Full-stack Web Developer in Bengaluru, Karnataka, India

UtooChat is a tool for website owners that allows them to add an online chat support system to their websites. Users can sign up and copy code snippets onto their websites to install the service. I worked as a system architect and full stack developer in a team of 4 people. We implemented the presentation website and user logic with Laravel, MySQL, and Twitter Bootstrap. The chat application was created using AngularJS for the front-end, Node.js and Socket.IO for socket and message passing, Laravel for business logic, MongoDB and MySQL to save the chat history and access log, and Redis as a layer between PHP and Socket.IO for the messaging protocol.

Meowfoto is a web-based editor that can apply different types of filters to photos and is integrated with Facebook in order to allow the download of user photos. It also has a collage generator built in HTML5 using KnockoutJS.
Technologies used:
- Custom MVC with PHP and MySQL
- KnockoutJS for front-end collage module (with drag-n-drop)
- Facebook SDK and Graph APIs
- ImageMagick for image processing
- Twitter Bootstrap for front-end design
- Third party Shell scripts for image processing
- Operating system: CentOS 6
Challenges that I faced and how I solved them:
1. Users needed to upload their final collage result to Facebook. The editor worked in HTML markup (using KnockoutJS), which was needed to be converted to image formats like JPEG or PNG. The front-end app exported the JSON data that was processed in the back-end to get the same result. PhantomJS was not an option as it was quite experimental at this time.
2. There were 500+ concurrent users and it was impossible to handle this amount of image processing on a single server. With the help of another system admin, I used the AWS Elastic server with a front load balancer and two clusters to carry out the image processing.

An open source module developed in AngularJS to ease the development process for a file upload component in the front-end. I co-developed it with my teammate and this project grew rapidly with 31 stars and 16 forks.

GW-Basic was the first programming language I came across.
I coded the following programs in my early days:
1. Simple file-based database system to add, delete, and edit items in GW-basic (1996).
2. A command-line program that looked like MS-DOS with commands like DIR, CD, and CLS written in GW-basic (1996).
3. A GUI program that looks like Windows 98 and also has features like a Start menu and Windows with minimize and maximize buttons, written in C (1999).
4. A personality assessment web-based program written in HTML, PHP, and MySQL (2000).

A website built with WordPress and WooCommerce. I worked with a team of 3 where my role was to architect and code few sections of the website. I hooked into the WooCommerce framework and added a pre-checkout page to list few questions. The answers were collected from the user and were then presented to the doctor's login account, which was then forwarded to the pharmacy account for actual shipping and post-processing.
