Postman: Building Trusted Government Communication

Before Postman, government agencies relied on more than 500 different SMS sender IDs to contact citizens. This fragmentation created confusion, made impersonation easier for scammers, and caused important government updates to be ignored. Postman was created to solve this challenge by consolidating communication under a secure, unified, and trusted channel that only government agencies can use.

I led a team of designers and engineers to build Postman from 0 to 1 for its first version, and scaled it to more than 100 agencies. The platform supported MOH and MCIS in COVID-19 communications and was instrumental in powering the Homer COVID home quarantine operations.
