• Architected a multi-tenant personal finance and life-admin platform by orchestrating autonomous subagents in Google Antigravity and generating a TypeScript, React 19, and Tailwind CSS codebase via OpenAI Codex; deployed live on Firebase Hosting. • Built an off-main-thread AI document classification engine using Web Workers and @huggingface/transformers (ONNX ModernBERT) with WebGPU acceleration and a WASM/CPU fallback, keeping the UI responsive during uploads. • Engineered a hybrid document-extraction pipeline (Tesseract OCR, PDF.js, regex rules, and multimodal LLM fallback) with a weighted, multi-signal duplicate-detection algorithm and document-lineage tracking, keeping extracted data structured, deduplicated, and audit ready. • Added a Service Worker PWA caching layer for full offline usability, plus speculative route-prefetching (requestIdleCallback) to warm JavaScript bundle chunks during idle browser frames. • Designed a zero-knowledge encrypted vault: client-side AES-256 encryption with PBKDF2 (100,000-iteration) key derivation, so unencrypted data never reaches the server. • Authored 520+ lines of Firestore security rules enforcing per-user subcollection isolation, field/type validation, and file-size limits to prevent privilege escalation. • Deployed a serverless background worker on Google Cloud Run (Docker, Express 5) running scheduled jobs for Firebase Cloud Messaging push notifications and token cleanup.
