Work Experience:

Project : Sierra

Company : Lightning Storm Software

Duration : September 09 - May 10

I was doing a volunteer job for the startup company called "Lightning Storm

Software", which is developing a new language named "Sierra"(coded in C) -

high level C or in other terms, Readable C.

Sierra is a layer above C in which code is described in human terms, mainly

designed to simplify, speed up programming and to reduce the complexity. It

focuses on reuse and avoiding the cryptic code. Sierra is designed to be

able to write code based on how humans think.

It has less strict rules and has implied meanings. Sierra functions are

more readable and Error checking is implicit. Data structures (Linked list,

BST are pre-implemented.

Responsibilities:

Designed the C base code of Sierra translator.

Involved in grammar generation of Sierra.

Involved in Design of Function Spec of Sierra.

Involved in design of Sierra manual.

Implemented Linked lists,loops, conditional statements, switch,

input/output statements, comment handling, arrays, strings, functions, file

operations in C version of Sierra translator.

Code review,Unit testing and module testing of the above mentioned modules.

Involved in development of GAE (Google App Engine) version of Sierra

translator.
