Our Work

  • The largest retailer in the world relies on Formidable to build their mission critical application infrastructure. We've also built significant portions of Walmart's mobile website and maintain their in-house framework Thorax.

  • We provide training for Ookla's developers and have helped design and develop NetIndex. We are broadly assisting their efforts to migrate other applications away from Flash.

  • We crafted the two month long Code Fellows JavaScript Bootcamp curriculum from the ground up. Our work ensures that students have a solid grasp of the language fundamentals and advanced features in a rapidly changing development ecosystem.

  • MuleSoft connects the APIs of big business. We designed and built the API Notebook for MuleSoft, an online editor that allows developers to create interactive tutorials and explore use cases for APIs based on MuleSoft's RAML format.

  • Backbone Testing

    We wrote the book on Backbone.js Testing, a guide that brings sensible practices and modern techniques to the traditionally tedious world of frontend application testing. We provide an open source online compendium of examples and testing resources.
