A Success Story: Pulsion’s Collaboration With Accourt

Our collaboration with Accourt allowed us to spearhead a revolutionary project to replace a legacy Fraud Management System for a major UK financial institution. The initial SharePoint-based solution severely lacked reporting capabilities, had no scalability, and faced user-friendly challenges regarding the user interface. Ultimately, we proposed a solution by migrating the system to a fully serverless Amazon Web Services (AWS) solution with highly-resilient, scalable, and cost-effective benefits.

The serverless architecture from AWS delivered lower software infrastructure costs and abolished maintenance concerns. The serverless setup ensured scalability and enhanced reliability across all the necessary availability zones Accourt needed. The financial institution has over 2,000 users and 20,000 transactions monthly. However, our new solution surpassed independent audits and exemplified Pulsion’s commitment to high-quality delivery in every system. Accourt Managing Partner, Vaughan Collie, hailed the outcome, praising the system’s performance and durability.

Capabilities and Limitations FAQs

JavaScript application development agencies can provide web and mobile app development with the programming language and appropriate resources. Our dedicated team can deliver exceptional mobile app development projects using a JavaScript framework like React Native or Ionic. The versatile language can do more than web application development to boost your digital presence.

You could hire Android app developers for Android app development, or use our React Native app development services for JavaScript experts proficient in using frameworks like React. Alternatively, try our mobile app development company or custom iOS app development company services, both of which can use custom JavaScript development.

JavaScript development companies are limited as the programming language isn’t good for heavy-duty desktop app development, direct database manipulation, the compilation of other technologies, complex server-side logic, concurrency, parallelism, real-time data systems, high-performance computing, and system-level programming. Contact us to discuss whether your project requires any of the above elements that would exclude JavaScript in software solutions.

Usage and Ecosystem FAQs

The JavaScript programming language is primarily used for the back-end and front-end development necessary for interactive websites, application development, and mobile applications, whereas the HTML-CSS combo is used for structure and style in web development. The HTML-CSS combination can’t produce interactive features and elements to engage users as much as JavaScript.

The JavaScript scripting language is primarily used to create a vast array of dynamic content in software applications, game development, operating systems, JavaScript software, web browsers, mobile application development, applications with web servers, and sophisticated web applications. JavaScript applications use advanced tools in extensive libraries for the ultimate user experience.

A vast array of JavaScript libraries exist for web development, including back-end development libraries like React JS, Vue.js, Angular, and jQuery. Some front-end libraries from JavaScript include Node JS, Express JS, Nest JS, Sail.js, and Meteor.js to develop apps for a desktop or web server device.

The vast array of libraries available from JavaScript makes it ideal for full-stack developers to provide rich JavaScript applications with sufficient JavaScript files in rapid development processes. Contact us to discuss which frameworks and libraries work better to create successful projects for your business.
