I am Chang, currently pursuing a Master's degree at HEC Paris. Being an experienced campus ambassador at HEC Paris, I have an in-depth understanding of the application processes for business schools. I can bring both a business perspective as a management student, as well as an academic perspective as an engineering student, into your essay. I will work to make sure that your resumes and essays are creative, professional, and precise. I can help with: - Polishing business school application materials (Essays, CV, RL, etc.) - Web Scraping - Web development - Data Engineering with Spark/Hive - Data Analytics with R/Python/VBA - Data Visualization with Tableau/PowerBI/Neo4j
