Decoded
Brain

I'm a seasoned Python developer with over 3 years of experience in data science, cryptocurrency, and related fields. My passion for problem-solving and data-driven decision making has led me to develop innovative solutions in these areas. I've honed my skills in Python, SQL, and machine learning libraries like Scikit-learn, TensorFlow, and PyTorch. I've also gained proficiency in data visualization tools such as Matplotlib and Seaborn, which I use to present complex data in an understandable manner. My work in the cryptocurrency domain has been particularly rewarding. I've developed predictive models for cryptocurrency prices, built blockchain applications, and worked on smart contracts using Solidity. I've also contributed to open-source projects in the crypto space, enhancing my understanding of decentralized finance (DeFi).
