Kotlin Code Review & Bug Report — Up to 500 Lines

I will conduct a thorough review of up to 500 lines of your Kotlin code and deliver a detailed report covering bugs, null safety violations, coroutine misuse, memory leaks, architectural anti-patterns, and deviations from Kotlin idiomatic best practices — with specific line references and remediation recommendations for every finding. Kotlin's null safety system is one of its greatest strengths, but it is routinely bypassed with unsafe casts and platform type assumptions that compile cleanly and crash in production.

The review covers nullable type handling, coroutine scope and dispatcher misuse, Flow collection on the wrong lifecycle scope, sealed class exhaustion, data class misuse, companion object anti-patterns, and extension function overuse. Each finding is categorised by severity with a specific Kotlin code fix recommendation.

This service suits Android developers, backend Kotlin teams, and businesses preparing Kotlin code for production, audit, or handover who need an expert assessment of quality and risk before investing further.
