Engineering resilient, local-first applications, native Android networking utilities, and forensic media salvage pipelines. Focused on deterministic state management, low-latency client-side DSP, offline-first architectures, and multi-platform CI verification.
| System | Domain & Architecture | Core Specifications & Verified Metrics |
|---|---|---|
| 🎬 CapCut Cache Recover | Forensic Video Stream SalvagePython 3.9–3.13 ISO BMFF H.264 / AAC Tkinter |
• Bitstream-exact salvage reconstructing unfinalized moov atom headers without re-encoding generational loss.• Multi-platform automated CI matrix (Python 3.9–3.13 across Linux, macOS, Windows). • Standard library core with zero required external C runtime dependencies. |
| 🌌 Birdsong Visualizer | Bio-Acoustic Signal ProcessingWebGL GLSL Shaders Web Audio API TypeScript |
• Real-time 2048-point Fast Fourier Transform (FFT) spectral decomposition at 60 FPS. • Bandpass frequency isolation calibrated to the 2 kHz – 10 kHz avian acoustic spectrum. • 100% offline client-side DSP pipeline with zero cloud round-trip latency. |
| ⚡ FocusFlow | Local-First Productivity EngineReact 19 TypeScript 5.8 Capacitor 8 Tailwind CSS v4 |
• Local-first state engine with zero telemetry and structured atomic persistence. • Native persistent alarms configured to bypass Android battery Doze mode. • Lite optimization mode eliminating GPU-composited backdrop filters for low-power devices. |
| 🛡️ Pickko AdGuard | On-Device Android DNS FirewallLocalVpnService Java Capacitor 8 React 18 |
• Intercepts UDP port 53 packets locally on a virtual TUN loopback interface (10.1.1.1/24).• In-memory radix domain matching with synthetic RFC 1035 NXDOMAIN response injection. • Upstream forwarding via protect(DatagramSocket) with zero root requirements. |
- Deterministic Offline Execution: Applications operate independently of central cloud infrastructure. Data serialization and processing execute locally on-device.
- Low-Level Protocol Parsing: Parsing raw bitstreams and network datagrams (ISO BMFF boxes, NAL units, UDP DNS packets) directly in memory without bloated abstraction layers.
- Continuous Verification: Repositories maintain automated CI test matrices across target environments (Python versions, node runtimes, modern Android SDKs).
- Minimal Dependencies: Preference for language standard libraries and platform-native primitives over heavy third-party framework dependencies.
