As a project requirement, I built the infrastructure and script to do performance testing for Reaction with my Team Lead. More about that can be found here: https://blog.reactioncommerce.com/performance-and-load-testing/

1. Maintaining and creating APIs for the website's Node.js server from scratch.

2. Implemented a server that handles all the image upload/download from the website. The performance was optimized to 12x of the original. The server is running on GAE(Python).

3. Optimized and improved search relevance for the site. Improved DCG from 0.4 to 0.68. Mostly optimizations were made to ElasticSearch. For this search data was collected(in BigQuery) and then analyzed.

4. Migrated the infrastructure and MongoDB from AWS to GCP without downtime.
