Frequently Asked Questions
Clear answers for a confident start.
Everything you need to know about our process, communication, ownership, and delivery timelines.
Yes. Many of our collaborations begin with an initial concept or problem statement. During our initial Discovery phase, we work with you to analyze target users, outline functional user stories, define a Minimum Viable Product (MVP) scope, and create interactive UI prototypes before writing production code.
Absolutely. We regularly audit and modernize pre-existing codebases. We can refactor legacy components, upgrade deprecated dependencies, optimize database query performance, patch security vulnerabilities, or add new feature modules to your current tech stack.
Following an introductory project discussion, we break your requirements into modular sprint components with explicit deliverables. We provide transparent estimates with milestones rather than arbitrary figures. All financial and schedule agreements are documented and approved in a project scope agreement prior to commencing work.
All communication is conducted in clear, professional English. We use your preferred collaboration tools (Slack, Microsoft Teams, Google Meet, or email) alongside project boards like GitHub Projects or Linear. You receive structured written weekly progress reports and regular live staging previews.
You do. Upon completion of milestone deliverables and payment, 100% of the custom source code, documentation, assets, and repository rights belong exclusively to your business. We never hold your code hostage or restrict your ability to transfer it to an in-house team.
Yes. We offer flexible post-launch support and maintenance packages. These can include ongoing application monitoring, security patches, library upgrades, bug resolution, and dedicated development hours for iterative feature enhancements as your user base expands.
