I’m a Data and Analytics Engineer focused on building clean, reliable pipelines and analytics solutions that help hospitality and financial advisory teams turn complex CRM and transaction data into fast, actionable insights. My expertise centers on the modern cloud data stack: Snowflake (SnowPro Associate certified), dbt, and AWS. I use these tools daily for ingestion, modular transformations, governance, orchestration, and production deployments, delivering end-to-end flows for CRM data across hospitality and finance. I integrate AI practically into data engineering workflows, for semantic querying, forecasting, and agentic capabilities, to make pipelines smarter and reporting more intuitive. Before moving fully into data engineering, I built backend systems and production Python applications. My foundation is in civil engineering (Bachelor’s degree, topnotcher in the licensure exam), where I worked across construction, procurement, real estate, manufacturing, design, and logistics, experiences that taught me end-to-end ownership and solving under real constraints. As a lifelong learner, I’m active in Cebu’s tech community. I founded Data Engineering Cebu, a space for data professionals to connect, share knowledge, and grow together.
