Key Projects
AI Task Delegation Assistant
2025
• Built entirely in n8n using a multi-agent architecture: a central controller routes commands to specialized workflows
(Email, Calendar, Research, Content Creation), so tasks like meeting scheduling run seamlessly across agents. Integrated
an AI-powered parameter extractor for natural-language inputs, Slack notifications for real-time alerts, and a Pinecone
knowledge base for document Q&A. The modular design means new agents (e.g. finance, CRM) can be added without
altering the core flow, showcasing scalable, extensible automation with n8n.
Cloud Migration Framework-
• Contributed to the development of standardized AWS migration methodology with comprehensive documentation,
assessment tools, and governance procedures. This framework reduced migration timelines by 40% while ensuring
consistent security controls and compliance across all migrated workloads.
Smart Contract Transaction Monitor (Ethereum) with n8n-
• Built an event-driven monitoring pipeline using n8n to track on-chain Ethereum smart contract interactions in real time.
Leveraged webhooks and Etherscan API to detect function calls, failed transactions, and contract events, then routed
alerts to Discord for community transparency and operational awareness.
• Automated JSON parsing and status validation allowed instant detection of transaction anomalies, reducing
time-to-diagnosis by 60%. Used in multiple testnet airdrop campaigns to ensure delivery success and audit integrity.
AWS Health Alert Workflow with n8n
2024
• Designed and deployed a serverless automation workflow using n8n to monitor AWS Health events and trigger instant
alerts via Slack and email. Integrated with AWS SDK to pull event data, apply conditional filters for severity, and enrich
alerts with contextual metadata for faster triage.
• Reduced incident response times by 40% and eliminated manual checks for infrastructure health across EC2, RDS, and
IAM services. This proactive alerting system improved system resilience and maintained 99.9% uptime for client-facing
environments.
Observability Dashboard
2024
