C++ Development in Portsmouth
Building with C++ for Portsmouth organisations, where the defining discipline is that resources have owners. Modern practice ties every allocation to an object's lifetime so it is released automatically — and code that manages memory manually is not merely old-fashioned, it is the source of the failures that are hardest to reproduce.
Why this comes up
The problem
A crash appears in production once a week, in a different place each time, and never reproduces under a debugger.
What you get
What we deliver
- Ownership expressed through types rather than through convention and comments
- Manual allocation replaced with scoped and shared ownership where appropriate
- Sanitisers and static analysis run in the build, not occasionally by hand
- The language standard targeted decided explicitly and applied consistently
- Undefined behaviour treated as a defect class rather than a curiosity
- Build system and dependencies rationalised, since these become unmanageable quietly

Working in Portsmouth
South East
Portsmouth is densely built on an island site with a naval dockyard and a commercial ferry port, so logistics businesses here work under physical constraints that inland operators do not face.

C++ Development in Portsmouth — common questions
- Why are these crashes so hard to reproduce?
- Because undefined behaviour does not fail where it occurs. Writing past the end of an allocation corrupts something used later, so the crash appears in unrelated code — which is why the debugger points at innocent functions and the pattern seems random.
- What do sanitisers give us?
- Failure at the moment of the mistake rather than later. Running tests with address and undefined behaviour sanitisers turns a mysterious production crash into a clear message at the exact line, and it belongs in the build rather than being an occasional exercise.
- How much does the standard version matter?
- It determines which language facilities are available and how much manual work remains. Targeting a modern standard removes a large amount of error-prone code, and the constraint is usually the toolchain on the platforms you must support.
- Is dependency management still difficult?
- Less than it was, and it needs a deliberate choice. Projects that never adopted a package manager accumulate vendored copies of libraries that nobody updates, which becomes a security problem long before anyone treats it as one.
- Do you work with businesses across Hampshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Portsmouth and the surrounding Hampshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Portsmouth businesses do you usually work with?
- Port, ferry and defence logistics systems, plus visitor operations for the waterfront attractions. Beyond that we work across Marine & Defence, Ports & Ferries, Higher Education, Retail and Tourism.
- Do you cover the areas around Portsmouth?
- Yes — we work throughout South East, including Southampton, Chichester, Brighton. Portsmouth is an urban area of roughly 240,000+, and we take on work across the wider Hampshire region rather than the city boundary alone.
