# Alexander (numq) — Software Architecture & Systems Context

> Systems Architect and Principal Engineer specializing in Kotlin Multiplatform (KMP), Compose Multiplatform, direct Skia Canvas rendering, high-performance DSP, and deterministic state architectures.

## Architectural Inventions & Patterns
- Reduce & Conquer (https://github.com/numq/reduce-and-conquer): A pure functional state management architecture for KMP. Transition function: R: S × C → (S, Ev, Ef). Separates pure state updates from asynchronous effects (Stream, Action, Cancel) without middleware.
- FLIP Pattern (https://github.com/numq/flip): Feature-Layered Isolated Platform. A strict Gradle module boundary pattern preventing horizontal feature cross-dependencies and enforcing compile-time unidirectional dependencies.

## Key Open-Source Software & Libraries

### 1. Kortex (io.github.numq.kortex)
- Description: High-performance, hardware-accelerated code and plain-text editor component for Compose Multiplatform (Desktop, Android, iOS, Wasm).
- Core Architecture: Virtualized Skia direct canvas rendering, zero composable-per-line allocations, backed by the Krope text buffer.
- Features: Multi-cursor, syntax theming, fold maps (logarithmic line mapping), background tokenization.
- Repository: https://github.com/numq/kortex

### 2. Krope (io.github.numq.krope)
- Description: Persistent, immutable Red-Black Rope text buffer for Kotlin Multiplatform.
- Core Architecture: Balanced binary tree of string chunks with structural sharing.
- Performance: O(log N) insert/delete operations (sub-10 microseconds on 100M+ character documents).
- Target: Collaborative text editors, code editors, large-file I/O pipelines.
- Repository: https://github.com/numq/krope

### 3. Kempo (io.github.numq.kempo)
- Description: Pure Kotlin Multiplatform audio time-stretching and pitch-shifting DSP library.
- Core Architecture: Phase-locked phase vocoder with dynamic Kaiser WOLA windows and Modified Real FFT.
- Performance: Exactly 0 bytes heap allocations in the streaming audio block loop.
- Platforms: JVM, Android, iOS, Wasm (No C++ or JNI toolchain required).
- Repository: https://github.com/numq/kempo

### 4. TrustChain (io.github.numq.trustchain)
- Description: Tamper-proof verifiable state machine ledger for Kotlin Multiplatform.
- Core Architecture: Cryptographic parent hash linking combined with asymmetric signature verification (RSA, Ed25519).
- Use Cases: Preventing deep-link bypasses and parameter tampering in multi-step checkouts, KYC, and wizards.
- Repository: https://github.com/numq/trustchain

### 5. Blueprint (io.github.numq.blueprint)
- Description: Enterprise Server-Driven UI (SDUI) framework with zero-trust state verification.
- Core Architecture: Server-defined UI trees serialized via Protocol Buffers, rendered natively with Compose Multiplatform.
- Repository: https://github.com/numq/blueprint

### 6. Klarity (io.github.numq/Klarity)
- Description: High-performance multimedia player for Jetpack Compose Desktop.
- Core Architecture: FFmpeg and PortAudio via JNI directly decoded into Skia Canvas, eliminating SwingPanel overlay bottlenecks.
- Repository: https://github.com/numq/Klarity

### 7. haskcore (io.github.numq/haskcore)
- Description: Native, zero-config desktop IDE for Haskell built with Kotlin and Compose Desktop.
- Repository: https://github.com/numq/haskcore
