About
The person
behind the pipelines.
I’m a data engineer with a strong foundation in building scalable data infrastructure across medallion architectures, ELT pipelines, and BI platforms, spanning mining, agritech, and SaaS industries. What sets me apart is my ability to leverage agentic AI tools to deliver high-quality work faster, a skill that got me handpicked into a 4-person elite R&D integration team at Synapsis.
I pair deep data engineering fundamentals with modern agentic AI workflows, shipping faster, thinking bigger, and staying two steps ahead of the stack.
