Built a multi-agent AI coaching system from zero to production, enabling 24/7 multilingual operation with 10+ agents across two clusters (Coaching and Sales). Implemented hexagonal architecture with output contracts, context compression, agent-versioning, and DB-centric state sharing; resilient orchestration via n8n and Redis. Achieved coaching quality comparable to humans, with ongoing multilingual support (ES/EN).
Built consulting practice infrastructure entirely self-hosted on personal VPS. Full ownership and control, near-zero operational cost. Deployed a full stack (React.js frontend, Express backend, PostgreSQL) and a custom CRM pipeline using n8n; set up Poste.io mail server and Lucy AI assistant on Ollama (proof of concept). Self-hosted stack runs 24/7 with minimal maintenance. Automated sales, CRM, and email-nurturing pipeline.
