Android Library to easily integrate Dialogflow based chatbots into an existing application with Chat screen.
Various chat-UI features controlled from backend webhook
I designed this library as I had been receiving queries from the fellow developers from around the world on how to integrate Java-based Dialogflow V2 after Google deprecated the older V1 version and api.ai library. Using my experience, I designed this library to easily integrate the chatbot into an Android app. Using the library, the developers will have multiple chat UI features including card layout, checkboxes and image carousel which are controlled from the backend. There is no need to make any code changes in the Android app. For details, check the following Medium article Android Dialogflow Chatbot Library. The open-source code could be accessed from the following GitHub project Android Dialogflow Chatbot Library.

The aim is to design and develop an AI/ML based Chatbot engine that can be integrated into different mobile and web based applications. Along with chatbot, the project aims to introduce features that will improve the usability of Android applications especially for visually impaired through innovation and best practices in application development.
Can't show actual implementation as it is still under development. Works similarly as shown in the above video along with the action buttons and radio/checkbox options within the chat.
As part of the innovation lab, I am the subject matter expert for the Dialogflow platform for the project. My role is to research and develop a proof of concepts showcasing information exchange between the Android and the Dialogflow based chat engine and help in architecture development. Once concepts get approved, I developed the NodeJS based chatbot webhook and integrate it with the existing client backend services. I also designed the Android chat UI and integrated it with the webhook and into the existing Android app.
I also researched on how to utilize Dialogflow capabilities for improving search results for the users of websites and mobile applications.
I advocated the use of NFC to improve application usability by visually impaired and the developed a prototype which after approval has been integrated into the Android app by the development team. Currently, I am working on improving the accessibility features of the Android app by following best practices.

Secure Location demonstrates how a location can be identified using Bluetooth LE-based beacons and implement organization policies on the device to make it secure. In this concept application, if a user enters a secured location (marked by beacon), then camera of the device is disabled. Once the user exits the secure location, the camera is enabled automatically. This use case can be enhanced to automatically activate different policies and settings on devices when inside a specific location. This use case can also be used for other purposes like indoor beacon-based navigation, announcements, advertisements, etc.
The application was designed during an online hackathon and was selected in top 18 finalists out of 60+ teams. It showcases solution to real world problem and implementation that can serve many use cases, for instance, it can be modified to put phones on "Silent Mode" in meeting rooms, theaters, and hospitals automatically.
As I developed this concept application, I developed logic to scan Bluetooth LE devices and detect registered beacons using their UUID. The existing third party APIs didn't serve my purpose to run the application in the background even when the user kills it. I have improved this shortcoming and was able to scan and detect beacons using background service with minimal battery usage. Once the service is started it keeps running in background and scan for beacons at regular interval of time that can be varied as per user settings.
SHOOT is a classic stress buster game where the goal is to shoot down all the floating items by touching on them. It has a collection of different items and levels to play with. The level gets completed when all items are blown before the timer is finished. There is a check on miss-hits in advanced levels indicated by bullet icon. New items and levels get unlocked when you successfully complete a level. Gameplay difficulty increases with item movement, speed, and random behavior. This can be varied further via the settings menu.
Everyone likes to play video games. As I started learning programming I wanted to develop a game one day. To learn the concepts of game development and test my programming skills, I developed SHOOT. I designed it end-to-end without the use of any third party library. During the course of development I learned the basic concepts of Game Development - Story Play, Game-Loop, Frame-Rate, Game Mechanics, Animation using Sprites, Image Rendering on Canvas.

theVault is a Password managing app for Android. Users can store their passwords for websites, emails, bank accounts etc. securely in the application. User data is encrypted using custom encryption algorithm based on AES and BASE64 encoding. There are no permissions required to install the application. Data remains on the device itself and not on any server, so there is no danger of hacking and privacy leak. An innovative way of application login is provided to give a feel of entering an actual vault. Features like Forget password, Search, Swipe to Edit or Delete are provided with no advertisements and is totally free of cost.
Security plays a very important role in emerging technologies and user data should be secured from every possible theft. My father was looking for an application to help him manage his passwords. He was reluctant to use any existing application, which required online storage, or any permission. I took this as a challenge and decided to make an application for him and developed theVault.
theVault is a step towards providing secure storage of user data on the device. It showcases how data can be stored securely on a device and without the use of any permission. While developing, I gained knowledge in using Cypher API to encrypt data on the device. I developed a custom logic that encrypts data differently on different devices and user gesture and has multiple layers of encryptions. I also understood basics of animations that I have used for user login to give a feel of entering into an actual vault.
