# Marcos Hung > Software Engineer @ Instagram Location: San Francisco Bay Area, United States Profile: https://flows.cv/marcoshung I've always been passionate about data. The way data can mislead or present itself in a deceptive manner always has intrigued me. For example: In World War 2, the Royal Air Force suffered extensive losses to anti-aircraft fire and wanted to save their pilots' lives by reinforcing their fighters' armor. Their initial approach was to examine the planes that returned from missions and reinforce the areas that suffered the most amount of damage. While this is an obvious approach, it is fundamentally wrong, because if a plane returned safely with significant damage to a certain area, it is most likely not a dangerous area. The best area to place armor would be the areas in which the planes that returned do not have damage to them, because the planes that did suffer damage to those areas never made it back. This is a case in which not having a true random sample in their data caused them to make a rash decision, but thanks to the cleverness of mathematicians and statisticians at the time, saved lives. As I pursue my career in software development I've kept my love of statistics with me, creating projects that utilize statistics and accurate models. My passion for both programming and statistics made it clear for me that big data engineering and data science were perfect for me and I continue to work on projects that utilize large datasets and analytics.

However, after overcoming these struggles through much practice, I developed an even greater sense of understanding of these techniques in order to solve the challenges and problems that I face. I decided to use the knowledge and experience I've gained through coursework and projects to help students beginning in their journey with programming to overcome the struggles that I once faced in their shoes. As a teaching assistant for the Introduction to Data Structures course at SJSU, I helped review and debug 167 students' homework and projects to streamline the grading process. I also helped build the foundation of the class's knowledge of basic data structures and algorithms by explaining and illustrating topics such as Inheritance, Polymorphism, Recursion, Sorting, Stacks, Queues, Linked-Lists, Trees, Maps and overall best coding practices. I ensured that every student got constructive feedback on their code to ensure that their foundation of data structures was exceptional in order to help them succeed in future course work. ### Box Office @ Cinemark Jan 2019 – Jan 2019 | San Jose, California, United States ### Accounting Intern @ AlienVault Jan 2017 – Jan 2018 | United States • Assisted senior accountants by processing data entry and managing vendor transactions and information using NetSuite, advancing work agenda 3 weeks ahead of schedule • Utilized Excel to organize vendor information and operations to reduce workload for senior accountants • Condensed transactions from over 30 vendors to better predict future purchases and managed funds for future financial needs ## Education ### Bachelor of Science - BS in Computer Science San José State University Jan 2018 – Jan 2022 ## Contact & Social - LinkedIn: https://linkedin.com/in/mhung927 --- Source: https://flows.cv/marcoshung JSON Resume: https://flows.cv/marcoshung/resume.json Last updated: 2026-03-22
