My Projects' Directory


VertiKin is an e-commerce platform which allows the user to search through various products. It has a one-of-its-kind feature of automatically detecting what user might be interested in buying in near future.
VertiKin Mobile app learns from user inputs on his phone (we do not read passwords and private information, so the user can be assured of his security). This data is sent to the VertiKin server, where using Natural language processing (NLP), important information is extracted and using frequency as a parameter, it tries to find if the user is interested in buying some product or not. If so, a GCM push notification is sent to the user.
Let's say VertiKin realised user wants to buy product A, but user did not want it, we give him a small feedback form, where he simply needs to click No and VertiKin would improve the suggestion from next time. User starts with a DEFAULT_THRESHOLD and according to the user feedback, user threshold changes by THRESHOLD_DELTA.

WhatsApp Reader

WhatsApp Reader is a PHP based web based application to easily see your chats with your friends in a familiar user interface of WhatsApp, because reading from the backup text file is too boring. It asks you to upload the ".txt" file of your chat. You can get the ".txt" file from the Email Conversation button in your WhatsApp.

It may not be 100% correct, since I simply built this to read a piece of chat I found in my Inbox, and I hope it is useful for several others like me.

Village Connect

In simpler terms, the idea is to create a local interweb which enables the rural areas' residents to consume internet data without even getting connected to the internet.
If 100 people from a village want to access some particular educational videos, rather than making all of 100 of them to download those videos at their own ends, central hub will have those videos saved on the system. Anyone who is connected to the local network of the central hub, will be able to access and watch those videos as if they were present on their own local system.
