Software Development Process

  • Frontend Design and Development

    User Interfaces are created with the knowledge of UX Design and Psychology, using graphic design software and prototyping tools like Figma, Adobe Xd, and Photoshop.

    Frontend or client-side applications are mainly developed with HTML, CSS, JavaScript. In many cases using web technologies, libraries, and frameworks like Bootstrap, jQuery, React, Angular, etc. are preferred depending on the time, scope, and complexity of each project.

  • Backend, API, and Database Implementation

    Backend or server-side applications and APIs are implemented with Java, Python, PHP, NodeJS, and frameworks like Ruby on Rails and Express.

    In case of the need for relational database SQL and MySQL, and for non-relational or NoSQL database cross-platform document-oriented database programs like MongoDB may be a relevant option based on the scope of projects, authentication options, data structures, and human-data interactions.

  • Web Development Process

    There are several steps in web application design and development process. Although this process may vary slightly from designer to designer, the basics principles are the same and include:

    • Requirements Analysis
    • Architecture & Design
    • Implementation (Coding)
    • Testing & Debugging
    • Deployment & Maintenance
