02 · WHAT WE DO

Every layer of your app.

Six layers between an idea and revenue. We own all of them, so you don’t end up coordinating five vendors.

01DESIGN

Sketch to App Store-grade UI.

Wireframes, brand, polish, screenshots. Looks like Apple shipped it.

Figma
SwiftUI
Liquid Glass

02iOS · ANDROID

Native code, both platforms.

Production apps, not vibe-coded prototypes. Liquid Glass on iOS, Material on Android.

Swift 6
iOS 26
Kotlin
React Native

03BACKEND

You don’t touch a server.

Auth, payments, sync, storage, push. Production-ready from day one.

Supabase
Firebase
Stripe
RevenueCat

04AI

Built into the product. Not bolted on.

Agent workflows that actually work. Streaming, RAG, tool-use, on-device.

GPT
Claude
Gemini
CoreML

05LAUNCH

App Store + Play Store. Submitted.

Connect setup, TestFlight, screenshots, keywords, ASO. Apple rejection? Free fix.

App Store Connect
TestFlight
ASO via madOS

06GROW

Why aren’t they converting?

Analytics that answer that. Push, paywall, retention, A/B — iterated weekly.

+ ALSO IN THE BOXCompanion web (Next.js · Tailwind · Vercel). Infrastructure (Supabase · Firebase · AWS) — your bills. Workflow tools (Linear or Trello, your choice). Slack channel with the founder.

03 · WHO IT'S FOR

Sound familiar?

Four reasons most founders end up here. See if any sound like you.

01PROFILE

You shipped with AI. Now it’s stuck.

Cursor, Lovable, Bolt got you live. But you don’t really know what the AI built — is it secure? Will it work on all devices? Can users “cheat” the paywall? Nothing’s instrumented, so you can’t see why downloads aren’t converting. And once you do get early success, you can’t polish, fix the design, or scale without diluting ownership or paying an agency hundreds of thousands.

You got an $80K quote. You walked.

An agency quoted you four months and a year’s runway for an MVP. Same scope, lower price, faster turnaround. By one person, not a billable team.

03PROFILE

You have the idea. You don’t have the team.

You’re not a developer. You’re not learning Swift. You want one senior person to take it from idea to App Store and beyond — design, build, ship, grow.

04PROFILE

You have an idea. You want it shipped this month.

Not building a 5-year company yet. You just want to test the idea, get to the App Store, and see if it gets traction. No subscription, no commitment — a working app in your hands by next week.

05 · WORK

Eight.
Live on the App Store.

Not concepts. Not vibe-coded MVPs. Eight production iOS apps live on the App Store — built, designed, and shipped by one person. Same person who'll be writing yours.

iOS apps shipped

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 a time 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.

choosing madOS over a full-time hire

OPTION A

Traditional hire

Senior dev · in-house

Monthly cost: $18,125/mo
Annual cost: $217,500/yr
Upfront costs: $18,000

Flat monthly · pause anytime

Monthly cost: $3,999/mo

*In-house figure assumes a 1.45× loaded cost factor on base salary (US senior software engineer, 2026 — covers benefits, payroll tax, equity, equipment, software seats) plus $18K upfront for recruiter fees and onboarding ramp. madOS is flat monthly, no upfront, pause or cancel anytime.

08 · CLIENT

“He built our app in 3 weeks. The agency quoted 12 weeks for $40K. He charged $6K and the result is better.”

10 · FAQ

Frequently asked.

Anything else — ask in the shared channel after you subscribe.

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.

Rapid MVP is one-shot: one app, one week, $3,000, and we're done. Founder Plan is ongoing: unlimited builds, iterations, growth support, $3,999/mo. Most founders start with Rapid MVP, then switch to Founder Plan once it's working.

Then Rapid MVP isn't right — start with Founder Plan. Or book the intro call and I'll tell you straight.

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.
