// About the Project
Project Overview
List Assist is a SaaS web app with a list fulfillment system for large-scale data filtering, serving MMI Direct. UppLabs took over after another team failed the project, rebuilt the tech stack, and created a custom filtering algorithm from scratch.
The platform processes tens of millions of records simultaneously, enabling businesses to filter and manage massive marketing datasets with custom parameters. This has been the longest-running UppLabs partnership, active since October 2014.
UppLabs migrated the platform from ASP.NET WebForms to ASP.NET MVC, separated the UI with Angular (currently migrating to React.js), and built SSO authentication, reporting, smart search, and bulk upload infrastructure.
