Developer with a experience of 2 years in C, C++, Javascript, Python and Java

I have 3+ years of experience working with Javascript, C, C++, Python, have worked in companies like Salesforce, IIRS ISRO. Have done various projects in fields like Network Programming, Cloud Computing, Systems Programming, Website and Application Development. Some of the projects I have done are Building Storage systems: Cloud computing, SQL queries to map reduce jobs, Compiler Construction, Shell development, Dynamic memory allocator, Tax Management Desktop application.

Some of my projects

Storage System - Cloud Computing

• A storage system for Shopping Cart data, and an API to access the data written purely in Python
• Features developed are Leaderless replication, data partitioning, eventual consistency
• Used CRUSH hash function for mapping, Zookeeper for coordination, read-repair using version vectors for consistency, Flask to build the API

Concurrent TCP webserver - HTTP GET requests

• Implemented a prethreaded webserver supporting HTTP GET requests
• Client requests handled in stages by pool of threads created in the beginning
• All I/O on sockets is nonblocking

Dynamic Allocator - Network Programming

• Implemented a pool dynamic memory allocator in C.
• Allocations are served out of the smallest pool that supports the user’s request, and allocations too large for any memory pool are requested from the OS directly

Spatial data analysis - Website Development

• Developed a website for time series analysis of variation of various available indexes used to analyse vegetation, water level etc using Landsat satellite data
• Supports addition of your own customised indices via a GUI
• Also supports visualizing terrain profile along a path using various available DEMs namely ASTER and SRTM
