About

Allen Arorong is a Microsoft Certified Power BI Data Analyst based in Iloilo City, Philippines. I have practical experience supporting Power BI dashboards, SQL reporting, data validation, report refreshes, and business reporting workflows.

My professional background includes Power BI development, PostgreSQL reporting, mortgage and financial services reporting, dashboard refresh support, UAT and production troubleshooting, SQL data validation, and Excel reporting. I have also developed hands-on portfolio projects using Tableau, Looker Studio, Python, and AI automation, with n8n as my primary workflow automation platform.

Through n8n, I have designed end-to-end solutions for CRM follow-ups, client onboarding, knowledge-base assistance, appointment scheduling, customer messaging, and automated reporting. These projects have given me practical experience with workflow logic, data mapping, branching, webhooks, APIs, AI models, integrations, and error handling.

I focus on n8n because its flexibility allows me to understand automation at a deeper technical level. While n8n, Zapier, and Make are different platforms, they share the same core automation concepts: triggers, actions, branching, data mapping, webhooks, and API integrations. My n8n experience therefore provides a strong foundation for building in Zapier and Make, which I am continuing to explore and plan to demonstrate through future projects. My goal is to help businesses improve dashboards, automate repetitive work, and connect data analytics with practical AI automation.
