Sr. Software Engineer

Responsibilities:

• Design and develop complex Operation Research decision support models/applications using the existing Inventory management system infrastructure and architecture to achieve the faster processing of the huge data using orchestrate threads. Defining the actual logic for each component of the system and then developing proficient algorithms for the Project.
• Analyse Orion/Gemini data/datasets and collecting sample data for replicating the same environment in the development area of Solaris/AIX-UNIX/HP-UX/Linux-Test and Production server. Replicating all jobs, binaries, scripts and opds on the AIX/Linux-test integration server area.
• Architect solution for data backup, contributed in IBM DataStage, Oracle & APS (libraries) fine-tuning and configuration of the ORION/Gemini Servers.
• Responsible for Architecture Design, High Level Design, Low Level Design, incorporating the complex decision support models by studying systems flow, data usage, work processes and investigating problem areas. Also, responsible for the designing the advance ANSI SQL and PL/SQL queries, procedure, cursors, views, tables, triggers, multi-table joins, sqlca struct (specific to error handling) for the database.
• Develop C/C++ modules for parallel distributed processing based system written predominantly in Shell and C/C++ running on Solaris/AIX UNIX/HP-UX/Red hat Linux server. System consists of approximately 100,000 lines of Korn shell and 300,000 lines of C/C++. This code processes Fare, Availability and Demand information, controls publishing and copying to ORACLE databases, and performs pricing and aggregation of data for GDS-EDW systems.
• Design most complex and intricate proficient algorithms for the various enhancement like Flight Specific Breakpoint, ACE, NetOpt, Preview, TOD etc.
• Develop software solutions by C, Orchestrate, C++, shell scripting, Awk, Sed, IBM Datastage, Python, GCC tool, GNU make, Purifyplus tool (purify, quantify and purecov), Cplex optimization tool, PL/SQL, ftp/sftp, esql/c, pro*c, SQL, Netica, topas and java for the various components of the ORION/Gemini projects according to the low-level design. Also, creating, modifying, maintaining and optimizing MS APS/Oracle 10g/Informix 4GL/SQL server database.
• Developed the modules on the C++ (BOOST Libraries, Threading, Data structures (Linked lists, Trees etc.) environments).
• Coordinate and monitor onsite & offshore development team.
• Responsible for Unit and System Testing of all components of the project using insure++, Purifyplus, xldb, idebug, DDD and GDB debugger.
• Custom user training, performing periodic system updates, writing documentations to describe program development, logic coding and corrections, interacting with users for future enhancements for the project.
• Developed the Pro*C code to connect the Oracle/Informix for the Preview-GUI for user interaction directly to the database.
• Maintain the source code repository for the Gemini/Orion projects on RCS and GIT system. Also, attending the user review meeting to accommodate the changing scope if required for the Orion/Gemini project.
• Developed C/C++ software to utilize Thread Building Blocks (TBB) library from IBM Data stage/Orchestrate. Optimizing usage of hash tables and maps using concurrent components. At the same time writing programs using the IBM ILOG CPLEX Optimization tool.
• Monitor the Orion/Gemini job cycle with enterprise control system tools for production support issue solving.
• Coordinate with onsite Program Head for all deliveries with proper documentation and solid understanding of the software development life cycle processes. Also, prepare the project status and quality reports on weekly basis for the projects and ensuring overall product quality.
