What I'm looking for

I seek a role that leverages data analysis and process optimization in a collaborative, impact-driven environment with opportunities for technical growth and cross-functional work.

I am a physics graduate with four years of hands-on experience in data analysis, visualization, and process optimization using Python, MATLAB, PostgreSQL, and Excel.

I led and collaborated on a data-driven process optimization project at a DOST-incubated startup, achieving an 89.59% increase in adsorption efficiency through experimental design, data cleaning, regression modeling, and validation with FTIR and SEM.

I have built end-to-end analytics pipelines, designed PostgreSQL databases with advanced SQL (CTEs, joins, window functions), and translated complex results into dashboards and executive summaries using Excel and Git for reproducible reporting.

I am detail-oriented, comfortable in deadline-driven environments, and motivated to solve practical data problems with rigorous analytical methods, strong technical writing, and cross-functional collaboration.
