A tighter set of case studies, product concepts, and builds.
An AI-augmented qualitative coding platform that helps researchers maintain coding consistency through real-time audit alerts, deterministic embedding similarity, constrained LLM feedback, visual analytics, and collaborative inter-coder reliability workflows.
Built and evaluated Double DQN limit-order trading agents in the Bristol Stock Exchange simulator to test how reward design changes execution behaviour. The study showed that surplus-based rewards produced a more disciplined “earn the spread” policy with a higher Sharpe ratio, while profit-based rewards encouraged aggressive spread-crossing and more trades but weaker risk-adjusted returns.
AuthLens is a full-stack AI workflow platform that helps healthcare teams prepare prior authorization and appeal packets from synthetic or de-identified PDFs. It turns payer policies, denial letters, and patient-supporting documents into structured criteria, evidence matches, readiness reports, citation-checked drafts, audit logs, and exportable review packets.
