About Oscar

I find it hard to categorize myself under one title, but I usually define myself as a full-stack web developer.
For over 10 years, I've been helping companies and professionals with their web projects, especially with custom applications that need to deliver optimal performance.

During these years, I've gained experience in various areas beyond development, such as server administration or cloud environments, database administration, and aspects like design and user experience.

I've also had to deal with different languages, frameworks, and trends... which has taught me how to handle legacy code and the importance of applications scaling over time, as well as choosing the technologies that best suit each environment.
