C++ done rightsafe, fast, modern.
C++ development services for systems where garbage collection isn't an option and abstraction overhead isn't acceptable. Game engines, trading systems, embedded firmware, AI inference runtimes — the software that runs underneath everything else. Modern C++20/23 with smart pointers, concepts, and coroutines. We write C++ that's safe, fast, and maintainable — not just fast.

Why Entalogics for C++
Four things every
C++ codebase
actually needs.
The C++ codebases we inherit usually have raw `new`/`delete` scattered across 200 files, no static analysis in CI, `undefined behaviour` that "works in production until it doesn't", and build systems that take 45 minutes because nobody set up precompiled headers. C++ gives you the power. Most teams don't add the guardrails.
Performance01
Profile first. Then optimise the right thing.
Premature optimisation in C++ creates unreadable code for a 2% improvement nobody measured. We profile with Perf, VTune, or Tracy, identify the actual hot path, and optimise that — with benchmarks that prove the improvement before and after.
Architecture02
Modern C++ idioms, not C with classes.
RAII for resource management. Smart pointers for ownership. `std::span` and `std::string_view` instead of raw pointer + length pairs. The codebase reads like modern C++, not 1998 C++ with a class keyword.
State03
Ownership expressed in the type system.
`unique_ptr` for single ownership. `shared_ptr` only when shared ownership is genuinely required. Value semantics by default. Move semantics where copies are expensive. Ownership is explicit — not a comment that says "// caller owns this."
Type safety04
`std::expected` over error codes. Strong types over raw `int`.
C++23's `std::expected` for recoverable errors. Strong typedefs to prevent unit confusion — a `Distance` is not a `Duration` even though both are `double`. The compiler catches the misuse. A code review shouldn't have to.
When C++, when not
C++ is a tool.
Not the default choice.
C++ gives you control no other mainstream language offers. That control has a cost — complexity, compilation time, and a hiring pool that shrinks every year. We'll tell you on the first call if C++ is genuinely justified for your problem.
PICK C++ WHEN
- Sub-microsecond latency is a hard requirement — trading systems, audio engines, real-time control
- Direct hardware access — embedded firmware, device drivers, GPU kernels
- Existing C++ codebase that needs modernisation, not a rewrite in Rust
- Game engines, physics simulations, or rendering pipelines where no other language competes
CONSIDER RUST WHEN
- Memory safety is a hard compliance requirement and you're starting from scratch
- The team is willing to invest in learning Rust and the project timeline allows it
- You need C++-level performance without C++'s undefined behaviour surface area
WE SAY NO WHEN
- "C++ because it's the fastest." Fast at what? For most API servers, Go or Java is fast enough and ships in half the time.
- "C++ for a web backend." Unless you're writing an HTTP server library, there are better tools.
- "We need this in three weeks." C++ done right takes longer than that. Cut corners and you'll pay for them later.

C++ modernisation

The playbook
Patterns we
ship on repeat.
C++ patterns from production systems — not textbook examples.
P01
Smart pointers everywhere
`unique_ptr` for ownership. `shared_ptr` only when genuinely shared. No raw `new`/`delete` in application code. Ownership expressed in the type system, not in comments.
P02
Static analysis in CI
Clang-Tidy, cppcheck, and AddressSanitizer on every PR. Undefined behaviour caught before merge — not after a crash in production at 3am.
P03
CMake-first build system
Modern CMake with targets, not variables. Precompiled headers configured. Build times measured and budgeted. CI builds in under 10 minutes.
P04
Concepts for constrained templates
C++20 concepts instead of SFINAE. Template errors that read like English, not like compiler core dumps. Generic code that documents its own requirements.
P05
Benchmark-driven optimisation
Google Benchmark on critical paths. No optimisation without a measured before and after. CI alerts on performance regressions across releases.
P06
Incremental modernisation
One file at a time. Replace `new`/`delete` with smart pointers. Replace macros with `constexpr`. Replace C-style casts. The codebase improves continuously — no flag-day rewrite.
Signature case
A trading system,
modernised from C++11 to C++23 under live load.
A high-frequency trading system on C++11 — raw pointer ownership nobody could trace, a Makefile build taking 40 minutes, zero static analysis, and three production crashes in one quarter from undefined behaviour that "worked in testing." Modernised to C++23 with smart pointers, CMake, sanitizers in CI, and `std::expected` error handling in 10 weeks. Under live market load the entire time.
Before
C++11 · raw pointers · 40-min build · 0 static analysis · 3 UB crashes in Q1
After
C++23 · smart pointers · 8-min build · Clang-Tidy + ASan in CI · 0 crashes in Q2+Q3
- Build time−80%
- UB-related crashes3 → 0

Engagement shape
Eight to ten weeks
to a measurable ship.
A typical C++ development engagement. We modernise or build module by module — the system keeps running while we work.
- W01
Audit + RFC
Two senior C++ engineers. Profiling, sanitiser analysis, build system review, ownership audit. A ranked, dollarized RFC.
- W02–03
Foundation + first module
CMake baseline, sanitisers in CI, smart pointer conventions established, one production module modernised end-to-end. Real benchmarks on target hardware.
- W04–08
Module by module
File by file under feature flags where applicable. Sanitisers and benchmarks on every PR. Your system keeps running.
- W09+
Release + handoff
CI clean. Benchmarks documented. Runbook handed to your team — or we stay on retainer.

FAQ
Sharp questions,
straight answers.
C++ vs Rust, modernisation, undefined behaviour, existing codebases — the questions we get on every C++ discovery call.C++ if you're extending an existing C++ codebase, need mature libraries in your domain (game engines, trading, embedded), or your team already has deep C++ expertise. Rust if you're starting from scratch and memory safety is a compliance requirement. Both produce the same calibre of performance. The decision is about ecosystem and team, not speed.
Yes. File by file, one smart pointer at a time. We add sanitisers, static analysis, and modern idioms incrementally. The system keeps running under live load throughout.
AddressSanitizer and UBSan in CI on every PR. They catch the UB that "works in testing" but crashes in production. Combined with Clang-Tidy checks, most UB is eliminated before it reaches code review.
Yes. The engineers who write the RFC ship the code. No handoff mid-engagement. Direct access throughout.
Yes. We've worked inside Makefiles, CMake, Bazel, and fully custom build systems. We adapt to your conventions. If the build system needs modernising, we flag it in the RFC.
