Professional Experience

BioReference Labs, Elmwood Park, New Jersey Jul 2015 – Present Consultant

PwC/Booz & Co, New York, New York Aug 2013 – Jan 2015 Consultant (Remote)


Designed and developed a single-page application website for internal use as part of the Fit for Growth product offering, to analyze and optimize proposed corporate restructurings being undertaken by Booz’s own clients. The data-centric application was written using ASP.NET and MVC 5/Razor, against a Microsoft SQL Server 2012 database, and was designed to make heavy use of jQuery and Knockout.js client-side view models to provide a responsive user interface. The application leverages Tableau Server software to provide enhanced data visualizations on the front end, and interfaces with the FICO Xpress optimization engine to provide cost-effective solutions to clients. Entity Framework 5 was used to manage interactions with the database.

Completely redesigned the previous versions of both the application and the database, to effect not only a sizable reduction in the amount of data being processed, but also a resulting significant improvement in performance and reduction in the technical debt attributable to the original design.


ASME, New York, New York Jul 2012 – Aug 2013 Consultant

CIT Group/Newcourt Credit, Parsippany, New Jersey Aug 1998 – Apr 2000 Consultant


Designed and implemented a distributed architecture for an existing lease origination application. Initial project assignment involved performing performance and architecture improvements to the original application, written in PowerBuilder 6.5 on Windows 95, and deployed against a Sybase 11.x database on UNIX.

Project evolved into re-designing system to support reuse of existing business logic by both PowerBuilder and HTML/ASP (Web) clients. This was accomplished by developing modular business components and deploying them to a Distributed PowerBuilder (DPB) server. ASP access was provided through custom COM bridge objects, written in PowerBuilder and deployed under MTS.



Subsequent deployment effort involved the migration of PowerBuilder clients to Version 7.0, and conversion of the server objects to run under a Sybase Enterprise Application Server (EAServer/Jaguar CTS), using a Delphinus-designed, custom 3-tier application framework. New components were written in Java and deployed to EAServer. ASP pages were modified to directly access EAServer via COM. Migration was undertaken as part of a company-wide effort to establish a uniform middle tier to host common business logic across applications.
