Sergei Zdorenko

Sergei Zdorenko is the founder of AIOS Cortex, a San Francisco AI automation agency that helps small businesses install practical AI workflows, agents and automations. He spent six years in software QA before that: four at Premium Soft Labs in San Jose testing mobile apps across device farms, then almost two at Meta via HCLTech (May 2022 – March 2024, Menlo Park), coordinating offshore testing teams, writing test strategies across core products and driving quality bars for shipping features. AIOS Cortex's core offer is the AI Efficiency Sprint, a 7-day implementation that identifies bottlenecks and installs one to three AI systems: AI receptionists and lead follow-up, inbox and reply templates, CRM, email and calendar automations, SOP libraries and knowledge bases, dashboards. The focus is implementation, not AI hype: clear workflows, simple SOPs, Loom walkthroughs, systems clients can run themselves. Sergei is a graduate of one of AI Start Academy's first bootcamp cohorts. At AI START academy he teaches what he runs in his own agency: Claude Code and the Claude desktop app, skills and routines that work while nobody is at the keyboard, and the automation builds students need to go from a first client audit to an installed system.
