dotHow It Works

What a Kotlin Developer Can Do for You.

Kotlin covers more ground than most hiring managers expect. Native Android, shared cross-platform code, server-side services, and modern UI development all fall within its scope. Here is what that means for your product.

Android App Development

Kotlin is Google's language of choice for Android, and our experts use it to build fast, polished native apps that simply feel right. Healthcare apps, fintech tools, travel booking clients, and retail experiences all benefit from the performance and reliability of native development.

Guide icon

UI Development

Jetpack Compose is the modern way to build Android interfaces; it replaces XML with clean, declarative Kotlin code. Our experienced developers use it to build UIs that are faster to iterate on, easier to maintain, and better suited to polished products that users in ecommerce and SaaS expect.

Kotlin Multiplatform

For businesses that want true native quality on both Android and iOS platforms without maintaining two entirely separate codebases, Kotlin Multiplatform is a perfect middle ground that 2am.tech's experienced engineers know how to use well.

Smooth App Experiences

Nobody wants an app that freezes while being used. Our developers will make sure yours handles multiple things at once smoothly. Keep the experience fast and fluid whether users are tracking a delivery, bidding on an auction, or sending messages in real time.

Guide icon

Backend Development

Kotlin works on the server too. Ktor is a lightweight Kotlin framework for building backend services and APIs, favored by teams that want a consistent language across their Android and server layers. RolesPilot's Kotlin developers with Ktor experience are available part-time, full-time, or on an hourly basis.

Java to Kotlin Migration

If your Android app has been around for a few years, chances are it's been built in Java and needs a technical refresh. Let our experts keep everything live and stable while gradually bringing the codebase up to modern standards.

dotFAQ

Common questions about hiring Kotlin Developers.

How quickly can I hire a Kotlin expert through RolesPilot?

Most companies receive their first qualified matches within a couple of working days. Once you select a candidate, onboarding and project kickoff can usually happen within the next week. RolesPilot handles sourcing, vetting, contracting, and coordination, which removes the delays commonly associated with traditional recruitment. Whether you need one specialist or multiple team members, the platform is built to help companies scale quickly without compromising on quality, communication, or technical expertise throughout the hiring process.

What makes RolesPilot different from Toptal or Upwork?

RolesPilot combines expert-led vetting with hands-on hiring support, and gives companies a more reliable and structured hiring experience. Every professional is reviewed through technical assessments, communication evaluations, and live interviews conducted by senior specialists. Unlike open freelance marketplaces, RolesPilot focuses on long-term business partnerships, carefully matched recommendations, and ongoing support throughout the engagement. Companies also avoid the operational complexity of international hiring, since RolesPilot manages contracts, payments, and talent coordination through a single U.S.-based partner.

Are your Kotlin developers aligned with US timezones?

Yes. RolesPilot works with professionals across Latin America, Europe, North America, and other locations across the globe, allowing companies to hire talent with significant overlap with U.S. business hours. Many experts already work with American companies and are experienced in remote collaboration, agile delivery, and daily communication across distributed teams. If your project requires a specific timezone alignment or schedule, RolesPilot can source talent accordingly. This makes it easier to maintain real-time collaboration, faster feedback cycles, and smoother integration with your internal team

What engagement models are available? Full-time, part-time or staff augmentation?

RolesPilot supports flexible engagement models based on your business goals, delivery timelines, and internal team structure. Companies can hire talent full-time, part-time, hourly, or as part of a larger staff augmentation initiative. Whether you need a single specialist for a short-term project or an extended remote team to support long-term growth, the platform adapts to your hiring needs. RolesPilot also manages the administrative and contractual side of the engagement to help companies scale without additional operational overhead.

What if the expert / talent isn't a good fit?

If a hired professional does not meet expectations, RolesPilot works quickly to resolve the issue and provide a replacement when necessary. Our vetting process is designed to reduce hiring risk from the beginning, but we understand that team dynamics and project requirements can evolve. Because RolesPilot actively supports the hiring process, companies are not left to manage problems alone. The goal is to ensure you have the right talent in place and a reliable long-term partnership you can confidently scale with.
