Kotlin Development in Chichester
Building with Kotlin for Chichester organisations, where the practical gain over Java is that null is part of the type system. A value that cannot be absent is enforced by the compiler rather than by convention — except at the boundary with Java, where types arrive with no such guarantee and the checking quietly stops applying.
Why this comes up
The problem
The Kotlin code is null-safe throughout, and the values arriving from a Java library are not, and nothing warns anybody.
What you get
What we deliver
- Java interop boundaries handled explicitly, where nullability is unknown
- Annotations added to Java code you own so the compiler can see the intent
- Coroutines used with a defined scope, so work is cancelled when it should be
- Data classes and sealed types used to model the domain rather than describe it
- Null assertions treated as a code smell rather than a convenience
- Interoperability tested where Kotlin and Java call each other

Kotlin Development in Chichester — common questions
- Where does null safety stop working?
- At the Java boundary. Values from Java arrive as types the compiler cannot verify either way, so it permits both — and a null flows into code that assumed it could not, producing exactly the failure the language was meant to prevent.
- What can we do about it?
- Annotate the Java code you control so the compiler knows, and treat everything from third-party Java as nullable until checked at the boundary. It is a small discipline that restores the guarantee across the join.
- Why does coroutine scope matter?
- Because it determines what gets cancelled. Work launched without a scope tied to a lifecycle continues after whatever requested it has gone — the same class of leak as an unbounded thread, and equally invisible until memory grows.
- Is the double-bang operator ever appropriate?
- Rarely, and each use is worth questioning. It asserts a value cannot be null and throws if it is, which converts a compile-time guarantee back into a runtime failure — usually a sign the type should have been handled properly instead.
- Do you work with businesses across West Sussex?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Chichester and the surrounding West Sussex area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Chichester businesses do you usually work with?
- Booking and ticketing for arts and marine operators, built to survive a season that carries the whole year. Beyond that we work across Tourism & Heritage, Agriculture, Marine, Arts & Culture and Retail.
- Do you cover the areas around Chichester?
- Yes — we work throughout South East, including Southampton, Portsmouth, Brighton. Chichester is an urban area of roughly 30,000+, and we take on work across the wider West Sussex region rather than the city boundary alone.
