Purpose
As a software engineer, I passionately problem-solve with creativity and empathy in Full Stack software development
roles, with skills like React, Redux, JavaScript, Node, Python, Flask, Sequelize, SQLAlchemy, PostgreSQL, and Docker.
These skills are on full display in website projects I built solo and in team settings that mimic features of popular websites.
My coding is fueled by my curiosity, teamwork, and discipline built through my academic pursuits in business administration, economics, mathematics, and finance.
I learned to pick up new tech skills quickly during my digital content career, designing full-page magazine ads, travelling globally for photography, and editing marketing videos.
In sum, I continuously learn new tools and concepts to build solutions in software development to better the world.
