Role of a Javascript Developer in a Banking Project

Javascript is probably one of the most used programming languages ​​for creating applications and web pages worldwide, so it is not surprising that it is chosen to be used within a software project, including those focused on the banking industry.

A JavaScript developer is of great value to the technical team of a software project since they will have the knowledge to use this language at will and be able to meet the needs of the client and the specific product they are creating, or updating.

The popularity of JavaScript is not something we are inventing, it was proven with a study carried out by Statista, who in 2023 published a list of the most used programming languages, led by the star technology of this blog.

They explained, “In 2022, JavaScript and HTML/CSS were the most used programming languages ​​among software developers around the world: more than 63.6 percent of respondents said they used JavaScript, and only about 53 percent used HTML /CSS”.

What can a JavaScript developer do in a banking project?

A JavaScript developer plays a crucial role in a banking project, contributing significantly to front-end and back-end development processes.

Below is an overview of your responsibilities and duties:

1. Frontend development

• User Interface (UI) Design and Development: Creating and implementing responsive, easy-to-use interfaces using JavaScript frameworks and libraries such as React.js, Angular, or Vue.js.
• API Integration: Ensure seamless front-end integration with backend services via RESTful API or GraphQL.
  Performance optimization: Writing efficient code to ensure that the web application performs well, especially in terms of loading times and responsiveness.
• Security: Implementation of security best practices to protect against common vulnerabilities such as XSS (Cross-Site Scripting) and CSRF (Cross-Site Request Forgery).
• Accessibility: Ensure that the web application is accessible to users with disabilities, complying with standards such as WCAG (Web Content Accessibility Guidelines).

2. Backend development

• Server-Side Logic: Developing server-side logic using Node.js to handle business processes, transactions, and database interactions.
• Database Management: Interface with databases (SQL or NoSQL) to retrieve, update and manage data securely and efficiently.
  Microservices Architecture: Building and maintaining microservices to ensure a scalable and modular back-end infrastructure.
• Authentication and Authorization: Implement secure authentication (OAuth, JWT) and authorization mechanisms to ensure that only authorized users can access certain functionality or data.
• API Development: Creating and maintaining APIs for front-end consumption, ensuring they are secure, efficient, and well-documented.

3. DevOps and deployment

• Continuous Integration/Continuous Deployment (CI/CD): Configure and maintain CI/CD pipelines to automate application testing, building, and deployment.
• Containerization: Using Docker and Kubernetes to contain applications for consistent and reliable deployments.
• Monitoring and Logging: Implement tools to monitor application performance and logging for error tracking and debugging.

4. Collaboration and communication

• Work with cross-functional teams: Collaborate with designers, other developers, product managers, and stakeholders to deliver a cohesive product.
• Code Reviews and Mentoring: Participate in code reviews to ensure code quality and mentor junior developers.
• Agile methodologies: Engage in agile ceremonies such as daily stand-ups, sprint planning, and retrospectives to ensure iterative progress and continuous improvement.

In short, a JavaScript developer in a banking project is responsible for creating and maintaining the application's client-side and server-side aspects, ensuring security, performance, and compliance with industry standards. They work closely with various stakeholders to deliver a robust and easy-to-use banking solution.
