Versatile Analytics professional with over 3 years of experience in enterprise data environments. Proven expertise in architecting high-performance data pipelines, achieving an 85% runtime optimization for financial systems. Strong background in Python, SQL, and Power BI with a focus on translating complex datasets into actionable business intelligence and strategic decision support.

I'm a systems thinker who builds for production. I care about data quality first, then speed. I thrive in ambiguous problems where the data tells a story — and I believe good analysis should need no explanation.

Darrell Chew

My project work centers on rigorous data analysis and end-to-end data science processes. I design data pipelines that prioritize quality and reliability, build dashboards that translate complexity into insight, and develop full-stack data products that solve real business problems. Each project reflects my belief that good analysis requires clean data, sound methodology, and clear communication—turning raw information into decisions that matter.

I prioritize thinking over tooling. Architecture decisions, data modeling, and design direction are mine. Every project starts with understanding the problem deeply before writing a single line of code.
