This service covers a focused, single-feature app or screen flow: the kind of thing you need for an MVP demo, a portfolio piece, or testing a concept before committing to a full build.
What you get:
Native Android + iOS app from one Kotlin Multiplatform + Compose Multiplatform codebase
Clean Architecture (MVI pattern), properly separated UI/logic/data layers
Basic Material 3 theming
Source code + setup instructions, fully documented
A note on AI integration: I also build AI-powered features — chat assistants, smart recommendations, LLM-powered backends — when a project calls for it. This base service is scoped to a single feature without AI; if you want AI built in, message me before ordering and we'll figure out the right scope and price together.
Who this is for: founders testing an idea, anyone who wants to see a real working screen before committing to a bigger build, or a first project together so you can see how I work.
Message me before ordering if you're not sure your idea fits a single feature — I'd rather scope it right than have you order something too small for what you need.

If you want a mobile app that feels native on both Android and iOS — without paying for two separate codebases that slowly drift apart — Kotlin Multiplatform with Compose Multiplatform is the right way to build it in 2026. I build apps this way exclusively, because it means one team (me), one codebase, and one set of bugs to fix instead of two. Why Kotlin Multiplatform + Compose Multiplatform Most "cross-platform" tools either wrap a website in an app shell (slow, feels wrong) or force you to maintain two native apps in parallel (expensive, inconsistent). Kotlin Multiplatform compiles your business logic to real native code on both platforms, and Compose Multiplatform renders real native UI from the same codebase. The result: a genuinely native app, built once, that behaves consistently everywhere. Where AI fits in A lot of mobile devs stop at "the app works." I go further when you need it: AI-powered chat assistants inside your app, smart recommendations, automated content generation, or a backend agent that handles conversations with your users in real time. I've personally built a working AI system — a Flask + Socket.IO backend that runs an LLM-powered agent through tool-calling, holds multi-turn conversations, and turns natural language into structured data the app can use. If your app idea involves "smart" anything — a chatbot, a recommendation engine, an AI assistant feature — I can design and wire that in, not just bolt on an API call. My approach Understand the app, not just the feature list. I ask about your users and what they're actually trying to do before writing code, so the architecture fits the real use case instead of being generic. Build with Clean Architecture + MVI. This keeps your codebase organized from day one — UI, business logic, and data are cleanly separated, so adding features later doesn't mean rewriting old ones. Use the right data layer for your needs. Room for fully offline-first apps, Firebase or Supabase if you want real-time sync and auth out of the box, or a custom REST/Ktor integration if you already have a backend. Ship something you can actually test. You get working builds, not just code — I want you opening the app on your own phone, not just reading source files. Document what I build. Setup instructions, architecture notes, and comments where logic isn't obvious — so you're not stuck if you bring in another developer later, or come back to me in six months. What you get, every project: Native Android + iOS apps from one Kotlin Multiplatform + Compose Multiplatform codebase Clean Architecture with MVI pattern, properly separated layers Koin for dependency injection, Ktor for networking Room database, or Firebase/Supabase integration if you need cloud backend Material 3 theming — light/dark mode, responsive layouts across screen sizes Clean, commented, maintainable code with setup documentation Optional AI integration: chat assistants, smart suggestions, or LLM-powered backend logic, scoped to your package Who this is for: Founders who need an MVP they can actually demo to users or investors Small businesses who want one app that works well on both platforms instead of two half-finished ones Anyone who wants an "AI-powered" app feature but isn't sure how to scope or build it technically A note on where I'm at: I'm building my track record here on ComeUp, which means my rates right now are lower than they'll be once I have a review history — you're getting the same architecture decisions and code quality I'd charge more for later, while I earn my first reviews. I treat every project like it's the one that gets shown to the next client, because it is. Message me before ordering if your idea doesn't fit neatly into a package below — I'd rather scope it right than have you order the wrong tier.
