Top SchoolAnton Zaytsev is a Senior Software Engineer with 13 years of experience designing, building, and maintaining complex web systems, currently based in Petropavl, Kazakhstan. He has deep expertise in Ruby on Rails and a track record of modernizing large monoliths—having led a zero-downtime migration of a 500K+ LOC Rails app from 5.0 to 8.0. Anton combines product- and data-informed engineering, shipping an AI-powered design platform integrating Gemini, Replicate, and RunPod, and driving A/B experiments and SEO improvements that measurably grew organic reach. He has built resilient commerce infrastructure—real-time delivery tracking for 50K+ monthly orders, robust payment observability across Stripe/PayPal/Venmo, and conversion-focused fixes that reduced support load. Known for pragmatic end-to-end ownership, he moves between architecture, hands-on coding, and observability to solve thorny production issues. Colleagues describe him as a practical problem solver who blends Rails craftsmanship with emerging AI integrations.
