Engagement Models

Three ways to hire Kotlin developers

Pick the engagement that matches how you actually work. No multi-year contracts — scale up or down month by month.

Dedicated Developer

Most popular

Full-time Kotlin engineer who reports only to you. Best for ongoing products, long-term roadmaps and teams that need a core hire without the HR overhead.

  • 40 hours / week
  • Your Jira, your repo
  • Month-to-month

Hourly / Time & Materials

Pay only for billable hours. Ideal for research spikes, code audits, or variable-load Kotlin work where scope is still being discovered.

  • Weekly timesheets
  • Slack-first comms
  • No minimum commit

Fixed-price Milestones

Scoped delivery with clear milestones and acceptance criteria. Best for well-defined Kotlin builds like an MVP, a migration or a specific module.

  • Scope locked upfront
  • Milestone acceptance
  • Predictable budget
