Industrial-Grade Mobile Infrastructure & Zero-Copy Vision Engines

Kotlin Multiplatform • Native Android / iOS • Flutter • High-Throughput Media Pipelines

"Don't just wrap the camera. Own the memory."

• Engineering Manifesto

At BrewKits, we build mission-critical mobile infrastructure. We reject fragile abstraction wrappers, unbounded memory allocations, and inefficient platform-channel roundtrips.

Every engine in our ecosystem is governed by three industrial rules:

1. Zero-Copy Memory Pipelines: We eliminate CPU-side memory duplication. Physical buffer pointers (NativeBuffer, DMA, SurfaceTexture, CVPixelBuffer) route directly into reactive GPU render layers and ML inferencing engines.
2. Deterministic Lifecycle & Concurrency: Concurrency is strictly bounded with scoped mutexes (withLock), atomic operations (compareAndSet), and lifecycle-safe cleanup to guarantee zero memory leaks and crash immunity across configuration changes.
3. Validated in Commercial Production: We don't publish theoretical code. Our libraries are battle-tested in commercial apps shipping on the Apple App Store and Google Play Store.

• Core Ecosystem

1. High-Performance Vision & Graphics Engines

High-throughput camera, rendering, and zero-copy data pipelines eliminating the cross-platform framework tax.

Repository	Platform	Architecture & Technical Highlights
kmp-visionx	KMP (Android, iOS, macOS)	VisionX HyperFlow Engine™: Dual native camera pipelines (Camera2 / AVFoundation) unified under Compose Multiplatform with manual ISO, shutter, tactile dials, and 60 FPS real-time processing.
kmp-zerocopy	KMP & C++ / JNI	Direct Hardware Buffer Bridge: Direct DMA pointer mapping (NativeBuffer), sub-microsecond frame access, and zero CPU memcpy to keep memory bandwidth at ~0 MB/s CPU under continuous ML load.
hyper_render	Flutter & Dart	Single-RenderObject Layout Engine: Renders HTML, Markdown, and Quill Delta in a single unified RenderObject. Full support for CSS float, flexbox, grid, CJK Ruby/furigana, and cross-document selection.

2. OS Scheduling & Background Execution

Industrial background task runners adhering to modern Android WorkManager & iOS BGTaskScheduler OS execution constraints.

Repository	Platform	Architecture & Technical Highlights
native_workmanager	Flutter	Zero-Overhead Background Task Chains: Harnesses pure Kotlin CoroutineWorker on Android and Swift BGProcessingTask on iOS with zero Dart VM boot latency for unchained performance.
kmpworkmanager	Kotlin Multiplatform	Unified Multiplatform Job Scheduler: Orchestrates one-off, periodic, exact, and chained background jobs with advanced constraints, structured logging, and event-driven completion.

3. Enterprise Infrastructure & Reliability

Deterministic state synchronization, multiplatform permissions, and high-frequency event routing.

Repository	Platform	Architecture & Technical Highlights
Grant	Kotlin Multiplatform	ViewModel-First Permissions: Clean permission orchestration without Fragment/Activity bindings. Ready for Compose Multiplatform; completely resolves Android dead clicks and iOS deadlocks.
KRelay	Kotlin Multiplatform	Rotation-Safe Event Relay: Dispatches Toasts, Navigation, and System Events from shared KMP ViewModels to Android & iOS. Zero memory leaks, survives screen orientation changes.
flutter_debounce_throttle	Flutter & Dart	Enterprise Rate Limiter: Precision debounce and throttle engine with Redis-style rate-limiting semantics, zero dependencies, and over 360+ verified test cases.

• Production Flagship: LAM – Film Camera

Our architectural stack is proven in production. LAM is a commercial analog film camera app built on top of kmp-visionx and kmp-zerocopy.

• Sustained 60 FPS Viewfinder: Real-time sensor stream rendered via native GPU surfaces without frame drop or thermal throttling.
• Shared Compose UI: 100% of the vintage camera tactile interface, dials, and haptics shared across platforms.
• 16-Locale Localization: Comprehensive internationalization across Asian and Western markets.
• Independent Native Pipelines: Android Camera2 hardware level 3 + iOS AVFoundation Pro-stream integration.

• Engineering Standards & Contribution Quality Gates

We enforce strict quality gates across all modules:

• Test Execution: Automated test verification via AGP 9 KMP toolchain:

  # Run shared and host unit tests
  ./gradlew testAndroidHostTest test
  
  # Run Tier-3 zero-copy JNI regression net
  ./gradlew :kmp-zerocopy:connectedAndroidDeviceTest

• Coverage Discipline: Committed Kover regression floors enforced across all 13 SDK modules and shared app logic.
• Static Quality: Clean Detekt inspection required on all merge requests (./gradlew detekt).
• Memory Safety: Scoped native pointers with atomic reference counting. No unbounded static collection leaks.
