05 · WHO BUILDS IT

Hi — I'm Eldar.

I've shipped 8 iOS apps to the App Store solo, won the Google DeepMind hackathon twice in a row, and built the AI agent infrastructure that runs my company's daily ops.

Now I'm taking on 1 founder at this rate as a direct client. No juniors. No agency middlemen. Every line goes through me.

If you're tired of vibe-coded MVPs that get rejected and $80K agency quotes for things I'd ship in four weeks — let's build the real thing.

Frequently asked.

Me — Eldar Agayev. Every line. Computer Science degree + Business from The University of Warwick (and Warwick Business School). 2× Google DeepMind hackathon winner. 8 iOS apps shipped solo. No juniors, no outsourcing.

Average request: 48–72hr. Full app build (zero to App Store): 4–6 weeks. Vibe-code rescue: 2–4 weeks. The only delay we can't control is Apple's review queue.

Mobile dev never ends. Bug fixes, feature iterations, A/B tests, App Store rejections, iOS migrations. Subscription means we're with you across all of that — pay only while you need us.

Add unlimited to your queue. We work on one at a time — you choose. Big requests get broken into smaller deliverables (design → core flow → backend → polish → submission).

Yes. First month builds your MVP. Subsequent months iterate, add features, fix bugs, expand to Android. Most clients keep the subscription for 3–6 months.

That's the Vibe-Code Rescue track. Send your repo, App Store Connect access, and what's broken. We rebuild it properly. Most rescues: 2–4 weeks.

Included. Native Kotlin or cross-platform (Flutter / React Native). Most clients start iOS-only and add Android in month 2 or 3.

Included. Wireframes, polished SwiftUI, Liquid Glass icons, App Store screenshots. If you have your own designs, we follow them.

Included. Supabase, Firebase, AWS, custom backends. You only pay infra costs your app generates (your own AWS bill, Supabase paid tier, etc.).

Everything. Day one. Private GitHub repo, full IP. We build for you, not over you.

Zero meetings. Dashboard (Linear or Trello, your choice) + shared Slack/Discord. Async, fast, in writing.

Anytime. Pause for a month, cancel forever, come back later. Current month non-refundable. No contracts, no penalties.

We fix it. Free. Guideline 2.5.2, 4.3, 5.1.1, anything else.

The growth platform I built for app founders — keyword research, competitor analysis, ASO scoring. Normally a separate subscription. Free with madOS Build.

I do every line. To keep quality high and turnaround under 72hr, I take on a small number at a time. The next subscription will be at the standard $5,999/mo rate.

London, UK. Working with founders globally. Async-first means timezone doesn't matter.

No refunds — but cancel anytime, and you keep all the code.
