What I'm looking for

I’m looking for a Data Analyst role where I can build KPI dashboards in Power BI, automate reporting with AI workflow integration, and support operational decision-making using clean, reliable data.

I’m a results-driven Data Analyst with hands-on experience supporting data collection, cleaning, analysis, and reporting in Oil & Gas and fast-paced operational environments. I use SQL, Python (Pandas, NumPy), and advanced Excel capabilities to validate data accuracy, uncover trends in operational datasets, and translate findings into stakeholder-ready outputs.

In my recent roles, I built and maintained interactive Power BI dashboards and KPI reports, wrote optimized SQL queries for analysis and reporting, and produced clear visualizations using Python (Matplotlib/Seaborn) and Excel charts. I also bring LNG-adjacent project exposure and a focus on automating workflow and improving output quality through AI Task Management & Integration, so decisions are faster, clearer, and more reliable.
