Self-taught Web Developer Journey
My journey into frontend development began with a passion for learning and coding. As an autodidact, I regularly watched technical YouTube channels like Syntax, Wes Bos, Jack Herrington, Hamed Bahram, Dave Gray, and many others to deepen my knowledge (I'm grateful for their valuable content and guidance). Through practical application, I developed strong skills in React.js and JavaScript, while staying up-to-date with the latest tech trends by reading articles on Medium and DEV Community. This relentless pursuit of learning and embracing new technologies has shaped me into a capable and adaptable developer.
