I BUILD
APPS, WEBSITES
& IDEAS.
Hi, I'm Subhan Haider. A high school student turning curiosity into functional Android applications, clean web experiences, and open-source experiments.
I LEARN BEST
BY BUILDING REAL THINGS.
Instead of getting stuck in endless tutorial loops, I learn by building actual applications. Every project is an opportunity to explore software architecture, database design, animations, and real-world problem solving.
Android Native
Crafting native Android experiences with Kotlin, Jetpack Compose, Room, and modern MVVM patterns.
Modern Web
Building responsive, high-performance web applications using React, Next.js, and TypeScript.
Offline & Private
Designing offline-first systems where user data stays private, encrypted, and accessible at lightspeed.
Open Source
Sharing templates, modules, and code publicly on GitHub to support and collaborate with the developer community.
SELECTED WORK.
BUILT FOR
THE ANDROID OS.
Android development is where my passion for software engineering truly began. I focus on creating fluid, native applications leveraging the full power of modern Android toolchains.
Declarative UI with Jetpack Compose
100% reactive state management, seamless dark/light Material 3 theming, and hardware-accelerated animations.
Clean Architecture & MVVM
Separation of concerns across UI layer, domain use cases, and repository data sources with Kotlin Flows.
Offline-First Room SQLite Database
Fast, secure, on-device data persistence ensuring zero network latency and complete user privacy.
class FinanceViewModel(
private val repository: FinanceRepository
) : ViewModel() {
// Reactive UI state stream
val uiState: StateFlow<FinanceUiState> =
repository.observeTransactions()
.map { list -> FinanceUiState.Success(list) }
.stateIn(viewModelScope, SharingStarted.WhileSubscribed(5000), Loading)
fun addTransaction(entry: Transaction) =
viewModelScope.launch(Dispatchers.IO) {
repository.insert(entry)
}
}
TOOLS I USE
TO BRING IDEAS TO LIFE.
A versatile stack covering native mobile programming, modern web frameworks, databases, and design.
FEATURED EXTENSIONS.
Cross-browser tools and apps published on the Chrome Web Store, Edge Add-ons, Firefox AMO, and Microsoft Store.
LIVE GITHUB ACTIVITY.
THE JOURNEY SO FAR.
From early curiosity in high school to building full-fledged mobile and web products.
LET'S BUILD
SOMETHING IMPACTFUL.
