Featured Engineering Projects
01 · Distributed Data Platform — Reproducible, scalable market-data platform: ingests raw stock-minute data from object storage, validates and transforms it into analytical datasets, and serves them through distributed and local analytical engines. code
02 · VocalForge — Tencent AuK 1.5B speech generation & editing (TTS, content/acoustic/paralinguistic editing, enhancement, separation) on Kaggle’s free 2× T4 GPUs, with weights served from Kaggle datasets. code · Kaggle
03 · EdgeGuardAI — Modular, event-driven security system combining local face recognition and multi-sensor correlation to publish automated voice announcements via MQTT. code
