๐ Hi, there welcome to my GitHub! I'm a computational chemistry wizard ๐งโโ๏ธ obsessed with understanding molecules through data ๐! I perform quantum calculations ๐คฏ to see electrons dance, run molecular simulations ๐ฌ to watch molecules move, and build ML models ๐ to predict chemical properties. My pipelines screen thousands of compounds ๐๏ธ and crunch big chemical data ๐ to discover new insights. I develop tools in Python and C++ ๐ ๏ธ to analyze all the things about molecules! My chemistry spells and algorithms transform raw data into molecular insights. Let's use the power of computation to advance medicines, materials and more! ๐
