About Me

Hi! I'm Denis Peshkov — a Software Engineer & System Architect with over 20 years of software development experience. My expertise includes architecture design, high-load system development, and creating open-source tools for the developer community.

What I Do

Open-Source Projects

I actively develop and maintain several open-source libraries for the .NET ecosystem:

  • Cross.Identity — library for identity management in distributed systems
  • Cross.CQRS / Cross.CQRS.EF — tools for implementing CQRS pattern with Entity Framework
  • Other libraries to simplify enterprise application development

These projects help developers build reliable and scalable systems faster, following architecture best practices.

Commercial Projects

I also work on commercial projects in HealthTech, FinTech, and Education, building SaaS platforms with a focus on quality, reliability, and scalability.

Why Your Support Matters

Your sponsorship helps me:

  • Dedicate more time to open-source projects — improve documentation, fix bugs, add new features
  • Maintain code quality — conduct code reviews, write tests, improve architecture
  • Share knowledge — create educational materials, usage examples, best practices
  • Grow the ecosystem — build tools that save time for thousands of developers

What You Get

Sponsors receive:

  • Priority support in issues and discussions
  • Early access to new features and experimental capabilities
  • Mention in project READMEs (optional)
  • Ability to influence project roadmaps

Thank You!
