Data Engineer & Solutions Developer

I build automated data pipelines, data warehouses, and analytics solutions that eliminate manual work and turn raw data into actionable insights. With 10+ years of experience in data engineering, analytics and building end-to-end solutions, I help businesses automate workflows, integrate APIs and data sources, build scalable data infrastructure, build custom UIs to simplify user experience, and turn existing data into meaningful dashboards and analysis. I focus on understanding the business problem first, then building solutions that are reliable, maintainable, and tailored to your needs. My goal isn't simply to deliver code, but to build systems that save your team time, reduce errors, and drive your business goals.
