   RAG precision, recall, F1

   What I built

   • Built and deployed a six-agent LLM system on AWS that turned a multi-week creative campaign workflow into minutes.
   • Built a schema-harmonization pipeline that cut a week of manual data reconciliation to about an hour.
   • Shipped a RAG retrieval system for a nonprofit with over 92% precision, recall and F1.

   stability accuracy across 7,000 formulas

   What I built

   • Built AI automation pipelines saving an estimated $4M a year and making chemists 15% more efficient.
   • Replaced manual visual inspection with a computer vision and LLM pipeline that judges formula stability at 99% accuracy across 7,000 formulas.
   • Wrote an R analytics pipeline for correlation and clustering that feeds formula optimization models.
3. 

   Machine Learning Engineer Intern

   Educational Testing Service · Princeton, New Jersey
   Jun to Aug 2024

   Built TensorFlow security features for the GRE, TOEFL, SAT and AP exams, now in production in ETS Test Security as a Service.

Each project with working code has its own page. Code is linked where the repository is public. The businesses I am building are under Ventures.

• Gridiron Oracle

  Causal forecasting and execution

  A live site that forecasts every NFL player's weekly stats using only what was known before kickoff, so each forecast is one you could have made at the time.

• Memory-constrained forecasting

  Shows that a forecaster with limited memory predicts electricity-price spikes better by keeping a few learned summaries than 14 times as much raw history.

  191919%

  lower tail-forecast error at equal memory, best budget

• Prediction-market trading system

  Python signals, C++20 execution

  Spots price gaps between prediction markets and places the trades through an engine fast enough that the wait is measured in microseconds.

• Satellite constellations for disaster response

  Autonomous orbital optimization

  Designs satellite constellations that revisit disaster areas sooner, using a learned model in place of hours-long orbit simulations.

  shorter revisit gap than the standard 48-hour single-satellite benchmark

• Veil

  Cross-platform federated learning SDK

  Lets an app personalize what it shows without collecting user data: the model learns on the phone or in the browser, and the raw data stays there.

Businesses I am building or helping to build, and where each one stands today.

• Mainstay

  Live

  Gives a business one view of its calls, sales and ad spend, so the owner can see which marketing brings in customers.

  Live with a pilot venue.

  • An AI answers the phone when no one can, books and changes bookings, and hands the call to a person when asked.
  • Talk of injury, legal trouble or insurance gets no AI answer. A person is alerted right away.
  • Each business's data is walled off inside the database itself, and the app refuses to start if that wall is missing.
  • A release will not go out while a call is in progress.

  Roadmap

  1. Answers calls and books for the pilot venue: Done
  2. Serve a second and third kind of business with one shared booking and intake setup: In progress
  3. Turn on email replies and texting: Planned

  Breakdown: Mainstay

• NavisTeams

  Live

  Staffing software for multi-location businesses, on web, iOS and Android, that I am joining as a co-founder after mapping the whole system.

  Private beta, by invitation.

  • Managers build and publish schedules. Staff claim open shifts, swap shifts and ask for time off.
  • Floor staff clock in at a shared kiosk with a PIN.
  • Hours flow to QuickBooks payroll, and sales sit next to labor cost.
  • An AI assistant answers questions about hours, pay, schedules and expiring documents.

  Roadmap

  1. Scheduling, time clock, payroll sync and the AI assistant are built: Done
  2. Private beta with the first operators: In progress
  3. Switch on the AI schedule assistant, then add paid plans: Planned

• BizSi v2

  Building

  The next step of Mainstay: an AI voice agent that picks up a business's calls almost at once.

  Not taking real calls yet.

  • An owner types a phone number, website or name and talks to an agent that has already found their business.
  • Every sentence is checked before it is spoken, in English and Spanish. A sentence that fails is dropped, never rewritten.
  • What a caller says is never treated as a fact about the business.

  Roadmap

  1. Reply checks and call-safety rules are built: Done
  2. The first real call: In progress
  3. Real callers, then a pilot with businesses: Planned
