Digital Identity Application for Arizona State University

A digital identity application (an e-wallet or educational wallet) for ASU. As a DevOps engineer, I handled the whole application infrastructure on AWS across four environments using Terraform, the release processes with CI/CD pipelines using AWS CodeBuild and CodePipeline, and building customized webhooks for notifications/alerts. The team consisted of 17 colleagues across four teams, where I mainly worked with two other DevOps engineers in the DevOps team.

Document Search Engine

Set up an Elasticsearch cluster and configured its shards. I uploaded over 200,000 Word, PDF, and TXT documents and made them searchable through the cluster. Users could search for documents from a decade back in just milliseconds.

Monitoring Solution for a DBaaS

Customized a monitoring solution for a SaaS product offering analytics databases as a service.
