01 / Featured Work

Work shown on equal ground.

Each project is treated as a proof point, not a hierarchy. The goal is to make the system shape, technical direction, and links easy to scan.

Agentic AI / Quant

Vibe Quant

case study soon

Autonomous agentic alpha discovery framework — LLMs orchestrate research, Qdrant stores vector memory, and a Rust-backed engine validates backtests.
