About

I founded FeedArc after running into the same product feed problems every e-commerce founder eventually hits: feeds break silently, errors compound across channels, and the existing tools either cost enterprise rates or leave you guessing what went wrong. FeedArc is the tool I wish existed when I was managing my first Google Shopping account — quality grades that tell you what to fix, AI-powered optimization that respects engineering correctness, and a price point that works for stores below the Feedonomics enterprise tier.

My work focuses on the unglamorous middle layer between e-commerce platforms and advertising channels: feed validation, taxonomy mapping, GTIN integrity, multi-currency edge cases, and the GA4-to-channel feedback loop that turns analytics into bidding signals. The articles I publish here are the technical answers I wish someone had written when I was researching solutions — concrete tradeoffs, verified facts, no marketing fluff.

When not building FeedArc, I write about the engineering decisions behind ecommerce infrastructure and the SEO/SaaS strategies that actually move the needle for small teams. If you have a specific feed management problem, the fastest way to reach me is via the contact page or LinkedIn.
