Promptfoo discovers and eliminates LLM risks before they reach production through automated red-teaming and vulnerability analysis. Our open-source, developer-first approach has made Promptfoo the most widely adopted LLM security tool, with over 200,000 users at companies like Anthropic, Amazon, and Shopify.

• Own company-wide technical strategy and product roadmap, balancing open-source community, commercial product, and research investments.
• Led technical due diligence for $23M+ in venture financing from Insight Partners and Andreessen Horowitz.
• Built and scaled the engineering team from founding through Series A, including hiring, leveling, and performance management.
• Led development of core evaluation framework, vulnerability scanning, and automated red-teaming capabilities.

Smile Identity provides ML-powered identity verification APIs used by banks, fintechs, and telcos across Africa. Promoted from Director to VP Engineering to VP Engineering & Head of AI within one year, leading teams building APIs that now process hundreds of millions of identity checks.

• Owned engineering org design, headcount planning, and hiring across backend and ML teams, growing to 20+ engineers.
• Transformed engineering velocity from weekly releases to continuous deployment, migrating to TypeScript, adding tests in CI, and leading ceremonies.
• Re-architected inference APIs on AWS Lambda, scaling from 1,000 to 1M+ users per day and cutting job time from 30+ seconds to 7 seconds.
• Built computer vision pipelines for liveness detection certification.
• Pitched, designed, and shipped a fraud detection product using 1-N facial recognition with embeddings and vector search.

Skeptical Investments is a micro-VC fund focused on early-stage technical founders, with investments in ML, infrastructure, and space startups.

• Created InstaSafe, a tool that automates YC-standard investment documents.
• Advise portfolio founders on ML, infrastructure, hiring, and fundraising strategy.

Arthena was a quantitative art investment platform backed by Anthemis, Foundation Capital, and Y Combinator. Built Arthena from idea to acquisition by Masterworks in 2023.

• Co-founded Arthena and led technical strategy; sat on board and led fundraising, including debt financing for a 9-figure investment vehicle in the auction guarantee market.
• Built and managed a cross-functional team of 20 engineers, data scientists, and analysts.
• Built data pipelines, quantitative research tools, and visualization systems to scale investment research and augment analyst decision-making.
• Developed valuation models on irregularly-sampled time series using graph embeddings, probabilistic forecasting with calibrated prediction intervals, and online learning with walk-forward validation.
• Designed micro-service architecture for data collection, feature engineering, backtesting, and reporting.

Matroid is a computer vision platform for creating and deploying detectors, now funded by NEA and Accel. I co-founded the company and built the initial product through our first fundraise.
