Professional Experience

Bank of America Merrill Lynch, Risk Management Technology, New York, NY
May-05 - present.
VP - Credit Risk Quantitative Developer

Nov 16 - present. A member of Real Time Credit Risk team to maintain and enhance Quartz What-If System: Excel and Wed interface to create and price hypothetical trades (both trade and portfolio level) across all Bank's Credit Risk systems (legacy Credit Studio and newer open source Quartz)


·         Extended Excel functions coverage to IRSwaps (In-Arrears, Compounding, Averaging); Forwards and Option for Commodities; Equity Forwards, Options, and Swaps; Aggregation including Custom Credit Terms: using back-end Python to call C++ Front-office Quantitative library.

Dec 12 – Nov 16. The bank introduced a Python based open source Quartz framework to price trades, manage positions and calculate risk across the organization.


·         One of the original architects and developers of a flexible Aggregation Platform: business requirements for various aggregation types are implemented by dynamically built trees and methods executed while walking these trees.

·         Implemented the core piece of the platform: tree-building subsystem using Python's cElementTree

·         Programmed many important components such as Reference Data loading, Front-office Quantitative library interface, avro-formated output, etc.

·         Designed and implemented a regression test framework, along with a corresponding GUI, that executes any of the Aggregation APIs in Capture mode, to create a baseline of data from any of the tree's nodes-- including the tree itself. Also executes APIs in Verify mode to compare against the previously certified baseline.


Jan 09 – Nov 16. After Bank Of America acquired Merrill Lynch, I moved to work on the combined company flagship Credit Risk System called Credit Studio (CS). It's intended for daily credit risk valuation and aggregation based on a full Monte Carlo simulation. The system has a parallel architecture and runs on a cluster of blade servers.


·         Co-designed and implemented an alternative Credit Risk Valuation platform (UVO – User Valuation Override) that allows the Quants to provide their own valuation formulas (algebraic expressions with predefined variables and embedded functions). This execution environment auto-generates and compiles Java code containing users' formulas to be used during both batch processing and GUI simulation. The platform coexists with the main valuation engine effectively overriding the standard valuation methods when requested

·         Implemented many of UVO's embedded functions such as Black-Scholes-Merton with built-in scenario generation, etc.

·         Designed and co-implemented the next generation of UVOs which allows for multidimensional modeling.

·         Redesigned and implemented analytics for custom Cash Flow instruments: Fees, Swaps (Vanilla, Zero Coupon, Compounding, In-Arrears, Averaging).

May 05 – Jan 09. A member of a Banc of America Securities, LLC team responsible for implementation of a Credit Risk Exposure system called XCalibur and it's real time risk analysis interface called WhatIf.


·         While collaborating closely with the Quant research group, worked on the data loaders and mostly closed-form solutions for many FX Instruments, IRPs, and PBs; FX Barrier Options (calculations based on Black76); Swaps: In-Arrears, Simplified Averaging, FX Linked Floating Notional, Zero Coupon, Vanilla with no Amortization; some Swaps included custom Cash Flows/Fees; Prime Brokerage: Stock, Warrant, Convertible Bond

·         Added a few Financial Functions (Generalized Black-Scholes-Merton for European Options with dividend yield; American Option Approximation with Barone-Adesi, Whaley using a Newton-Raphson Method, Convexity Adjustment, Geometric Brownian Bridge)

·         Designed and implemented so-called "Valuation Overrides" process: the standard valuation formula for a particular Instrument Type is replaced by another formula at the Trade level: a set of Simplified Valuation Functions classes; Execution Framework based on the Java Reflection API; bulk file data loader; Work-flow Web interface for supporting Valuation Overrides with an Audit Trail mechanism implemented as DB triggers; graphical capabilities

·         Wrote an optimization routine for the pack size to minimize blades idling at the end of each run

·         Co-wrote an adapter to invoke the new valuation library from the older real-time risk analysis system (WhatIf)

·         Coordinated overseas contractors on one of the company's portal development projects

·         Designed and implemented an automated Regression Testing Framework for Exposure calculations using JUnit

    Software utilized:
Python, Java (J2EE, including  JSP, JDBC), XML, Hadoop, JavaScript, Ant, Oracle/PLSQL, Sybase, Vignette Application Portal

Applied Information Partners, Inc. Somerset, NJ.
April-98 - May-05.
Technical Leader.


·         Technical management of development teams working on various projects, for pharmaceutical, biotechnology, chemical industries, and nonprofit organizations

·         Designed and developed numerous multi-tier Internet/Intranet information systems using JSP/JavaScript for the user interface, server side Java and Oracle/Sybase/MySQL/Domino R5/R6 in the back-end, and XML for the data exchange

·         Supervised Company's Test Automation effort

The most interesting projects were the following:
- Collection of information systems to track, analyze and budget complex toxicology studies as well as manage Audits for scientific research. The Web interface was a combination of JSPs/JavaScript/Domino Views. MySQL was used as the database. All database queries and calculations such as statistical analysis, dynamically interpreted user-submitted algebraic formulas etc. were coded in server side Java
- Internet/Intranet applications to support Pfizer’ operations. Some of these applications have both Online and Offline versions that use the same code base but work with Weblogic/Oracle and Tomcat/Sybase respectively. WebSevices were used for the data synchronization.
- Web enabled solution for a temporary staffing agency. The agency maintains a database of certified medical professionals. Hospital staffing coordinators post contracts, find qualified nurses, access complete nurse information including scanned documents such as licenses, etc., hire nurses. Meanwhile, nurses constantly update their availability by day/shift, respond to postings, and have full access to their schedule. The Web interface was implemented using JSPs. The main data repository was in Oracle while the workflow application was set up in Domino R5. Matching algorithms, queries and data transfer from Domino to Oracle were programmed in server side Java (servlets, JDBC). Data exchange with related systems was implemented in XML.
- Several implementations of distributed information systems to track minority and women suppliers as well as the Minority Executive Network of TUCK School of Business at Dartmouth . The systems were written in Lotus Domino; data conversion procedures from earlier database implementations were coded mostly in Perl; cross certifications with other tracking systems were written in Perl, Java networking, and XML, and some of the databases were synchronized over the Web using a combination of Notes replication and custom written Java agents.

    Software utilized:
Java (J2EE, including servlets, JSP, JDBC, WebSevices), XML, JavaScript, Oracle/PLSQL, Sybase, Domino/LotusScript, Perl, Crystal Report, Rational Robot

TestNetSoft, LLC. East Brunswick, NJ.
October 02 - present.
Co-founder, Architect and Developer.

The company was established to develop and market a system intended for real-time, redundant, autonomous monitoring of the status of Web applications. The full description of the system, downloads, and list of clients can be found at http://www.TestNetSoft.com


·         Designed and developed the system. The system implementation is based on a distributed Servlet / XML architecture. Testing is performed by a Testing Agent which remotely executes designated Test Pages residing on each Server. The Test Pages are dynamically generated pages such as JSPs, ASPs, etc. that output XML-formatted information to communicate the status of individual services (http, application server, SMTP, JDBC, etc.) back to the monitoring software. Other notable features include a custom XML-based database and its associated replication / synchronization mechanism
