🚀 AWS & Databricks Certified Data Engineer | AI Automation & n8n Workflows | ETL | Infrastructure I build AI-powered automation and n8n workflows that don’t break under real-world conditions. Most automations fail due to poor data handling and API integration — that’s where I focus. I combine ETL, APIs and infrastructure to create reliable, production-ready systems. With 9+ years of experience across data engineering, database administration, and infrastructure, I design end-to-end systems where data, automation and AI work together seamlessly. 🔹 AI Automation & n8n Workflows (Production-Ready Systems) Most workflows fail at the data layer or between API steps — I design systems that handle these edge cases properly. Designed and implemented n8n automation systems integrating APIs, databases and AI services Built AI-powered workflows for: email automation and personalization support triage and classification data enrichment and decisioning Handled real-world issues like: inconsistent webhook payloads AI output breaking downstream steps retry logic, rate limits and failure handling Focused on building workflows that are: ✔ Stable ✔ Debuggable ✔ Scalable ✔ Easy to maintain 🔹 Data Engineering & ETL Modernization Designed enterprise ETL pipelines using SSIS, Python, PowerShell, Airbyte, dbt, n8n and Dagster Built AWS-based data platforms (Glue, Athena, S3, Lambda, Delta Lake) Databricks Certified Data Engineer with hands-on Spark transformation experience Migrated legacy SQL workflows to modular, cloud-native architectures 🔹 Senior SQL Database Engineering PostgreSQL, SQL Server, Oracle, MySQL Advanced indexing, partitioning, and query plan optimization High-availability architecture and zero-downtime migrations Production performance tuning and database automation 🔹 Infrastructure, APIs & Systems Integration This is where I differentiate. Most automation systems break not because of tools — but because of weak system design. I bring: API integrations across enterprise systems Networking and firewall awareness (Palo Alto, F5) Windows and Linux server administration Identity-aware integrations (Active Directory, secure auth flows) Docker-based deployments Because of this, I build systems that are: ✔ Secure ✔ Network-aware ✔ Scalable ✔ Operationally maintainable 🔹 Enterprise Impact Automated integrations between ERP, LMS, and third-party systems Reduced ~3,000 IT tickets per semester through workflow automation Led BI migrations and built executive dashboards (Power BI, QuickSight) Implemented monitoring, alerting, and governance frameworks 💡 Why Clients Hire Me Most freelancers focus on: automation tools or data pipelines or infrastructure I bring all three together. That means: fewer broken workflows better architecture decisions cleaner integrations stronger performance production-ready systems
