Data Analyst skilled in SQL, Python, and analytics, turning messy data into decision-ready insights.

What I'm looking for

I’m seeking a Data Analyst role to apply strong technical and analytical skills to real business problems—cleaning, querying, and validating data, then translating findings into clear, decision-ready insights for stakeholders.

I’m a Computer Science & Engineering graduate who brings hands-on data work across SQL, Python (Pandas, NumPy), and web analytics. I also have a year of freelance experience evaluating and quality-testing AI outputs on major data-labeling platforms, with a focus on finding failure modes and ensuring correctness.

In my recent roles, I built automated pipelines and reporting that teams could act on. At Thinvent Technologies, I created a Node.js (Express) webhook API to ingest lead data into Zoho CRM on AWS EC2, and I configured Google Analytics and Google Tag Manager for conversion tracking to improve campaign clarity and performance.

I also enjoy turning raw data into clear decisions through analysis and delivery. In my UrbanCart e-commerce project, I cleaned transaction data in Python, wrote 8+ SQL queries (CTEs, window functions) for revenue trends and RFM segmentation, and built a Tableau dashboard that surfaced a festive-season revenue spike to guide inventory and marketing planning.
