Leveler.com, a fast-growing SaaS platform for independent contractors, migrated its database from Couchbase to MongoDB, resulting in 30x higher performance and 3x lower development overhead. The company implemented a multi-tenant environment, using MongoDB's expressive query language, consistent indexes, and powerful analytics via the aggregation pipeline to improve query performance and reduce development time. After migrating, Leveler.com achieved major application performance gains, reduced storage needs by 40%, and freed up its development team from spending 50% of their time on database-related development, allowing them to focus on building application functionality that drives business growth.
