Refocus- Contributed in implementation of Refocus - The Go-To Platform for Visualizing real time streaming events.Implemented and improved performance of REST APIs to accommodate increasing scale of the platform. - Implemented unified error handling, caching middleware to increase reliability and availability of the platform.Implemented distributed in-memory data store architecture to process ~20 million real time events per hour.- Designed and developed configurable collector system to automate the process of gathering data from any source and push to Refocus.- Implemented scalable buffered queue to reduce overhead by giving more control to clients for receiving events.- Developed Refocus API client/wrapper using Python so that people can use Refocus APIs very easily.Trust - Working on the backend for Trust platform which provides service availability and performance status of Salesforce infrastructure.- Achieved 90% performance improvement in REST APIs which involved: caching mechanism, read - write DB structure, worker process architecture. Also, removed unnecessary overhead in computations/joins and modified schemas.- Proposed and staged a new architecture of Trust 3.0 project to scale further and accommodate all infrastructural changes and merge new acquisitions of Salesforce in the project.- Integrated Trust platform with Salesforce Authentication Open ID and developed JWT based authentication mechanism for APIs.- Decoupled certain segments of code from monolithic code base like notification delivery, auth system and converted into micro services.- Designed pipelines on Heroku and Docker Kubernetes to deploy and ship the project in any cloud environment like AWS, GCP etc.

● Working with Platform / Infrastructure team and currently working on project named Refocus - The Go-to platform for Visualizing Service Health which is now become Open Source. https://goo.gl/sJBB3Q● Implemented various REST APIs, improved performance of APIs, fixed few broken APIs, implemented unified error handling at API layer, added some new features and fixed many bugs related to the project.● Implemented automatic migrations schema, one click Heroku installation and code coverage for the project.● Designed and developed sync tool to maintain up to date mapping of servers in Refocus for Salesforce.● Developed Refocus API client / wrapper in Python so that people can use Refocus APIs very easily.

I was grader of graduate course : Data Structure and Algorithm ( 16:332:573 )

● Worked on BackEnd as well as developed Game Engine for multiplayer online card game portal    named “TajRummy” using Python (Django + Twisted).● Designed various AI procedures and algorithms to create Bot that can play with the original player    as well as auto play mode of the game● Developed Tournament Architecture for the same platform● Developed network architecture of TajRummy where people from different domain can play    together on single platform.

● I was mentor for Wikimedia Foundation for Program Google Code In.● I assigned few task to students who's age is between 13 to 17 years and mentored them to solve    bugs and add some small features.

● Working on the Language Coverage Matrix Dashboard project for the Language Engineering    Team of Wikimedia Foundation● This web-based application automates all the information that are available on the Language    related topics that Wikipedia and its Sister project covers – tools they support, languages they    have support for, statistics that are available for public use etc.● Developed data visualisation and analysis framework● Designed API to use this entire details for third party ● Technology used : Php, Python, JavaScript, CSS, MySQL, HTML5

● Developed Genetic Algorithm Based Digital Filter for adaptive filter responses under the guidance    of Dr. Y. B. Acharya● Designed customized application layer, called the Filter Design Algorithm (FDA) using optimised    Genetic Algorithm to handle the specific format and properties of the filter design problem using    MATLAB. ● After developing FDA, implemented Digital Filter using VHDL.
