Hi! 👋

I’ve added my Next.js project Snappaste under the "Abhishek Gawande" folder. It’s a website that lets you quickly replicate the grab-and-paste feature, similar to Huawei phones.

I’ve also updated the README inside my folder to include details about me and my projects.

Hope this helps in reviewing my contribution. Let me know if you have any suggestions!
