• Primarily involved in requirement analysis/design/coding/unit testing for enhancements and defect fixes for existing windows based device driver.• The project works in onshore/offshore model and I’m currently also working as onshore coordinator for the project which entails engaging the client and offshore development team in solving bugs and creating new enhancement and also requires mentoring and monitoring skills.• The system is highly complex code with millions of lines of code and is multi-threaded with 2 independent processors which require coordination/synchronization in the code.• Implemented state machines, IOCTL processing, writing debug functions (in winDBG extension DLLs) for enhancing debug-ability, command line interface for the user to issue various commands for debugging and other purposes.• Enhanced existing hot sparing and proactive sparing functionality.• Performed Crash Dump analysis for debugging the problems in the device driver.• Created sequence and state diagrams using Enterprise Architect software for new development.• Involved in driver bringup activities on hardware

I worked on modifying firmware of client device for calibrating and communicating with field instruments (like temperature, pressure and volume transmitters) as per HART standard.Implemented six sigma tools for project (namely SIPOC, process map, C&E matrix, etc.)Tools used were IAR embedded workbench (target was motorola processor) and language used was C.

CISAAs the name suggests, this project acts as a platform for variety of applications providing them with charging data and auditing the output. CISA platform has developed its own pricing engine for pricing various kinds of call records, considering many factors in order to make sure that live pricing engine is using correct data.• Performing RCA (Root Cause Analysis).• Creating Low Level Design for change request.• Coding as per design document and code review.• Performing PCA (Physical Component Check).

Celetron Failure Analysis (CFA)This program analyses and decides which bits to recover in a chip depending upon analysis of failures and spares available. For this 256 MB good DIMM is used in first slot and then chips on adapter board is placed in second slot for purpose of analysis. Implemented optimization of CFA for DDR in Celetron SriLanka, which increased the yield of production by many folds.Received appreciation of work done in CFA as well as other projects from C.T.O. (Memory) of Celetron Mr. Chuck Peddle (Creator of first microprocessor of Motorola 6800 series)• Participated in design discussions.• Coding for various parts of CFA.• Testing of program using SDR/DDR chips.

GetWorksheet.com and MakeWorksheet.comThis project was aimed at providing useful and valuable repository of code and scripts online at reasonable prices. PHP was used as a scripting language to develop front-end application and MySQL as a backend• Implementing module responsible for storing and managing scripts on server.• Implementing online transaction processing using payment gateway provided by ipaymenttechnologies.com

E-mail ClientThis e-mail system helps user compose as well as receive various MIME messages. This system allows facility to store attachments online so that they can be resent anytime from anywhere.• Coding front-end of the system.• Creating module, which implements various rules for filtering of mails.• Understanding POP and SMTP protocol and MIME message format
