Hola, I’m Cesar Aguirre!

I help teams grow high-quality backend code. And by high-quality, I mean maintainable and performant.

I’m a software engineer, lifelong learner, language enthusiast, and avid reader. I work remotely from Colombia (not Columbia) as a C# backend engineer and technical writer.

These are some projects I've done for past employers and clients:

• I wrote a library to connect 4 clients with legacy software to an invoicing platform by parsing pdf and plain text files into input XML files.
• I improved the response time of the room search functionality of a booking page by a factor of ~1.5X, removing bad practices and adding a caching layer.

I blog to share my journey as a software engineer. I write about books I read, libraries I use, bugs I find, and things I learn.

These are some of my favorite posts:

• ASP.NET Core Guide for ASP.NET Framework Users
• How to add a caching layer with ASP.NET Core
• Parsinator, a tale of a PDF parser
• What the Func, Action?
• The C# Definitive Guide

Read my blog, learn about me, and check my projects.

Happy coding!
