I’m the founder of Ricardium—an AI-native economic intelligence platform.

Our flagship product, the Trade Pulse API, is built to be the best AI-native source for real-time and historical duty rates for any product traded across borders. It transforms fragmented trade rules and policy changes into structured, queryable trade policy intelligence by connecting each product’s duty rate to its origin, destination, and unique characteristics.

Most of the work on this site is one piece of the question Trade Pulse API solves. I’ve estimated pass-through along supply chains, the real-time cost of the 2025 tariffs, and how the indices investment funds track distort sovereign debt pricing.

Uncertainty hurts!

This project develops a platform to monitor trade policy, exploiting my domain expertise, by providing updates and predictions. I estimated tree-based ML models and standard univariate models for over 10,000 internationally traded products.

Built on the GCP platform for storing model artifacts and underlying data; an LLM-powered RAG makes querying and understanding model results as simple as asking for the trade intelligence of product X, of your choice.

I try to stay at the forefront of the AI evolution. I have built some of the following.

RAG based on Langchain or Langgraph
Context graph using Neo4j
Auto system prompt optimization

I also coded and deployed some end-to-end apps. One is an accent reduction app—AccentFab— focusing on intonation training based on approaches from renowned language coach Dr. David Alan Stern.
