Junior Data Analyst who cleans messy data, builds useful dashboards, and automates reliable workflows.
United StatesWhat I'm looking for
I’m a Junior Data Analyst who enjoys cleaning up messy systems and making them run more efficiently. My experience blends data, operations, and staying organized behind the scenes, with a strong focus on reliable workflows that help teams move faster without unnecessary friction.
In my current role, I support enterprise data governance initiatives using Reltio MDM, including cleaning and merging over 80,000 duplicate records to improve data accuracy and operational efficiency. I also help automate manual data workflows, contributing to a 15% improvement in construction site operations, while developing SOP documentation and testing integrations with tools like Postman, REST APIs, Zephyr, and Jira. Earlier, I improved employee onboarding efficiency by 44% through Active Directory process optimization, built pipelines with Amazon S3/AWS Glue/Athena (cutting data processing costs by up to 90%), and created automated dashboards that saved about 5 hours per week—all while conducting regression/statistical analysis to support merchandising strategies and tracking KPIs like MRR.
