Nibble

Key Technologies:

AWS Serverless Docker Python Terraform

Company Intro:

Nibble is a startup offering an innovative bot-based price negotiator as an alternative to discount codes.

Team Composition & My Role:

My role was as the sole DevOps engineer to setup the configuration and work with the CTO to coordinate code changes and deployment timings.

Project Details:

I was tasked with looking at the existing Nibble setup and:

  1. make recommendations for best practice in terms of their infrastructure and security
  2. ensure their api was able to handle high volume traffic.

After analysis, I recommended migrating to using the Serverless framework for their Lambda api and start using Terraform for their AWS infrastructure. I implemented the configuration for this along with scripts to easily deploy the configuration on a per environment basis. As part of the migration, I also migrated their production database to Aurora Serverless for improved scalability.

For volume testing, I setup a JMeter script to simulate their expected client patterns which included dropoff and several different client flows. While load testing, I found limitiations with AWS Lex and their transaction per second (TPS) limit and worked with AWS to increase the TPS limit for the Nibble account.
