AdTech Operations and Engineering · Los Angeles, CA
I run programmatic advertising and build the tools that run it. Seven years in the trade: managing up to $1.2M a month in DV360 and The Trade Desk spend, then coding the platforms, simulators, and agents that make that work faster and more transparent.
BidLab (Swift / SwiftUI, MIT) The flight simulator for programmatic advertising. A native macOS app that teaches the math and operations of programmatic by doing it: 9 role-based paths, 124 cited interactive lessons, 9 role certification exams, and a math-true Trading Floor that runs 50,000-auction simulations (first and second price, log-normal markets, publisher floors) scored against the profit-optimal bid. Around 12.9K lines, 400+ known-answer checks.
Programmatic Skills (Python, MIT) A vendor-neutral agent-skills package that turns any AI assistant into a programmatic trader, analyst, and ad-ops specialist across five DSPs (DV360, Google Ads, Amazon DSP, StackAdapt, The Trade Desk). 72 documentation-cited skills, 7 specialist agents, 14 workflow loops, no-credential calculators, and read-only report pullers. Read-and-recommend by design and human-gated, matching where the platforms' own agents sit today.
SPO Auditor (Python, MIT)
A supply-path transparency auditor. It walks each impression's supply chain against
ads.txt, sellers.json, and the OpenRTB schain object, then flags unauthorized sellers,
hidden hops, and fee-leaking resold paths. The open primitives, finally tied together in one tool.
AdCP Trader (Python, MIT) A buyer-side trading agent for the Ad Context Protocol (AdCP, built on Anthropic's MCP). It plans and recommends like a trader, then refuses to spend a dollar without passing hard budget caps, a policy engine, and a human approval gate. The buyer's brain the protocol does not ship.
CartoChrome A health-access score for every US ZIP code. PostGIS spatial analysis over 21 public data sources covering 4M+ providers.
Nuvestan An AI-powered personal-finance platform with banking integrations and AI coaching. 226 automated tests.
Stanford BIOE 230 Interactive An AI-assisted learning platform adopted by Stanford Bioengineering: 180 modules, a contextual AI tutor, and 960 practice problems.
Confidential Programmatic Retail-Media Startup · CTO and Acting COO · Apr 2025 to Mar 2026 Programmatic advertising and retail-media platform for regulated industries. I coded the operating and reporting platform from scratch in Python and Django (cutting third-party tooling cost from $4,300 to $1,534 a month), ran a $300K to $500K per month business across 200+ advertiser accounts at 85% retention and 85% gross margins, built the data and measurement stack (a CDP of 21M+ profiles with a custom pixel and closed-loop order-level attribution) and a from-scratch shoppable ad-unit builder, and led a 15-person organization.
Causal IQ · Senior Account Operations Manager · Jun 2019 to Mar 2025 Managed $900K to $1.2M per month in programmatic spend across DV360, The Trade Desk, Yahoo, Xandr, and YouTube, ranking #1 or #2 of 22 managers on margin. End-to-end campaign operations across display, video, CTV/OTT, native, audio, and DOOH for healthcare, legal, retail, automotive, political, and public-health clients. Built Python and Pandas tooling adopted company-wide (recurring reporting went from about 6 hours to 6 minutes).
