I'm currently a Senior Software Engineer - 1 Software Development Engineer in Test at Commvault India Pvt. Ltd.

I have Masters degrees from University of Nottingham, UK, and St. Xavier's College, Kolkata, and a BSc from Scottish Church College, Kolkata, all in Computer Science.

For more details, take a look at my CV.

In the past, I've worked with startups and on research projects, mainly with a group at Yale.

My primary area of expertise is in cloud based analytics and in end to end infrastructure engineering for cloud servers used for IoT projects. I have designed, developed and implemented cloud based message passing, file transfer, and encryption APIs. I am proficient in embedded programming using the Arduino and the Raspberry Pi. I'm also interested in Home Automation and Computer Architecture.

I am a passionate programmer and writer. I have reasonably strong opinions about politics, enjoy constructive debates about philosophy, and have an insatiable appetite for non-veg cuisine.

Projects I've worked on

Blackbox

Blackbox

An automatic backup making software for USB devices. The user may have multiple USBs to backup multiple folders. The software may run in parallel while the user changes the contents of the selected folders. All folder backups are made consistent as long as the software is running. This software was built by myself along with Debayan Gupta under Prof. Avi Silberschatz.

Oculus

Oculus Server-Client

This is a boiler plate design for a generic TCP/IP based client-server arrangement. The clients may authenticate and connect to the server using a specific set of API calls. This design allows the developer to create his own API with minimal change to the rest of the code. This client server arrangement can be used for building chat messengers, file transfer systems and many more.

Oculus Raspberry Pi

Oculus Raspberry Pi Client

This is a Java based client specifically tailored to communicate with the Oculus Server when running off a Raspberry Pi. This client has a boiler plate design with GPIO library based functions that may be called as per user input. This client is primarily used for robotics, drones and home automation.

Optix

The OpTix Project

OpTix is an innovative, data-driven technology that maximizes Seat Occupancy + Profits for movie theaters. OpTix is a cloud-based enterprise product. The OpTix algorithm employs a powerful artificial intelligence based technology that dives deep into the granular data of consumers in order to predict future buyer patterns, maximize customer lifetime value, and automatically generate dynamic, data-driven marketing strategies. The official website is available here.

Perch

Perch

A dock for storing frequently used softwares which may be deployed either by clicking on them or by using hotkeys. Softwares may start in a particular sequence or based on events like timers or on startup. The online version of of this dock has an additional feature using which applications may be deployed remotely by communicating with the Oculus-Server using an Oculus standard compliant client. This is a freeware and more details may be found here in the official website.

Pensieve

Pensieve

A secure software designed to act as a personal diary. Each entry is AES encrypted using a key file which the user can store separately. The Pensieve may connect to the Oculus Server for securely storing the encrypted text and keys. This also allows text retrieval from other Pensieve clients.
