Founder and CEO, Seller Assistant
I build the software Amazon sellers use to decide what to buy, from whom, and at what price.
The story
I started as an Amazon seller. Like most online arbitrage and wholesale sellers, I spent my days in spreadsheets and dozens of Amazon tabs, checking each product by hand. In July 2019 I launched a tool to do that work for me. Other sellers asked for it, and it became Seller Assistant.
I still sell on Amazon. I own an Amazon wholesale business. A team runs it day to day, and it sources with Seller Assistant, so I test every feature as a seller before our customers see it.
Today Seller Assistant is a browser extension and web app that covers the full sourcing workflow: product analysis on Amazon pages, supplier price lists, IP and restriction checks, purchase orders and repricing. I lead product, engineering and strategy, and I still write code.
At our peak we were more than twenty people. In 2026 I rebuilt the company around AI agents. Today five people run Seller Assistant, and agents do much of the work across engineering, support, marketing and operations.
Before Seller Assistant I spent seven years in executive roles in Belarus and worked as a product manager in San Diego. I hold degrees in computer engineering and law.

Original work
Each one started as a problem I had as a seller.
A browser extension and web app that puts profit, risk and sales data on every Amazon page, then carries the seller from a supplier price list to a purchase order. Calculator, IP checks, stock and restriction checks live in one tool.

Impact Sellers scanned 13.5 million supplier lines with it in one year.
One of the first MCP servers for Amazon resellers, also available as an app in ChatGPT and in the Claude directory. Sellers run sourcing, repricing and purchase orders from AI assistants.
Impact Brought AI agents into the daily work of wholesale sellers.
An Amazon repricer that uses each product's real landed cost, so a price change never drops below the seller's margin.
Impact Closes the loop from sourcing to selling in one system.
AI-native company
In 2026 I rebuilt Seller Assistant around AI. We went from more than twenty people to five. AI agents now do much of the daily work in every part of the company, and people review and decide.
When people moved on, we did not rehire for the role. AI agents took over that work. Everyone who stayed got AI tools for their own job, and their work grew in scope.
Research
The first data report on Amazon wholesale built from real supplier price lists, not surveys. I wrote it and published it free under CC BY 4.0.
