This direct line of communication ensures that your feedback is heard and any concerns are promptly addressed, allowing for a smooth and collaborative development process.
Yes, we provide comprehensive post-launch support. After the initial release, we offer maintenance and updates to ensure your product remains functional and up-to-date. Our support services include bug fixes, performance optimization and implementing new features as needed.

We are committed to the long-term success of your project and will be available to assist with any issues or improvements required post-launch.
We specialize in comprehensive custom projects, so a fixed price can only be provided after the conceptualization phase when the requirements are clear. However, we generally prefer to work on a Time and Material basis with weekly time reporting. This ensures the best flexibility, allowing us to adapt to any changes and provide transparent billing for the work completed.
Our team consists of strong mid to senior specialists, ensuring high expertise and smooth collaboration. During the conceptualization phase, you'll work with experienced business analysts, UX/UI designers, illustrators and a product manager. In the development phase, the team includes engineers, QAs and a project manager. We provide a full cycle of services from ideation to development and post-launch support, ensuring well-coordinated communication throughout the project. The final team composition is tailored to your project's specific needs, considering technologies, environment, and scope.
To kick off the project, we need the following from you: 1. A clear vision and goals for your project. 2. Any existing documentation or materials related to your project. 3. Key requirements and features you want to include. 4. Your target audience and any market research data. 5. Regular communication and feedback to ensure alignment. Providing this information helps us understand your needs and ensures a smooth start to the project. If you don't have all this information, don't worry, we will help you to elaborate it during the discovery phase.
Our approach to QA (Quality Assurance) and QC (Quality Control) is thorough and systematic to ensure the highest quality product. Here's how we do it: 1. Requirement Analysis: Understanding and documenting your requirements clearly. 2. Test Planning: Developing detailed test plans covering all aspects of the project. 3. Continuous Testing: Implementing automated and manual testing throughout the development process. 4. Bug Tracking: Using robust tools to track and manage any issues. 5. Feedback Loop: Regularly reviewing test results and incorporating feedback for improvements. 6. Final Review: Conducting a comprehensive final QA check before release. This rigorous process ensures a high-quality, reliable, and user-friendly product.
We take the confidentiality and security of your project very seriously. Our measures include: 1. Non-Disclosure Agreements (NDAs): We sign NDAs to ensure your information is protected. 2. Secure Communication Channels: We use encrypted communication tools for all project-related discussions. 3. Access Control: Only authorized team members have access to your project data. These steps ensure that your project remains confidential and secure throughout the development process.
