Description

Backend:

• Built a scalable web service in Go to handle posts and deployed to Google Cloud (GKE) for better scaling
• Utilized ElasticSearch (GCE) to provide geo-location based search functions such that users can search nearby posts within a distance (e.g. 200km)
• Used Google Dataflow to implement a daily dump of posts to BigQuery table for offline analysis
• Aggregated the data at the post level and user level to improve the keyword based spam detection (BigQuery)
• Used Google Cloud ML API and Tensorflow to train a face detection model and integrate with the Go service.

Frontend:

• Built a geo-based social network web application with React JS
• Implemented basic token based registration/login/logout flow with React Router v4 and server-side user authentication with JWT
• Implemented features such as "Create Post", "Nearby Posts As Gallery" and "Nearby Posts In Map" with Ant Design, GeoLocation API and Google Map API
