I'm Sergei Mostachev — a systems architect and senior software engineer specializing in CRM architecture, AI-driven automation, and telephony infrastructures. Since 2009, I've been building enterprise-grade solutions, and since 2016 I've been helping companies modernize their business processes through automation, Bitrix24 engineering, Asterisk telephony, and advanced AI workflows.
For many years I worked under the professional pseudonym "Anton Chekhov" while developing the Prigov.info brand. After registering my own company in 2021, I shifted fully to my real name — Sergei Mostachev — bringing forward all my accumulated expertise, portfolio, and reputation.
My work focuses on designing scalable digital ecosystems for international companies, implementing AI agents (voice + text), building n8n-based workflows, integrating complex telephony systems (Asterisk ARI/AMI), and developing microservices. I approach each project as long-term system architecture — not just "development," but measurable business transformation.
