JOSEPHINE WIJAYA
DATA ANALYST & DEVELOPER • HP 100/100
→ ABOUT ME
Greetings, player! I'm a curious Business Analyst turned Data Enthusiast with a Civil Engineering background. I love gaming (hence the retro theme!) and bring that strategic mindset to data analysis. I code in Python and R for statistical analysis, build React apps with AI assistance (thanks Claude!), and transform complex data into actionable insights. I've researched 100+ public companies for $5M+ investment decisions across North America, Asia, and Europe, and achieved 60% cost efficiency in hiring process optimization. From financial audits to trading validators and ML models, I'm always leveling up and exploring new tech!
