    Frequently Asked Questions

    How do you decide whether to build web and mobile together or separately?

    We evaluate product scope, release priorities, and backend complexity. In many cases, a shared architecture reduces duplication while still allowing platform-specific optimization where needed.

    Early clarity on requirements and feedback loops is most helpful. After that, we operate independently while keeping stakeholders aligned through regular technical and product check-ins.

    We design for growth upfront, but also plan for post-launch tuning. Performance bottlenecks are monitored and addressed incrementally, not through disruptive rewrites.

    Yes. We frequently take over or extend existing codebases, assess architectural gaps, and stabilize or improve systems without forcing full rebuilds.
