As a Sydney PHP development service provider, we understand your app idea, and its market potential defines your app’s value and creates a high-level user flow design, among other things. This session also lays the groundwork for your project’s development pathway, branding assessment and marketing strategies.
We break down the project into user stories that capture your needs and goals clearly. This simplifies the project into smaller and more manageable pieces of work during the AGILE development process. It ensures we prioritise the requirements and complete the work efficiently.
After understanding your vision, we create a wireframe that outlines the structure and flow. Once these are approved by the client, we move on to the development phase.
Based on your project, we select the perfect technology stack taking into consideration your app’s complexity, functionalities and budget. We then plan multiple sprints over an AGILE development cycle to make sure the final product is satisfactory and delivered efficiently.
Throughout development, we conduct testing, including UI/UX, security assessments, and performance evaluations, to ensure your app is reliable, secure, and high-quality.
We provide a testing environment that closely resembles the final product for your approval. UAT helps confirm that the app meets your expectations and prepares for the next development phases.
After the UAT is completed successfully, we organise the live process and deploy your app into the production environment and submit it to the app store.
We offer a one-month warranty to monitor your app’s performance and address any emerging issues. Our goal is to ensure a smooth launch and resolve any initial problems promptly.
After the post-live support, we offer various service level agreements (SLAs) that can be adjusted to your specific needs. We also provide different maintenance packages, which will keep your app up to date.
