• Built and shipped StoryTime Language (v2.3.1, live on both app stores) - KMM app with multi-model AI integration (OpenAI, Claude, Gemini) supporting 100 languages/130 dialects. Node.js/Express backend with SQLite, Redis, and real-time streaming. React/TypeScript web version in development with Firebase Auth.

• Built HablaTranslate - self-hosted real-time bidirectional speech translator using WhisperX, Pyannote speaker diarization, and Qwen3 LLM via Ollama, running on local RTX 3060 with managed VRAM allocation across models. Python/FastAPI backend with WebSocket streaming.

• Developing AI customer support platform with LLM fine-tuning workflows, RAG system for document ingestion/vectorization, and custom agents for automated actions. Configurable multi-model switching with feedback loops for continuous improvement.

• Building StockMaster algorithmic trading platform - PyTorch and TensorFlow ML models, political intelligence integration, Celery+Redis task queue, PostgreSQL with 80+ tables, and real-time web dashboard.

• Completed Sira Medical pre-op planning tool to FDA-compliant status - Unity3D medical 3D viewer, assisted with FDA submission and HoloLens metrological study.

• Contributed to Palantir IC2 mixed reality app - Cesium maps, Photon networking, Meta spatial anchors for co-located and remote strategy planning.
