FAQs

Hiring Kotlin developers — answered.

What does it cost to hire a Kotlin developer?+

Rates depend on seniority and engagement model. Most Kotlin developers start from £350/day for mid-level and £550/day for senior, with discounts on longer engagements.

How fast can I get a Kotlin developer onboarded?+

We typically shortlist within 48 hours. Most Kotlin developers can start within 5–7 working days from sign-off.

Can I scale my Kotlin team up or down?+

Yes. Engagements are flexible — add a developer next sprint, or scale down after a launch. Notice periods are short and transparent.

Do you handle the full project or just supply developers?+

Both. We do fully managed delivery (PM, design, QA, devops, Kotlin engineering) or supply individual Kotlin developers to your team.
