Expert AWS consulting for .NET and Node.js teams ready to transform legacy systems into cloud-native architectures
I'm Dan Guisinger, a senior cloud architect with over 20 years of enterprise application experience. I've helped organizations across healthcare, finance, and technology sectors build and modernize mission-critical systems. My journey has taken me from building complex .NET applications to architecting cloud-native solutions on AWS.
I specialize in .NET systems, serverless architectures, and AWS-native automation. Whether it's migrating legacy applications to the cloud, implementing CI/CD pipelines, or hardening security posture, I bring a practical, results-focused approach that balances technical excellence with business value.
My long-term engineering and architecture roles across multiple industries have consistently improved delivery speed, reliability, and security for enterprise teams. I've maintained continuous enterprise contracts for over 9 years, building lasting relationships through consistent delivery and technical leadership.
