Development Philosophy

struct Engineer {
    experience_years: u8,
    core_principle: &'static str,
    standards: Vec<&'static str>,
}

let chrono = Engineer {
    experience_years: 30,
    core_principle: "Privacy and security by design, not as an afterthought",
    standards: vec![
        "Production-grade code quality (zero warnings, comprehensive tests)",
        "Formal security analysis for cryptographic protocols",
        "Build from first principles, avoid unnecessary dependencies",
        "Complete documentation with clear architecture diagrams",
        "Open source with academic rigor"
    ],
};

All projects are fully open-source with comprehensive documentation. Code is production-quality: zero compiler warnings, complete error handling, extensive testing.

Research papers and formal protocol specifications included where applicable.

Philosophy: Build from scratch. No frameworks for framework's sake. Performance and security by design.
