Hire senior Kotlin experts
We build concise, safe Kotlin applications for backend and Android, modern, expressive code that cuts bugs and speeds up delivery.
This is for teams building or scaling a backend on Kotlin, whether that's a new API-first product, a service under real load, or an existing Kotlin codebase that needs a steadier footing.
Custom Kotlin Development Services
We build Kotlin applications that drop into the architecture and data models you already run, rather than fighting them. Backend reliability, clean service boundaries, and systems that scale without a rewrite are what we optimise for, so delivery stays quick and the platform keeps extending confidently as the roadmap moves.
Kotlin Backend Development
We build concise, safe Kotlin backends with Ktor and Spring Boot, coroutine-based services that handle concurrency cleanly and cut the null-pointer and boilerplate bugs that slow Java teams down.
How we help
We settle the architecture and data model first, then ship secure, well-tested services in reviewable increments with monitoring wired in from the start.

We build Kotlin across the stack, native Android with Jetpack Compose and shared business logic with Kotlin Multiplatform so mobile, backend, and even iOS can share code without compromise.
How we help
We choose what to share via Multiplatform deliberately, keep platform code clean, and structure modules so teams ship in parallel.
We build high-throughput Kotlin systems with coroutines and Flow, structured concurrency that handles async work and streaming data safely, without the callback tangle of older approaches.
How we help
We use structured concurrency and Flow deliberately, reason about cancellation and back-pressure, and test concurrent paths so behaviour stays predictable.
We modernise Java codebases to Kotlin incrementally. Kotlin and Java interoperate seamlessly, so we migrate module by module, cutting boilerplate and null-safety bugs without stalling delivery.
How we help
We migrate in slices behind tests, exploit seamless Java interop, and keep the system shippable so modernisation happens alongside feature work.
We build Kotlin APIs and microservices with clean contracts, strong validation, and clear error handling, endpoints that behave predictably under load and integrate cleanly with the rest of your stack.
How we help
We settle the contract and auth model first, then ship endpoints with tests, docs, and monitoring so other teams build against them confidently.
We tune and modernise Kotlin services, profiling hot paths, upgrading dependencies, and refactoring toward clean, testable modules so the platform stays fast and maintainable as it grows.
How we help
We measure before changing anything, target the real hotspots, and verify each fix against production-like load.
Kotlin experts, AI-augmented
These are the AI coding tools our engineers use to ship faster and keep code clean, distinct from the AI systems we design and build for you.
We use these tools inside strict guardrails, every line is reviewed by a person. See how we build →
Senior Kotlin engineers
Senior engineers with deep, hands-on Kotlin experience building production systems at scale.
Proven across industries
Our Kotlin teams have delivered backend work across healthcare, finance, retail, and logistics, bringing domain awareness and hard-won patterns to every engagement.
Enterprise-ready delivery
We hold high standards for security, testing, and documentation, and can scale a Kotlin team up or down without sacrificing speed or quality.
The Kotlin toolset
The Kotlin tooling we rely on, grouped by what it does, and chosen deliberately from experience. Pick an area to see what we reach for and why.
We deploy Kotlin applications on battle-tested servers and runtimes that support both traditional synchronous and modern asynchronous workloads in a controlled, production-ready environment.
We deploy Kotlin applications on battle-tested servers and runtimes that support both traditional synchronous and modern asynchronous workloads in a controlled, production-ready environment.
We build Kotlin APIs and data-access layers with clear contracts, strong validation, and efficient queries so clients and services integrate cleanly.
We pair Kotlin with the right databases and persistence tooling, modelling data for correctness, integrity, and performance under load.
We move heavy, scheduled, and long-running work off the Kotlin request path into reliable background jobs and async processing.
We keep Kotlin fast under real traffic with layered caching, connection pooling, and targeted performance tuning.
We hold Kotlin code to a high bar with automated tests, coverage, and static analysis wired across the pipeline.
We secure Kotlin applications with proven authentication, authorization, and data-protection tooling built in from the start.
We ship Kotlin reliably with containerisation, CI/CD, and infrastructure that makes deployments routine and reversible.
