Experience

Survey Analytics Portal

A survey analytics web portal built with Django REST Framework, PostgreSQL, and React. The web portal creates, distributes, and collects survey responses and analyzes the results. As a back-end developer, I provided RESTful API endpoints, refactored the existing codebase to improve performance, and created efficient reports that were scalable for the number of surveys and respondents.

Part Tracking and Traceability

PTT was a web application built with Spring Framework and AngularJS. It collected information on smart meter parts before and during assembly, validated smart meter boards based on tests done before assembly, and was used to trace root causes of issues logged by customers.

Compare GitHub Profiles
