Problem

Teams often spend time manually moving information between applications, enriching data, sending notifications, and repeating predictable operational tasks that can be orchestrated automatically.

Approach

• Built trigger-driven workflows that ingest, process, store, and route information across connected services
• Integrated LLMs, REST APIs, webhooks, PostgreSQL, and custom processing steps into reusable automations
• Used LLM-based processing for classification, enrichment, routing, and decision-support steps where appropriate
• Added branching logic, retries, logging, and failure-aware handling for more reliable execution
• Structured workflows so individual components could be adapted to different business processes

Results

• Reduced repetitive manual work in AI-assisted business operations
• Created reusable automation patterns for lead handling, document processing, notifications, content workflows, and data enrichment
• Connected LLM capabilities with real business systems through APIs, databases, and event-driven workflows
• Improved reliability through explicit error handling and observable workflow execution
