About Ewen

Hello 👋

I'm Ewen Emeraud, a developer specializing inRust, C, C++, and AI integration.

I assist startups, SMEs, and technical teams in creating high-performance tools, system applications, backend software, and AI-integrated solutions tailored to their business needs.

I handle projects from conception to production, with a focus on performance, reliability, code quality, and maintainability.

📋 Services I offer:
  • Development of tools in Rust, C, and C++
  • Development of system software and Linux applications
  • Creation of CLIs, daemons, backend services, and native modules
  • Performance optimization and refactoring of existing code
  • Debugging, bug fixing, build or compilation issues
  • Integration of AI into business tools: RAG, LLMs, automation, data analysis

🔧 Key Technologies:
  • Rust / C / C++
  • Linux, Unix, low-level systems
  • Cargo, CMake, Makefile
  • Git, Docker, GitHub Actions
  • Backend APIs, services, CLI tools
  • AI Integration: OpenAI, local LLMs, RAG, automation

🔁 My 4-step methodology
  • Kick-Off:understanding your needs, technical constraints, and objectives
  • Scoping & Architecture:technical choices, project structure, definition of modules and deliverables
  • Iterative Development:clean implementation, regular deliveries, continuous testing and feedback
  • Delivery & Follow-up:documentation, optimization, post-delivery support, and potential evolutions

🎯 Why collaborate with me?
  • Solid technical expertise
  • Performance-oriented approach
  • Clean and maintainable code
  • Experience on diverse projects

📩 A system tool to develop, an application to optimize, or an AI solution to integrate?

Let's discuss it!
