Building High-Performance Systems & Local AI Runtimes
Hi, I'm SiChao (Ocean). I am an innovative developer passionate about artificial intelligence, game development, and creating seamless digital experiences. Exploring the intersection of clean code and creative design through standalone desktop applications, local neural models, and scalable architectures.
Open Source Projects & Systems
Dedicated documentation, architecture breakdowns, and pre-built distributions.
SubtitleGo (Subtitle Studio)
A standalone desktop speech recognition and subtitle editing studio powered by PySide6 and Qwen3-ASR (1.7B). Runs locally with smart silence pause detection, video preview sync, and SRT/WebVTT export.
OceanGo (AlphaZero Go AI)
Deep reinforcement learning Go engine implementing the core AlphaZero architecture with a 19-block ResNet (dual policy/value heads), 17-plane board state history with Ko rule handling, and batched PUCT MCTS with virtual loss. Engineered with a centralized GPU worker queue.
Bathyal (Project Management)
A lightweight, self-hosted web application for team project management. Built with PHP 8.3 and MySQL 8.0 featuring Kanban boards, full task lifecycles with subtasks, live time tracking, notifications, team roles, and REST JSON API endpoints.
Design & Architecture Principles
Local-First Execution
All compute, transcription, and tensor models execute strictly within local process memory. No user telemetry, no cloud subscriptions, and zero remote data transfer.
Direct In-Process Runtimes
Eliminating microservice and Docker overhead for desktop workflows. Deep integration with PyTorch, ONNX Runtime, and Qt GUI engines.
Hardware Acceleration
First-class support for NVIDIA CUDA (including RTX 50-series Blackwell), Apple Silicon Metal (MPS), and multi-threaded CPU execution.
Portable Distributions
Pre-packaged standalone ZIP bundles with embedded dependencies alongside clean, transparent step-by-step source build documentation.
Let's build something amazing together
Feel free to reach out to me via email or connect on GitHub. Whether you want to discuss local AI architectures, collaborate on open-source software, or share ideas, I'd love to hear from you.
