Overview

A local engineering firm needed a live bidding system that could replace email attachments and shared folders. I built authenticated workflows for submitting and reviewing bids, cloud storage for application documents, and encryption for sensitive business information in the database.

Outcomes

  • Live bidding workflow for a local firm
  • User authentication around bid submission and review
  • Cloud storage for application documents
  • Encrypted storage for sensitive business information
