Base44 app development

Full-stack Base44 apps, built properly.

I've shipped 20+ apps for real clients, most of them on Base44. Logins, dashboards, payments, email, the lot. Built with access rules from day one, so it doesn't fall over the first time a real user turns up.

Who it's for

Sound familiar?

I build full-stack apps on Base44: data, access rules, backend, frontend and everything in between. I've shipped 20+ of them for real clients.

Tell me about it
  • You have an idea and want it built right the first time.
  • You've got a half-built Base44 app that's stuck.
  • You've been going round in circles with the builder AI.
  • You need an internal tool that real people will use every day.
What you get

What you actually get.

  • 01

    A data model that makes sense

    One entity per kind of thing, the right fields and the right relationships. Get this wrong and everything after it hurts.

  • 02

    Access rules from day one

    Row-level security on every entity and a security scan before launch. Not a clean-up job at the end.

  • 03

    The whole stack

    Frontend, backend functions, integrations and workflows, all in one app that I understand end to end.

  • 04

    Payments and email if you need them

    Stripe payments and subscriptions and Resend email are running in production on apps I've built.

  • 05

    A handover you can build on

    A walkthrough and notes, so you know what you own and how it fits together.

How it goes

How it goes.

Five steps, in this order. You see progress at every one of them.

How I work on every project

  1. Step 01

    Questions

    What's the real problem, who's it for and what does done look like? I ask a lot before I build anything.

  2. Step 02

    Plan the data

    Entities, roles and access rules first, then the screens that sit on top.

  3. Step 03

    Build in the open

    You see progress as it happens, with live links along the way.

  4. Step 04

    Test and ship

    Real devices, a security scan and the flows your users will take. Then it goes live.

  5. Step 05

    Hand over

    A walkthrough and notes so you're never stuck waiting on me.

FAQ

Questions people ask.

Something else on your mind? Ask me. I answer everything myself.

Ask a question

Yes. A lot of my work starts that way. I'll go through what's there first, tell you what's solid and what isn't, and then we decide whether to fix it or rebuild parts of it.
