PROFESSIONAL EXPERIENCE

Sr C++ Developer

Confidential, New Port Beach, CA

Responsibilities:

• Worked in a team to develop/enhance software to compute income projections, various yields using cash flows for all type of fixed income securities like Treasuries/MUNIs/Corps based off of various characteristics of securities in a portfolio for client accounts.
• Modified C++ programs to support compliance rule automation for a large number of compliance rules for client accounts for both pre and post trade compliance purposes and manage leverage using a large number of metrics like industry exposure, security type, long/short positions, currency / securities / options / futures, credit ratings etc.
• Modified multi-threaded C++ programs to process position / taxlot / transaction data stored in Oracle DB, compute income projections and yields and persist data into DB for current and historical references.
• Used STL containers, algorithms, various data structures and design patterns in software design like Singleton for db connections& Observer pattern for processing events.
• Wrote Oracle stored procedures to compute several metrics like realized/unrealized gain/loss, forex rate effect etc. from historical data taking into account forex rate effect
• Used Python scripts for maintenance tasks
• Migrated from SVN for source control to git, local github.
• Generated various reports ranging from Custom to regulatory reports using Python. Delivered using FTP/email to vendors, regulatory agencies. Used gpg to encrypt the files.

Environment: C, C++, Fortran, Design Patterns, Oracle, Python, bash, ksh, Linux, Threads, complex SQL queries, stored procedures, SVN, git, github, OOAD, BOOST libraries, gdb, Coverity, Jenkins, FIX protocol, Redis, Rabbit MQ.

Programmer/Analyst

Confidential

Responsibilities:

• Distributed application developer for enterprise security master application (SMDB) which provided indicative, pricing and corporate actions data to internal and external customers such as JP Morgan, ING and others.
• Designed, implemented and maintained a multithreaded server that received and processed acknowledgement messages from downstream applications regarding event data pushes using C++, STL, multithreading, shell scripting and UNIX.
• Participated in the development of a multithreaded publish/subscribe process which consisted of several subscription and push servers using C++, STL, multithreading, shell scripting and UNIX.
• Implemented additional rules and logic to provide indicative and corporate actions data to new subscribers by extracting all the required information from data base, generating and pushing messages using C++ and Rogue Wave.
• Implemented a SOAP webservice client program which was used extensively to process and stored in the data base corporate actions data from various vendor feeds using C++ and Rogue Wave.
• Designed and developed a multithreaded process that generated breaks on income events and notified the users when underlying indicative data changed using C++, STL and multithreading.
• Modified existing multithreaded server infrastructure to push additional indicative information to downstream subscribers. Implemented additional validation logic for a rule engine server that checked for logical inconsistencies in indicative data and reported them in a user workflow using C++, STL and multithreading.
• Developed and tested a client that handled the parsing of the municipal bonds feed file and created business objects which were streamed to various servers for data analysis using C++ and STL.
• Created an automated generic archiving utility written in raw DB2 CLI which was used to archive rows from different tables depending on the flag.
