Conducted code and design reviews.• Lead initiatives in the areas of research and development.• Designed and developed full stack and back-end software services in collaboration with teammates. Primarily using SQL Server, C#, TypeScript, and Angular.• Created a technique called non-naïve quadrant analysis using NLP and unsupervised learning. This was used to automate decision making for healthcare system leaders. This was primarily done using R for proof of concept, and C# for enterprise implementation.• Performance tuned the backend of an enterprise analytics engine for improved MTTR and MTBI metrics. Lead to a 100x improvement in MTTR. Show less
