Deep Dives & Systems

A look under the hood. Beyond the UI, I love exploring scalable architectures and building real-world solutions.

Problem

Crypto futures trading suffers from extreme volatility, high noise-to-signal ratios, and lack of visual feature explanations.

Solution

Developed an analysis-only futures prediction suite combining XGBoost classifiers and PyTorch LSTM sequence engines running under Nvidia CUDA, paired with FastAPI WebSocket streaming and transparent SHAP explanations.

Computer Vision / Accessibility

Problem

Visually impaired individuals face dangerous physical navigation challenges and lack real-time context of spatial changes.

Solution

Built a zero-latency spatial AI system using yoloe-26N-seg object locators, multiprocessing face identification queues (GIL-free), Gemini-3-Flash multimodal scene understanding, and an adaptive RAG memory using LlamaIndex.
