What I'm looking for

I’m looking for a role where I can own ML data operations, build automated Python/SQL pipelines, and use statistical modeling to improve SLA performance, data quality, and delivery. I want teams that value proactive planning and operational impact.

I’m a Data Scientist with a Master of Science in Data Science and 4+ years of experience supporting machine learning pipelines, predictive modeling, and data engineering for real-world decision systems. I’ve managed end-to-end ML data operations at scale, delivering 4.6M+ labeled data points to production models.

I build automated Python/SQL pipelines that turn messy, distributed sources into reliable reporting and operational insights. By consolidating Hive data into weekly underdelivery and quality reports, I reduced manual preparation time by 88%, and I improved visibility by removing data lag in SLA dashboards.

I also focus on quality and reliability: I’ve automated Root Cause Analysis pipelines, performed statistical QA and arbitration across cases, and supported SLA tracking and escalation with data-driven backlog forecasting. I’m comfortable deploying end-to-end data solutions on AWS and turning analytics into actionable workflows.
