    I am an enthusiastic back end .NET developer. I have deep experience with C#, SQL, API's, cloud technologies (AWS and Azure), and much more since 2016. I am fairly new to the UpWork platform, and most recently worked for Moody's Analytics for the past 4 years. I loved my time there, but wanted to pursue some personal projects and a more active lifestyle. In my spare time I enjoy rock climbing and remodeling my house :) One project I am especially proud of is developing an original search algorithm similar to Zillow Zestimate. I greatly improved the accuracy of the results from the old algorithm by using complex mathematical formulas, and reduced the query time from 20+ seconds to a small fraction of a second. Another fun project was running risk analysis calculations for investment portfolios, which required 100k to 2mm service bus messages and calculations per request. To achieve this in real-time, my team and I engineered a microservice structure with Azure Functions that scaled on demand. We were extremely detail oriented with our code and the settings in Azure to make sure everything ran quickly and with minimal cost.
