Meta | Software Engineer Intern

1. Implemented both the back-end and front-end of an Ads unit for Instagram feed using Hack and Python, which can potentially reach 5M users daily, aiming to drive up revenue.
2. Ran multiple A/B experiments and wrote SQL queries to analyze data provided by over 1M daily reached users, including exposure, revenue, CTR, etc.
3. Extended logging functions for all Ads units in Instagram Reels, providing more analytical logging data without taking up too much database storage.
4. Migrated the front-end of several Facebook Ads units to a new internal framework, harnessing more compatibility and consistency without any change in user experience

Proposed a new scalable spatio-temporal graph network model EGSN which adopts a relatively less explored model evolution method and incorporates the inspiring message-passing, sampling and aggregation mechanisms from static graph methods. It's also combined with an RNN structure to adjust weights over time. The experiment results showed some significant improvements comparing to the baseline methods in some situations.
