Andrei Kushniarou
Data engineer — e-commerce & analytics
Lisbon, Portugal
I build the operational infrastructure for e-commerce brands on Amazon, Shopify, TikTok, Walmart — automated order processing, multi-channel fulfillment, intelligent warehouse routing, and the analytics that runs on top.
Currently working with brands at $5–10M/mo. Previously ran data at Arteza ($100M+ revenue, Inc. 5000 #32, top-50 Amazon seller) — built the full data stack from API ingestion to executive reporting.
Now consulting independently under SellerFlux for e-commerce clients. Outside of client work, I publish on-chain research on Dune — DEX bots, stablecoin flows, fraud detection. Same engineering, different data.
Coding since 2001, data engineering since 2013, working with AI/ML since 2019, on-chain since 2020.
