Sergei Iadrov

Automation and Integrations Engineer with 5+ years of experience building and maintaining production automation workflows, system integrations, and internal business tools.

Core platforms: n8n (incl. self-hosted) and Make. Built and supported hundreds of workflows used in daily operations, with focus on reliability, error handling, monitoring, documentation, reusable patterns, and long-term maintainability. Extends automation platforms beyond standard connectors when needed: custom scripts, custom API connections, and lightweight cloud-hosted helper services for cases where built-in platform features are not enough.

Works closely with business teams: maps how processes actually run, identifies bottlenecks and error-prone handoffs, turns them into practical automation opportunities, builds working solutions from prototype to production use, and improves them based on real observations and user feedback. Experienced across CRM, finance, operations, reporting, back-office workflows, and AI-powered data processing. Uses AI tools to accelerate learning, scripting, and solution prototyping.
