JavaScript Development Company Hiring Guide

What is a JavaScript development company?

Hiring JS development services ensures that a business’ website, software, or application has a modernized user interface and provides a seamless user experience. By partnering with a reputable JavaScript development company, businesses can unlock the full potential of their online presence, enhance user satisfaction, and drive growth.

The car company needed a partner to transform its internal tools to optimize workflows and make the app easy to navigate for users.
  • Solution: Cheesecake Labs helped FINN’s existing engineering team automate its processes. It also modernized its back end and internal tools by adding key features in its customer portal, allowing users and team members to easily and efficiently perform tasks like ordering or making account changes. Using Node.js, Typescript, and a PostgreSQL database, Cheesecake Labs transformed FINN’s US operations.
  • Results: The partnership resulted in an over 1,200+ increase in subscription for FINN. The internal tools built by Cheesecake Labs also generated significant usage, with a boost of 6,000+ page views per month.
