What programming languages are you proficient in?

I'm proficient in a variety of programming languages, including but not limited to:

1. **Python**: Python is widely used for general-purpose programming, data analysis, artificial intelligence, and web development.

2. **JavaScript**: JavaScript is essential for front-end web development, creating interactive elements on websites, and increasingly used in server-side development (Node.js).

3. **Java**: Java is a versatile language used for building desktop applications, backend services, and Android app development.

4. **C++**: C++ is used in systems/software development where performance and efficiency are critical, such as in game development, operating systems, and embedded systems.

6. **SQL**: SQL (Structured Query Language) is essential for database management and data manipulation.

7. **HTML/CSS**: Although not strictly programming languages, HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets) are fundamental for web development.

8. **Ruby**: Ruby is known for its simplicity and productivity, used mainly in web development with frameworks like Ruby on Rails.

9. **PHP**: PHP is widely used for server-side web development and scripting.

10. **Swift**: Swift is used for developing applications for Apple's iOS, macOS, watchOS, and tvOS platforms.

Additionally, I can understand and discuss concepts related to other languages and frameworks, even if I may not be proficient in writing code in all of them. If you have specific questions about any programming language or technology, feel free to ask!
