C++ Development Services.Safe, Fast, Production-Ready.
Our C++ development services exist for the software where a garbage collector isn't an option and abstraction overhead isn't acceptable — game engines, trading systems, embedded firmware, AI inference runtimes. Modern C++20/23 with smart pointers, concepts, and coroutines. We write C++ that's safe and maintainable, not just fast.

Why Entalogics for C++
Four problems every
inherited C++ codebase
has.
Raw `new`/`delete` scattered across 200 files, no static analysis in CI, undefined behavior that "works until it doesn't," and a build that takes 45 minutes because nobody set up precompiled headers. C++ gives you the power. Most C++ development company work skips the guardrails.
Performance01
Someone optimized the wrong 2% and made the codebase unreadable doing it.
Premature optimization without a profiler is a guess dressed up as engineering. We profile with Perf, VTune, or Tracy first, find the actual hot path, and only touch that — with a before-and-after benchmark proving the gain was real.
Architecture02
The codebase was C with a class keyword bolted on, not modern C++.
RAII for resource management, smart pointers for ownership, `std::span` and `std::string_view` instead of a raw pointer and a length variable passed around separately. The difference between C++23 idioms and 1998 habits shows up in every file.
State03
Ownership lived in a comment, not the type system.
`unique_ptr` when one thing owns a resource, `shared_ptr` only when ownership is genuinely shared, move semantics wherever a copy would be expensive. "// caller owns this" is not a contract the compiler can enforce — a type is.
Type safety04
An `int` was doing three different jobs and nobody could tell them apart.
`std::expected` for recoverable errors instead of an out-of-band error code. Strong typedefs so a `Distance` and a `Duration` can't be swapped even though both compile down to a `double`. The compiler catches what a code review would otherwise have to.
When C++, when not
C++ is a tool.
Not the default choice.
No other mainstream language gives you this much control — and that control costs you in complexity, compile time, and a hiring pool that gets smaller every year. We'll say so on the first call if C++ development isn't actually justified for your problem.
PICK C++ WHEN
- Sub-microsecond latency is a hard number you're accountable for — trading systems, audio engines, real-time control
- The software needs to touch hardware directly — embedded firmware, device drivers, GPU kernels
- An existing C++ codebase needs modernizing, not a rewrite in something else entirely
- Game engines, physics simulation, or rendering — domains where nothing else really competes
CONSIDER RUST WHEN
- Memory safety is a hard compliance requirement and the project is starting from a blank slate
- Your team can invest in learning Rust and the timeline actually allows for that
- You want C++-level performance without carrying C++'s undefined behavior surface area
WE SAY NO WHEN
- "C++ because it's the fastest" — fastest at what? Most API servers ship twice as fast in Go or Java and perform fine
- "C++ for a web backend" — unless you're writing the HTTP server library itself, there are better tools
- "We need this in three weeks" — C++ done properly takes longer, and cut corners here get expensive fast

The playbook
C++ development patterns
we ship on repeat.
Patterns from production C++ systems — not textbook examples that fall apart under real load.
P01
Smart pointers everywhere.
`unique_ptr` for ownership, `shared_ptr` only when genuinely shared. No raw `new`/`delete` in application code — ownership lives in the type system, not a comment.
P02
Static analysis on every PR.
Clang-Tidy, cppcheck, and AddressSanitizer run before merge, not discovered after a 3am production crash.
P03
CMake-first build system.
Modern CMake with targets, precompiled headers configured, build times measured and budgeted. CI stays under 10 minutes.
P04
Concepts instead of SFINAE.
C++20 concepts produce template errors that read like English. Generic code documents its own requirements instead of hiding them in a compiler stack trace.
P05
Benchmark before you optimize.
Google Benchmark on every critical path. No optimization ships without a measured before-and-after, and CI flags regressions the moment they appear.
P06
Modernize incrementally, one file at a time.
`new`/`delete` replaced with smart pointers, macros replaced with `constexpr`, C-style casts removed. The codebase improves continuously — no flag-day rewrite, no feature freeze.
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.

C++11 · raw pointers · 40-min build · 0 static analysis · 3 UB crashes in Q1
After

FAQ
Questions we get on almost
every C++ call.
C++ vs Rust, modernization, undefined behavior, cost — in roughly the order people ask.C++ if you're extending an existing C++ codebase, need mature libraries in your domain, or your team already has deep C++ expertise. Rust if you're starting from scratch and memory safety is a compliance requirement. Both hit the same performance ceiling — the real decision is about your ecosystem and team, not raw speed.
Yes. File by file, one smart pointer at a time. Sanitizers, static analysis, and modern idioms go in incrementally while the system keeps running under live load throughout.
AddressSanitizer and UBSan run in CI on every PR, catching the UB that "works in testing" but crashes in production. Combined with Clang-Tidy, most of it gets eliminated before it ever reaches code review.
Depends on scope and how much legacy code exists. The week-one audit gives us real numbers — the quote is fixed from there, not a range that creeps with every sprint. Most engagements run fixed-price or on a dedicated monthly rate, whichever fits your stage better.
Yes. The engineers who write the RFC ship the code. No handoff mid-engagement, no account manager in between.
Yes. Makefiles, CMake, Bazel, or fully custom — we adapt to your conventions and flag anything that genuinely needs modernizing in the RFC.
