I am good in handling any project related to web or app development, but my core competence lies in Android.
Being a developer I love to solve real life problems by using the stacks I am comfortable with and it feels great when people use your applications, because at the end of the day Its all about affecting people's life in a positive way.
The project I have invested most of my time in is CLAY.
CLAY is a location based social network applications that lets you connect to people, places and events near you.
Being a full-fledged social network application it has tons of frontend and backend codes. So, my biggest challenge was to manage the code properly and writing clean and reusable codes and I got better and better with these things throughout the course of the project.
