Science alone doesn't create value. Productionizing, automating, and scaling it does.
I build production systems that translate scientific models into actionable decision frameworks for high-stakes business problems under uncertainty.
Positioning
I work at the intersection of three things: science (causal inference, decision theory, economic modeling), engineering (production systems, automation, scalable infrastructure), and judgment (knowing what matters and when enough is enough).
Every project I take on follows the same logic: screen established science, adapt it to the use case, productionize it, automate it, and scale it — then build a learning loop so each cycle compounds. The goal isn't better analysis. It's faster, evidence-backed decisions.
Showcase
Impact Engine
Organizations invest in dozens of initiatives but rarely know which ones actually moved the needle. Impact Engine closes this gap — a config-driven Python ecosystem that runs a full decision loop in a single call.
Measure each initiative's causal impact with pluggable econometric models. Evaluate the strength of that evidence so weak estimates don't drive big bets. Allocate budget across the full portfolio under uncertainty. Scale the winners — then feed learnings back into the next cycle.
Four independent Python packages, each with its own CI pipeline and release cycle, wired together by an orchestrator at runtime. Grounded in econometrics and decision theory, shipped as tested, deployable, open-source software.
Impact
- Catalog AI – Causal Impact Framework: Developed the causal impact measurement framework for Amazon's Catalog AI initiative, leveraging randomized experiments to quantify the business value of product data improvements. Built production pipelines that measure customer impact, guide model development, and drive seller adoption with experiment-backed insights. Published in Harvard Business Review: Inside Amazon's AI Factory.
- Uncertain Decisions – Portfolio Allocation Framework: Designed a standardized framework to evaluate the return on investment (ROI) of major tech initiatives by aligning assumptions across teams, validating inputs, and conducting sensitivity and scenario analyses. Established ongoing tracking processes that refine projections and feed ROI data back into investment decisions through iterative refinement. Available as Working Paper: Science-backed Decisions for High Stakes Investments Under Uncertainty.
