Aatman (AJ) Jain · Belfast

I build apps that look designed, not generated.

I'm Aatman (AJ) Jain, a 15-year-old developer and Base44 Partner in Belfast. 20+ apps shipped for real clients. One Best Build, won with my dad.

Stuff I build with

Stuff I build with: Base44, Claude, OpenAI, Codex, Cursor, Higgsfield, Stripe, Resend, React, Tailwind CSS, Vite, Deno, GitHub, Tauri, Rust, Python, JavaScript.

Selected work

Built for problems I ran into myself.

No client showcases here. Just my own projects: a Best Build winner, two free guides, a sweepstake app and an archive for the Base44 community.

Case study 02Guide2026

A free, friendly explainer for Base44 Superagents. I built it because the same questions kept coming up in the Discord, and I checked every claim against Base44's live docs.

  • Every claim checked against Base44's live docs
  • A mascot called Nova
  • Covers the six parts, use cases and a prompt library

A sweepstake app for the 2026 World Cup. It dealt all 48 teams out with a draw anyone could verify, tracked every fixture and never touched a penny. Sketched on paper, shipped in 8 hours.

AJ is one of those people who makes every project better. … His UI work is some of the best I've seen, and he's prompt, helpful, and genuinely invested in getting things right.

AJ is honestly one of the most impressive young builders I have seen in the Base44 community. … There are days where it feels like AJ is answering half the community himself.

My story

It started during COVID. It hasn't stopped.

Lots of building, plenty of breaking, and one competition I entered with my dad.

Read the whole story
  1. During COVID

    Started programming

    I wrote my first real lines of code during COVID. I haven't really stopped since.

  2. The years after

    Picked up six languages

    Python, JavaScript, HTML, CSS, R and C#. Mostly by building small things and breaking them.

  3. 2025

    Found Base44

    My first real app went live the same week I signed up. That was when it clicked: the bottleneck was the tooling, not the skill.

  4. 2025

    First paying client

    Freelance work, built in public. Then ten apps. Then twenty.

  5. 2025

    Got stuck into the Discord

    The Base44 Discord became where I learned in public and helped people with their apps. It taught me which questions uncover the real problem.

  6. 2025

    Became a Base44 Partner

    Since then I've been helping people build, fix and ship their Base44 apps. 5.0 from 9 reviews so far.

    Won Best Build, with my dad

    My dad and I built The Gridiron Guide for Base44's Big Game App competition. It won Best Build.

  8. Along the way

    Highlighted by Base44

    Base44 highlighted my work. I'll take it.

  9. Now

    Still building, still learning

    20+ apps shipped for clients and 70 Office Hours sessions archived. Now I'm building websites and tools for Base44 users, growing on X and learning Rust.

    What I'm up to now
  10. That's the short version.

    The long one has more bugs in it. Mostly mine.

Reviews

I'll let the reviews do the bragging.

Copied exactly as written, typos and all. The long ones are trimmed, never reworded.

  • AJ has been one of my favourite devs to work with. … He doesn't put you in mind just as a client, he puts your users in mind…

    MeganBase44 review
  • AJ is the real deal, from Front End UI, Pen Testing, Complex API integrations. AJ really knows what he’s doing. 100% recommend working with AJ on your next project!

    Roenic NatarelliBase44 review
  • Found AJ on Discord - was super helpful right from the get go! … Doesn't look to sell me his services unless I need them and was ready to help for free because it was a 2 minute fix.

    holly.hates.mondays (Shadling)Base44 review
  • He not only helped resolve my issues but he has a great way of thinking through the process. … He came up with some concepts that I hadn't thought of on my own.

    Mitch Fields (NurturInk.com)Base44 review
  • AJ is one of the youngest and brightest minds around Base44! … If you get the opportunity to work with him consider yourself lucky!
