 Our team works on the application used for documenting and displaying clinical data. Due to a lot of cross application integration in Epic software, we focus on writing code that is reliable, reusable and easily extendable to support other functionalities.
 Last Documented Value : Used C# and JavaScript to write an API for retrieving the value last documented by a user for a particular type of clinical data that could be displayed to the End users. Focused on writing reliable and reusable code that could retrieve accurate data based on a bunch of input parameter.
 Min/Max Validation: Wrote an API for validating if values entered for a particular type of clinical data respect its configured min/max limits. Worked in C# and Javascript to develop a scalable and maintainable solution using dynamic validation.
 Enhance Table Loading Performance: Worked in C# and cache for improving the time taken by a workflow that loads clinical data and displays it in tabular form. Was able to enhance performance by 40% by retrieving summed up data from the database rather than retrieving raw documented data and summarizing it for display.
