Business Engagement

We at Callistofusion tailor the software development process to your specific business needs to deliver high-quality software on time and within budget.

Development Approach



The Agile methodology allows us to release reliable software fast and introduce changes easily. The development process consists of 1–4 weeks iterations resulting in an evolved version of software shipped each time. After each iteration, we get real user feedback that drives informed decisions on the next development steps.

Note: Although the Agile approach is viable in many cases, we can also adopt Waterfall and other approaches depending on a customer’s objectives.



With an established DevOps culture, we streamline software delivery and improve its quality with the following DevOps best practices:

Continuous Integration/Continuous Delivery or Continuous Deployment (CI/CD): automating integration and deployment of code changes.

Infrastructure as Code (IaC): automating the creation of new infrastructures and keeping them consistent with each other to ensure smooth software deployment.

Automated testing: automating regression, performance, and other types of testing that are continuously carried out within the CI/CD pipeline.

Application performance monitoring: configuring application performance monitoring tools to detect post-release bugs quickly.

Cloud-native development

When building applications in the cloud, we take advantage of reduced software development and operation costs, easy scalability and access to advanced cloud services that enable implementation of cutting-edge techs (AI, IoT, data science, and more).

Development Process


1. Business Analysis

Our business analytics extract information about your business needs, turn them into prioritized software requirements and help elaborate on the concept of your software.


2. Software development process and management

In every project, we design UX and UI, build a future-proof architecture as well as run coding, integration and deployment processes. We take care of the overall project management and regularly report to you on the development progress.

3. QA & Testing 

We keep up software quality with continuous testing, starting from unit tests and code reviews done by the developers to functionality, performance, usability, integration, compatibility and security testing by our QA team. A reasonable amount of test automation helps us speed up software delivery and minimize the number of missed bugs.


4. Risk Management 

We define and estimate risks related to the project budget, delivery time, cybersecurity, new technologies and personnel. Then, we prepare a mitigation plan for each risk, monitor risks and report to responsible project stakeholders to keep all parties informed about existing risks and their states and ensure the consistency of risk management actions.


5. Change Management

We review the required software changes with all parties concerned, analyzing how the changes will impact software business logic and adapting it accordingly before any change implementation.


6. Project Delivery

Upon the delivery of the project, our customers receive:

  • Turn-key software

  • Documentation (technical requirements and design)

  • User manual

  • Setup program

  • Installation and maintenance instructions

  • Source code

  • Warranty

Our customers retain full intellectual property rights over software.

Upon software completion, we offer maintenance and support services to help continuously improve software.


Benefits of Cooperation


We plan our work in a way to deliver the specified scope on time and are capable of working with tight schedules.

Self-management by objectives

We minimize management efforts on the customer’s side while providing a high level of transparency over the development process and proactive risk management.

Effective collaboration approaches

We welcome real-time and individually paced communication models.
