Freelancer Overview

Software engineer with 5 years of experience working with large-scale structured datasets at Amazon and in my own projects. While my background is in engineering, much of my work has involved tasks that map directly to data labeling: designing classification schemas, validating data quality across hundreds of thousands of records, investigating edge cases and labeling inconsistencies, and building pipelines that surface clean signals from noisy data. At Amazon, I resolved a pagination bug that was silently truncating 200,000 records, built an enrichment pipeline reconciling HR hierarchy data across 30,000+ entries, and diagnosed a false-success error pipeline. All of this required precision, consistency, and careful attention to data boundaries. I also designed an in-house risk classification service for my startup BillingBase, where I built and tuned heuristics for transaction risk scoring, AML screening, and fraud detection without third-party tools. This required defining clear labeling rules and handling ambiguous cases at the edges. My technical background lets me work directly with raw datasets, understand the downstream impact of labeling decisions, and maintain consistency across high-volume workflows. I'm a fast learner who takes quality seriously and holds myself to a high standard on repetitive, detail-oriented work.
