Maddie Stigler is a professional developer for a consulting firm based
in Richmond, Virginia. She is a part of the core team for Women Who
Code in Richmond and is involved in many local Microsoft and Amazon
meetups. Her interest in cloud computing began while studying computer
science at the University of Virginia and has only grown since then.
Maddie has maintained a fascination with serverless technology from the
start and has applied principles of serverless design and architecture both
in her professional and personal work, including developing a flight status
service for travel insurance customers using AWS Lambda and Node.js.
Her favorite application to date has been creating Amazon Alexa skills by
utilizing Lambda functions written in Node.js and triggering them with the
Alexa Skills Kit. Maddie plans to continue pursuing her interest in growing
cloud technologies and serverless architecture and share her knowledge
so that others can do the same.
