Discovery Workshop
This is a very critical phase in the web development lifecycle because it helps us define the project scope and the right web development approach we must adopt. It also helps us predict any challenges likely to crop up during the development lifecycle.
IA & UX/UI Design
Here, we analyze the accumulated insights to develop clickable prototypes, giving you and our web developers a tangible feel of the final product. We refine the app requirements by creating user personas and plan their journey using design mockups to finalize the UI/UX design for web applications.
Development
Selecting the right tech stack is crucial to ensure a robust CI/CD setup. Before we start building the web application architecture, we finalize the web development platform, framework, language, libraries, and APIs. Adopting practices like clean coding and continuous testing further improves the quality of our web development.
Testing
Like other top web development companies, we prioritize QA and testing. Moreover, our web testing procedures are more stringent to ensure a reliable and consistent performance. They include usability, performance, and security testing of critical functions, user interfaces, and additional features.
Deployment
The ultimate goal of all web development programs is to make web applications accessible to all. However, each deployment environment is different. We set up the servers diligently and configure the settings accurately to enable a successful transition from production to live environments.
Support & Maintenance
Web application maintenance and support are integral to enabling user loyalty. Our proficient web developers will continuously monitor user feedback and test your application proactively to minimize downtime and ensure 24X7 seamless performance.
