Experience
Product Cross-reference (Symmetry Surgical, Inc. Through BIS Research)
An internal search tool for cross-referencing competing vendor products to symmetry surgical inventory that included searching for a single product and also in bulk through an input CSV file. This is an ongoing project where I am responsible for UI/UX, development, testing, and deployment of the web app.
In Basket Card View (Epic)
http://www.epic.comA modern UI/UX redesign of the traditional task notification system for all physicians, nurses, and support staff. The project aimed to make the complex task follow-up more intuitive and compact for users. The completion of the project required prototyping, mockup, usability testing, and unit testing. This was a long-term transition involving eight developers (including me) and 1.5 years of development. I was also the point person for release testing strategies and root cause analysis for the entire project to ensure quality before shipping to customers.
Recipient Control Component (Epic)
http://www.epic.comA generic control to enter recipients who would receive the messages sent (like an advanced form of the 'To' box in Gmail). The project aimed to have a reusable organization-level control in all sub-applications for a consistent look and feel. The development included recipient searches and validation of recipients when entered (for patient safety).
Card View Performance Improvement (Epic)
http://www.epic.comI refactored the codebase for the In Basket Card view (20,000–30,000 lines of code were changed) for a more than 50% improvement in performance. Refactoring also involved framework-level changes and strategically loading data only when needed for users.

This included moving to a modern and intuitive UI/UX and a new set of features requested by physicians, such as saving a quick note to a patient's electronic health record. I was the lead developer on the project.
