What I'm looking for

I seek an entry-level role applying geophysics and data analysis (Excel, Python, Tableau), working in collaborative teams, contributing to modeling and field projects, and growing into technical responsibilities.

I am a geophysical engineering graduate and data analytics professional who converts complex datasets into clear, actionable insights. I processed and modeled 382 data points with <1% average error, built two 2.5D subsurface models, and integrated gravity, seismic, and spatial datasets to improve subsurface interpretations.

Proficient with Microsoft Excel (Pivot Tables, lookups, dashboards), MATLAB, basic Python (NumPy, Matplotlib), and basic Tableau, I pair analytical rigor with practical field experience from internships and coordinating gravity surveys. I also promoted priority fund products as a telemarketing freelancer, acquiring 28 valid customers within 2 months, demonstrating data-driven communication and client relationship skills.
