I have seen android grow from Android 2.0 to Latest 8.0.  Over the years i have developed many apps for android and have implemented most of the features offered by the platform in some app or the other. 
I have detailed knowledge and experience in 
- Android APIs,
- all the android tools such as Data binding, Kotlin, Dagger, Android Architecture Components, Gradle, Android studio etc
- improving performance of the app by using various android profilers, method tracing, cpu and memory monitors
- app testing: have written good amount of espresso and ui automator test to automate the testing process of the app
- code generators and libraries: have written few code generators to decrease the amount of boiler plate code and ease up the development process

From the last 3.5 years I have been working with directi in building flock Android(an enterprise messaging app). Have worked on 
- building a great platform for flock using many microservices which are being hosted on AWS infra.
- migrated the android's legacy monolithic codebase to micro services
- performance optimizations: have worked on optimizing a lot of flows in the app to improve the over all user's experience using a lot of custom made android tools to measure and monitor the performance

Have been developed quite a lot of android apps for many companies, here are few of the app published on play store

Javascript is really a versatile language and is being used almost everywhere. I have worked on both serverside JS (node, express) ,frontend JS frameworks (Angular) and few JS tools like hubot built on coffeescript.
Have even worked at Google as an intern for 3 months building there JS framework using google closure library and JAVA apps framework to built a tool to visualize user's behaviour on various google pages in the form of heatmaps.


I frequently participate of various coding competition websites like TopCoder, Codeforces, Codechef. I have spent uncountable hours in learning and practicing algorithms and because of this I have won many contests. I even qualified from India for participation in ACM-ICPC world finals (Olympics of programming) in 2014 which was held at Ekaterinburg, Russia as a part of the TEAM Moduli.

Have over 1 year of experience working with docker. I use it extensively to host my various server environments and version. I believe docker containers are the best way to host servers as they can run and can be moved to any unix based system without any extra effort.

I am a big fan of git and have been using this for ages for version control. Have also  taken many Git training sessions at Directi as a part of new hires training program. 

I use python as my go to scripting and prototyping language. Have written many tools and scripts on python. Have also build many serverside apps on python frameworks flask and django.

Have over 6 years of experience building products and solving complex algorithmic problems in c++. It is my goto language of choice when competing on  an online competitive programming platform.

Combined both approaches of content-based and collaborative filtering to build a
hybrid system which recommends movies to a user and also finds out genre indices
for the movie that is how well it ranks on a scale in the genre of comedy, drama,
action etc.

Movie recommendation System using Collaborative Filtering

Developed a system to solve the camera interoperability problem in Iris recognition.
Created the feature set for iris images using OpenCV and integro differential operators, and classified the iris images using a multi layered machine learning algorithm made up of Support vector machines, Naive Bayes and Adaboost ensemble method.

Iris Camera image interoperability Classifier

Developed a web app to analyse tweets related to some topic, and generate some interesting data related to the same.
