About me
I'm Juan Andrés Leiva, a software engineer and solutions architect based in Latin America. I write about AWS, .NET, and software architecture in English and Spanish, sharing real-world experience from production systems.
My work spans cloud infrastructure with AWS, backend development with .NET and C#, and frontend engineering with React and Next.js. I believe in practical, no-nonsense technical writing that helps developers solve real problems.
What I write about
- .NET & C# — API design, Entity Framework, performance patterns, and new language features
- AWS — IAM, S3, CloudFront, Aurora, Terraform, and cloud architecture
- JavaScript & React — React patterns, Next.js, TypeScript, and frontend best practices
- DevOps — CI/CD, Docker, GitHub Actions, and infrastructure as code
- Databases — PostgreSQL, vector databases, and data modeling
