Esper Foundation for Android
Esper Foundation for Android is the leading enterprise solution for custom Android builds on dedicated devices. Regardless of whether your hardware is running ARM or x86 chipsets, Foundation is the most flexible, robust, and secure option you can get. It's the power and versatility of Android, customized and optimized for your purpose-built devices. If you can dream it, you can do it with Foundation.
I worked as the lead engineer on this project.

This is the core which is in constant sync with Esper Cloud and empowers management and control of devices by performing necessary actions.
I worked as one of the lead and founding engineers on this project.

I mainly looked into the bootloader stack (named kernel flinger).
Android Open Source Project (AOSP)
This is the global open source project aimed at developing the Android Operating System.
Android-x86 Project
Porting Android to x86 architecture
PacketZoom Mobile Connect
Gaming and multi user communication made easy. Mobile Connect provided real-time multiuser communication by leveraging PacketZoom's proprietary network stack, mature mobile SDK and hundreds of globally deployed servers.
I worked as the lead engineer on this project.
PacketZoom Mobile Express Lane
The PacketZoom Mobile Expresslane was an in-app networking solution customized for each end user. By using our own homegrown transport layer protocol, we were able to significantly accelerate the network performance by 2x to 3x.
I worked as the lead engineer on this project.
PacketZoom Mobile IQ
Real-Time Mobile APM (Application Performance Monitoring) Solution. Empowered mobile app developers to analyze and control application behavior across all networks and geographies in real time.
I worked as the lead engineer on this project.
Elementary OS (open source contribution)
A user friendly and visually appealing desktop linux distribution.
I made some contributions to the login manager and adaptation of the pantheon desktop environment to arch linux.
Personal Projects
EasyShare (personal project)
A network file sharing tool written in Core Java. It shares files via TCP and has been designed with great care to not to introduce any extra overheads over TCP.
UI is written in JavaFX and great care has been taken to keep it light and simple. At the time of transfer, all necessary details like size, percent, ETA etc. are provided.
Can be used on any Java J2SE enabled operating system.
HttpX (personal project)
A very light weight Web Server API in Core Java. Provides very basic features. Highly extensible and flexible.
LibJson (personal project)
Very flexible, lightweight (~8KiB) and simple to use JSON library for Java. Supports conversion of Java Objects into JSON.
LittleRAT (personal project)
Remote Access Tool written in Java. It provides screen monitoring with multi-touch gestures and keyboard controls, file management with read, write and execute features, shell access, task management and many other features.
Cafebabe (personal project)
A JAR to native package converter written in Java and C++. Protects the Java byte codes by encrypting and packing them into native packages. Uses JNI to instantiate JVM and forward the byte codes in a secure manner. This adds an extra layer of protection to reverse engineering attempts for proprietary code.
JNetSpy (personal project)
ARP Spoofing based Man-In-The-Middle attacker written in Java and C++. It can monitor network traffic between two nodes in local network.
JNetCut (personal project)
ARP Cache Poisoning based network jammer. Basically, the packets between Router/Gateway and the target nodes are routed to a non-existing address at data-link layer.
