Bohdan Antonov

AI Product Engineer (E-commerce & SEO Automation)

Bohdan Antonov · Odesa, Ukraine (Remote)

I build production AI systems for e-commerce SaaS and SEO operations: RAG knowledge assistants for internal teams, vision+LLM product content generation at scale, and SEO intelligence workflows powered by real performance and market metrics.

Before AI, I worked in digital marketing and e-commerce operations (SEO/SEM and content). Since 2023 I’ve been at Horoshop (Cartum) across sales/partnerships and, since mid-2025, AI services R&D. I own system design, data pipelines, integrations, evaluation/guardrails, and production reliability end-to-end.
