Insurance Claim Management Application

PROJECT: A claims management system for an insurance company.

I managed three developers working in several time zones while collaborating with a business partner who did the requirements gathering. Midway through development, the system was handling ~1,500 claims per day. I spent about 75% of my time working on database performance and implementing new features. I spent about 25% of my time managing requirements, timelines, the team, and interacting with my business counterparts.

We released features weekly and dealt with requirements that changed very frequently.

Trucking Business Management Tool

PROJECT: A web-based schedule management tool for the office staff of a trucking company.

First, I created a project roadmap based on the business requirements and collaborated with business counterparts to ensure all business level requirements would be met. Later, I developed a mobile app that displayed schedule information and collected project details from the truck drivers. The app also had to be effective during offline mode for several days.

After our initial "beta" version was rolled out, I performed more detailed user interviews to refine the product. Now I'm maintaining the application, which includes fixing small bugs and building minor features.
