SEORecheck was created by Bohdan Kossak, a software engineer from Lviv, Ukraine. He holds a master’s degree in mathematics and computer science from Ivan Franko National University of Lviv.

From 2005 to 2017 he worked at Ericpol, later part of Ericsson, including as head of IT, while freelancing and building his own projects. One of them, ihero2012.com and later geroj.com, ran from 2008 to 2012 and had more than 15 million visitors, mostly from Eastern Europe and Asia. Both sites have since closed.

In 2018 he co-founded CryptoLions and became its CTO. The company is an EOS block producer; its team built and ran Jungle, the largest public EOS testnet, where the EOS mainnet launch was prepared. There he created Simple Assets, an open standard for digital assets (NFTs and tokens) on EOSIO blockchains, with Simple Market built on top of it as a marketplace. The game kolobok.io was for a time among the top five blockchain games across all blockchains on DappRadar.

He also founded v4v.ai, an AI service that turns products and ideas into video and image content, along with other projects.

SEORecheck

SEORecheck is his 2026 project. Its approach is an engineer’s: every finding is backed by evidence from your own pages, fixes are ordered by impact, and the result is rechecked later on the same pages.

SEORecheck is operated by FOP Kossak Bohdan Orestovych, Lviv, Ukraine. Contact details
