What I'm looking for

I’m looking for a Junior Data Analyst role where I can build reliable SQL-driven dashboards, automate reporting, and maintain clear data documentation—so teams can spot anomalies, track KPIs, and make better day-to-day decisions.

I’m a Junior Data Analyst focused on turning messy, operational data into trustworthy dashboards and repeatable reporting views. I bring hands-on experience with SQL, Python, and BI dashboards, plus a strong data QA mindset for KPI investigation, anomaly analysis, and clear data definitions.

In technical operations, I built and maintained operational dashboards and reporting views using SQL, Python (Pandas), Power BI, Looker Studio, Tableau, Excel, and SQLite—helping teams monitor capacity, workflow status, delivery risks, and KPI trends across multiple accounts. I also pulled, cleaned, and QAed data from workflow sources, converting recurring stakeholder questions into self-service reporting and concise, action-oriented updates.

Before moving deeper into analytics, I supported regulated lab and pharmaceutical environments through LIMS implementation and maintenance and rigorous process documentation. That background shaped how I work: I prioritize validation checks, user guidance, and documentation so stakeholders can trust system records and reporting outputs.
