I build AI systems for lending, and the risk controls that govern them.

Credit policy, loss forecasting & fair lending across a $275M+, five-brand portfolio, instrumented with an AI/LLM analytics stack I built and backed by published research on AI in financial risk.

About

Lending decisions happen at machine speed now, and I work on both sides of that. I build AI systems: agentic workflows, MCP servers, Snowflake and Python pipelines. And I build the risk controls that keep them honest, from model-risk management to fair-lending and explainability testing. My field isAI / algorithmic risk in financial services (fintech lending).

Today I run risk and business intelligence atFairSquare, a multi-brand SMB lender (brands include National Funding). I'm the sole risk & BI owner across five lending brands, carrying nine-figure annual originations and the surveillance, forecasting, and executive-reporting stack behind it, built from zero.

The thread through everything I do: finding the number everyone else missed. A seven-figure-per-month write-off reconciliation gap, now fixed company-wide. A syndication expansion led under incomplete data with 3-scenario stress analysis. An eight-figure favorable swing in 2025 net charge-offs, traced to specific cohorts on the book I instrument.

My toolkit is the full credit-risk stack (PD/LGD/EAD modeling, vintage and roll-rate analysis, risk-based pricing, line management, and fair-lending compliance under ECOA/FCRA/TILA) built on Python, SQL, Snowflake, dbt, and Tableau, and increasingly automated by an AI layer I engineered: custom Claude skills, MCP integrations across Jira, dbt, Domo, and Microsoft 365, LLM-generated executive commentary, and a governed semantic layer designed for AI consumption.

Outside the day job I research how AI is rewiring financial risk. That work is published in IEEE venues with 40+ citations, featured in the Free Press Journal, and quoted in Republic World and NDTV.

Experience

  1. Senior Business Intelligence & Risk Analyst · FairSquare (multi-brand SMB lender; brands include National Funding)

    Jun 2024 – Present
    • Sole risk & BI owner across 5 lending brands. Own the weekly executive report read by 85+ leaders including the C-suite on nine-figure annual originations. Rebuilt it from scratch, cleared through one SVP and three VPs weekly, with LLM-generated macro commentary for non-analyst readers.
    • Built the AI layer: custom MCP servers wiring Claude into Snowflake, dbt, Jira, Domo, and Microsoft 365; a reusable Claude skills library; and agentic workflows that turn raw stakeholder asks into scoped, executed work. Plus the governed AI-ready semantic layer with an LLM evaluation harness.
    • Called the risk right under ambiguity: variance attribution traced an eight-figure favorable swing in 2025 net charge-offs to specific cohorts, and a syndication expansion built on a 3-scenario stress model with incomplete data finished well past target.
    • Stopped bad numbers before the board saw them: a 2× funded-dollars overstatement, a growth misstatement, and a cross-join defect inflating a nine-figure metric by five orders of magnitude. Turned a seven-figure-per-month reporting gap into standing company protocol.
    • Re-platformed the money-critical reporting: moved month-end accounting and securitization (facility tapes, SPV excess-spread) off legacy SQL Server onto Snowflake + dbt. June close reconciled loan-for-loan, and 100% of external-auditor discrepancies were root-caused and closed across two audit cycles.
    • Led the BI re-platform: own Risk & Portfolio workstreams of a company-wide Domo-to-Tableau migration (400+ assets); standardized KPIs across all five brands, cutting manual reconciliation ~30%; coached 16 analysts and 3 interns in the domain.
    • Shipped fast and self-directed: cut the weekly performance review from 2 days to same-day and closed 68+ tickets across six departments in H1 2026, most self-scoped straight from stakeholder conversations.

  2. Student Analyst, Economic Research & Forecasting · Pacific Life

    Jan 2024 – Jun 2024
    • Built 4-quarter macro forecasting models (ARIMA, LSTM, Random Forest, Prophet) on Bloomberg Terminal data; ARIMA won on out-of-sample accuracy. Delivered an interactive Streamlit forecasting dashboard and presented to senior research leadership.

      Live · no charting library

      Three models from my day job, live in your browser. Drag the assumptions and watch the portfolio respond. It is the same math behind loss forecasting, delinquency surveillance, and pricing on a $275M+ book.

      Vasicek single-factor model, the Basel II framework behind bank capital rules. Expected loss, 99.9% VaR, and the capital buffer between them.

      Built from scratch with no charting library: Vasicek/Basel II capital math, delinquency roll-rate mechanics, and APR construction, straight from the day job.

      Projects

      Property Analyzer

      A real-estate underwriting engine that runs entirely in the browser: short-term + long-term rental analysis, cost-segregation tax depreciation, 3/5/10-year profitability, a recommended offer price, and a weighted 0–100 rating, all from nothing but an address (RentCast autofill, every assumption editable, live recompute). Full analyses encode into shareable URLs. Built with Next.js 15 + React 19 through AI-assisted development, with the finance engine regression-tested against the original Excel model.

      Kite Algo Bot: Automated Trading System

      GitHub ↗

      A rule-based algorithmic trading system for Indian equities (Zerodha Kite Connect) with one shared decision pipeline across backtest, paper, and live modes. An order only fires when every gate passes: signal-quality score, risk:reward, position sizing, margin, session timing, and kill switches (the same risk-controls discipline I apply professionally). Below: a real backtest replay from that pipeline.

      Backtest Replay: Swing Style, 365 Days, US Large-Caps

      Generated by the bot's real decision pipeline on synthetic market data over a config-driven US large-cap universe, the same code that runs paper and live modes. A demo of the system's mechanics (gates, sizing, kill switches), not a performance claim or investment advice.

        Migrate the Mess, or Mess Up the Migration

        What the AI era demands from your semantic layer. AI agents now consume BI metrics built for human eyes, and a migration is the once-a-decade window to fix that. Centerpiece: a lending case study where three versions of “Delinquency Rate %” silently disagreed in executive reporting for over a year, and the five properties (canonical definitions, explicit grain, logic separation, rich metadata, governed ownership) that make a metric layer AI-ready. Features practitioner interviews across Domo, Tableau, Looker, Power BI, and Qlik.
