visits into sales, bookings, and leads. I track it, explain it, and keep improving it alongside you.

See how it works

More eyes on your pages

I monitor traffic and search visibility, spot dips before they hurt, and lay out exactly how to bring more of the right visitors in.

Lead generation, built in

Landing-page campaigns, funnels, and follow-up automation that turn attention into qualified leads — a differentiator most studios skip.

Optimized, continuously

Ongoing performance and conversion work so your site loads faster and turns more visitors into customers over time.

Advice you can act on

Plain-language monthly reporting on what changed, why it matters, and the one thing worth doing next.

Capabilities & add-ons

Add what your business needs, when it needs it.

Every build starts with a beautiful, reliable core. These are the capabilities I layer on top — booking, payments, lead capture, AI, and more — each proven across real client work and priced per project or bundled into a plan.

Explore all capabilities

Online Booking & Scheduling

Turn interest into a booked appointment.

Payments & Subscriptions

Get paid — one-off, packs, or recurring.

Edit your own site — no developer required.

Email, SMS & Notifications

Keep it healthy. Keep it improving.

Once your application is live, a monthly plan keeps it healthy, improving, and growing. Start light with monitoring, or bring on a hands-on partner.

A personal note

You’ll always know exactly who’s responsible.

When you hire me, I stay responsible — from the first conversation through the code that ships and the improvements that follow. You get one accountable partner who understands the work and keeps its context.

If that’s the kind of partner you’ve been looking for, I’d love to hear what you’re building.
