Work History

I'm an AI Engineer that loves building products and web apps that can impact millions of lives

Columbia University - Lamont-Doherty Earth Observatory

Research Assistant โ€” Data Valuation for Ocean fCOโ‚‚ Prediction

January 2026 - Present

Cooperative Game Theory & ML

  • Conducting a data valuation study for ocean fCOโ‚‚ prediction using cooperative game theory, exhaustively enumerating all 2ยนยณ = 8,192 source coalitions across 13 observational datasets (~300K samples) and training XGBRegressor models per coalition against a held-out North American Subtropical task set.
  • Implemented 8+ valuation methodologies โ€” exact Shapley, Banzhaf, Beta Shapley, Least Core (LP-based), Complement Shapley, Weighted Banzhaf, Shapley-Taylor order-3 interactions, and Weighted Shapley with geographic weighting schemes โ€” to quantify individual and joint source contributions.
  • Developed a novel Interaction-Aware Two-Phase Valuation framework that captures higher-order synergy and redundancy effects missed by standard marginal-contribution methods, with detailed negative source removal impact analysis.
  • Built a reproducible research pipeline with resumable .npz coalition caching, joblib parallelism, and Cartopy Robinson projection geospatial visualizations, producing 51+ analytical graphs across two notebooks and a full research report.
Columbia University โ€” IEOR Department

Teaching Assistant โ€” Algorithmic Trading (IEOR E4733)

January 2026 - Present

Market Microstructure & Trading Systems

  • Supporting graduate-level instruction in algorithmic trading covering market microstructure theory, optimal market-making (Avellaneda-Stoikov), optimal execution (GLFT), and high-frequency trading system design.
  • Guided students through hands-on implementation of HDF5 data pipelines, event-driven trading architectures, and statistical signal construction for systematic strategies.
Paperchase Inc.

AI Engineer

May 2024 - August 2025

Predictive Analytics and Product Development for Hospitality Finance

  • Engineered an end-to-end financial intelligence platform combining AutoML forecasting, multi-agent LLM commentary, and drill-through P&L/Balance Sheet analytics used by CFOs and finance leaders across 200+ hospitality clients.
  • Built scalable Azure-based microservices (FastAPI + Functions + SQL Server) to operationalize forecasting, KPI computation, and AI-generated variance analysis, reducing reporting latency by nearly 40%.
  • Led the development of a multi-agent reasoning workflow that produced account-wise financial insights, automated variance explanations, and executive-grade commentary for P&L and Balance Sheet statements.
  • Designed and deployed data pipelines and forecasting frameworks using SARIMA, LSTM, N-BEATS, AutoTS, and NeuralForecast, standardizing financial projections and saving 15โ€“20 hours/month of manual effort per client.
