NEXUS-CPP
NEXUS-CPP
NEXUS-CPP is a modular C++20 software engine designed for data processing, analytics, simulation, workflow orchestration, and resource management. The project brings together multiple integrated subsystems, including caching, scheduling, configuration management, validation, security, observability, event processing, aggregation, time-series analysis, and automated testing. Built with a focus on modular architecture, maintainability, performance, and extensibility, NEXUS-CPP provides a foundation for developers and engineering teams looking to expand an existing systems-engineering codebase rather than build every component from scratch. The project is available for acquisition, licensing, or further commercial development, subject to mutually agreed terms. The repository and its components can be reviewed by serious buyers, with source-code access and intellectual property transfer arrangements discussed directly. Ideal for C++ developers, infrastructure engineering teams, and companies seeking a reusable foundation for backend systems, data infrastructure, or developer tooling.

NEXUS C++ Engine
A modular C++20 engineering project for data processing, analytics, workflow execution, resource management, and system observability.
NEXUS is a multi-component C++ project built around reusable engine modules, explicit configuration, operational metrics, and testable subsystem behavior.
The repository combines a main application with separately maintained engine components and supporting tests.
Project Overview
NEXUS explores how multiple infrastructure-style subsystems can be implemented and integrated in modern C++.
The project emphasizes:
- Modular architecture and separation of responsibilities
- C++20 implementation
- Reusable engine components
- Configuration and input validation
- Monitoring, metrics, and alert lifecycle management
- Workflow and task execution capabilities
- Automated compilation and test workflows
Core Components
The codebase includes components for several engineering domains:
| Domain | Components |
|---|---|
| Data processing | Query processing, pipelines, aggregation, time-series operations |
| Runtime execution | Task scheduling, workflow orchestration, simulation |
| Data management | Caching, storage, durable workflow persistence |
| Configuration | Configuration loading and validation |
| Reliability | Circuit breaking, bulkheads, resource quotas |
| Security and operations | Security controls, audit logging, observability |
| Quality assurance | Component-specific test programs and integration checks |
The exact integration level and available APIs depend on the individual component. Refer to the source and associated test files for implementation details.
Architecture
NEXUS uses a modular source layout.
nexus_v2.0.0_work.cpp— main application and integration entry point.*_engine.inc— engine implementations included by the main application.*_test.cpp— standalone component test programs where provided.README.md— project documentation.
The .inc files are C++ implementation fragments intended to be compiled in their integration context unless a component's test harness provides a separate entry point.
Technology Stack
- Language: C++
- Language standard: C++20
- Compiler: GCC / G++
- Build environment: MSYS2 UCRT64 on Windows
- Build options: Optimization, compiler warnings, and POSIX thread support through
-pthread
Build
Install a working C++20 compiler in the MSYS2 UCRT64 environment, then run:
g++ -std=c++20 -O2 -Wall -Wextra -pthread \
nexus_v2.0.0_work.cpp \
-o nexus_v2.0.0_work.exe
If compilation succeeds, run the application:
./nexus_v2.0.0_work.exe
Build output and runtime results depend on the current source version and local environment.
Testing
The repository contains standalone component tests and integration checks.
A component test can generally be compiled using the same compiler settings, for example:
g++ -std=c++20 -O2 -Wall -Wextra -pthread \
observability_engine_test.cpp \
-o observability_engine_test.exe
Run the resulting executable:
./observability_engine_test.exe
Some test programs include or exercise shared engine components. Follow the individual test source and its dependencies when building other modules.
For reproducible evaluation, record the compiler version, build output, test results, and source revision.
Current Status
NEXUS is an actively developed engineering codebase. Its components cover data processing, execution, persistence, configuration, reliability, security, and observability.
The v2.0.0 filename identifies the current development line; it should not be interpreted as a guarantee of production certification or a stable public API.
Potential Applications
Depending on further integration, documentation, and validation, the architecture may serve as a foundation for experimentation with:
- Modular data-processing applications
- Workflow and task execution systems
- Monitoring and alerting components
- Reliability and resource-control mechanisms
- C++ infrastructure and systems-engineering prototypes
These are potential application areas, not claims of independently verified commercial deployment.
Evaluation
Developers and prospective collaborators can evaluate the project by:
- Reviewing the engine implementations and public interfaces.
- Building the main application with a supported C++20 compiler.
- Running the available component tests.
- Inspecting error handling, concurrency behavior, persistence, and resource limits.
- Reproducing reported results in their own environment.
