FAQ

What is custom development?

It’s the process of building a web or mobile app designed around your specific needs. Unlike off-the-shelf tools, it’s built for your users, workflows, and business goals.

We create business web apps, e-commerce platforms, iOS/Android apps, internal tools, and data/AI projects.

Timelines depend on scope and complexity. An MVP takes 3–6 months; a full solution requires more time. We deliver in Agile mode to provide usable versions quickly.

Contact us to get an estimate for your project.

We work with your tools (Slack, Teams, Jira, Trello) and set regular meetings to maintain transparency and efficiency.

We adapt the stack to each project: JavaScript, PHP, .NET, Java, Python, React, Angular, Vue.js, Symfony, Laravel, plus DevOps and cloud tools (Docker, AWS, CI/CD).

Yes. Our Agile/Scrum approach allows you to change priorities or features at each sprint.

Systematic code reviews, automated tests, QA validation, and senior oversight ensure maintainability and robustness.

We can add specialists (QA, DevOps, Data, etc.) to the team at any time.

All projects are covered by NDAs. We apply strong security practices: authentication, encryption, access control, and monitoring.

They depend on team composition, seniority, and project duration. We provide transparent, detailed estimates and budget tracking.
