Designed a full stack project using Flask and React to improve the UI of multiple Jenkins jobs

Improved an existing workflow by saving up to 50% execution time using AWS EBS Snapshot and AWS S3

Set up servers in different colocations in C++ to fetch registers’ values from FPGAs through UDP and send them to the backend through TCP (protocols defined by Protobuf), handling potential failure exceptions

Set up Flask backend in Python to fetch colocations’ info from Redis, retrieve registers’ values from different servers through TCP (Protobuf), and send them to the frontend, handling potential exceptions as well

Set up React frontend in Javascript/CSS/HTML to display registers’ values of FPGAs in colocations, with key bindings, graphs and color changes, using Redux as state management, handling exceptions and alerts

Redesigned an on-call scheduler with a greedy algorithm considering folks’ last on-call date, percentage of free time during an on-call slot, calculated by fetching events from google calendar in Python

Enabled integration of the on-call scheduler with Slack, e.g., post on-call information in channel, update users of on-call user group, update on-call topic of the channel, and alert if anyone hasn’t been on-call for a long time

Created modules like DatapathAPIModule to access data from other services and refactored some common codes

Created templates to set up VPC endpoints, hosted zones and security groups

Implemented ASIN Parent Validation to check if the ASIN is parent and created integration tests in Java

Implemented Deal Stacking Validation to detect any promotions stacking with each other unintentionally in Java
