Our Kotlin Expertise

Infuse Your Vision With Our Innovation

Kotlin is a statically typed language for the Java Virtual Machine (JVM) and JavaScript that can be used to build a diverse range of Android mobile apps. JetBrains (the company behind the IntelliJ IDE) developed it as an open-source programming language that is now widely used to develop Android apps, alongside Java. In addition to offering many of the attributes familiar to Java developers, Kotlin app development is all about Object-Oriented Programming. Businesses need a committed technological partner in these competitive times, to handhold them through the Android software life-cycles, debugging, and CI/CD.

This is where HourlyDeveloper can be of critical assistance. HourlyDeveloper’s experienced engineers leverage Kotlin’s numerous benefits, which carry forward Java’s legacy as the now-de facto Android programming language. Additionally, at HourlyDeveloper we orchestrate complex application programming logic with Kotlin's sophisticated function implementation and Functional Programming perks. This is because Kotlin offers syntactic advantages that permit the development of programs with lesser coding in comparison to contemporary or older languages.

Kotlin App Development Services

Kotlin is useful as a general-purpose programming language since its interoperability with other languages renders the easy creation of new features, platform support extensions, and legacy Java-based Android app migrations. At HourlyDeveloper, we rely on Kotlin to develop complex programs with high-order functions. We also dispense a number of Kotlin-oriented services for business enterprises.

Custom Kotlin App Development

Custom Kotlin App Development

We can help develop any kind of custom Android application using Kotlin. Since it has become the default language for native Android development, Kotlin has espoused numerous plugins and library extensions that facilitate Android app development. We can leverage these for enterprise-scale as well as startup-scale, custom app development requirements.

Kotlin Server-side Development

Kotlin Server-Side Development

Kotlin frameworks like Ktor, Micronaut, Javelin, etc. are extremely useful for developing server-side applications. Our developers rely on its type-safe builders and delegated properties to build powerful abstractions. Kotlin supports co-routines that allow it to scale and support an incremental number of users. We strongly recommend Kotlin web development for server-side scripting, all the more, as it is interoperable with any Java-based framework.

Why Opt For Kotlin App Development Services?

Similarity to Java

Similarity To Java

The Kotlin code reads very similarly to Java code, with some minor syntactic differences. Its conciseness due to data classes, smart casts, type interfaces, etc. makes it the ideal successor to an Android programming language.

Kotlin Functions

Kotlin Functions

Kotlin allows us to declare local functions as member functions or extension functions. We can even choose to declare functions outside of classes. Hence, despite being an OOP language, Kotlin is more liberal about method declarations, which reduces class size bloat.

Kotlin Compiler

Kotlin Compiler

The Kotlin compiler facilitates an LLVM technology that compiles code sources as standalone binaries for various supported platforms. It helps detect compile-time errors ahead of runtime, thanks to a ‘fail-fast’ approach.

Kotlin Runtime

Kotlin Runtime

The Kotlin runtime class library encapsulates the JVM, JavaScript, and native binary compilers so that when the developer compiles the code, it is compiled in Dex bytecode format or Dalvik bytecode first. This allows Kotlin to extend legacy apps as well as newly coded ones.

Error Handling Perks

Error Handling Perks

Kotlin boasts of the ‘throwable’ class library that facilitates every exception required by the developer under the most common programming circumstances. This allows our developers to avoid error-prone practices like creating in-built null references under checked exceptions.

Memory Management Benefits

Memory Management Benefits

Kotlin improves memory management using the Concurrent Mark-Sweep algorithm, which facilitates automated memory management and cyclic garbage collection, using an automated reference counter.
