Digital Address Verification (DAV)

During the COVID period, physical address verification became difficult as in-person visits were restricted. To ensure that address verification could continue without delays, OnGrid introduced Digital Address Verification (DAV).

DAV was designed as a Progressive Web App (PWA), where candidates receive a secure verification link via SMS. The link opens directly in the mobile browser, allowing users to complete the verification process without installing any application.

The goal was to create a verification experience that works reliably across:

• Different phone types
• Varying internet quality
• Users with limited digital familiarity

Moving address verification to a web-based experience introduced several challenges:

I worked as the sole designer, collaborating with a product manager and two developers. I was responsible for:

• Designing the end-to-end verification experience
• Structuring the PWA flow
• Making camera and permission interactions understandable
• Designing for accessibility and low-bandwidth conditions

Designing DAV as a Progressive Web App highlighted how interaction design choices become even more critical when technical affordances are limited.

Since users are operating inside a browser:

• Trust must be earned quickly
• Instructions must be extremely clear
• Errors must be prevented, not explained later

This project reinforced my interest in Human–Computer Interaction, particularly in designing for accessibility, trust, and real-world constraints.
