Responsibilities:

• Continuing Engineering for Healthcare products. Solved many problems in complicated legacy C++ code, including multithreading, COM, performance, crashes
• Implemented Dragon support for new control from Meditech
• Showed the company how to diagnose memory leaks by using UMDH
• Found and solved a showstopper bug that QA had missed, tracked the cause down to a mistake checked in three years previously.

Responsibilities:

• Implemented privacy - preserving, error-tolerant DNA matching using homomorphic encryption and a variant of the GMP computation library
• Added new features (mIRC support) to Lariat, a testbed implementing a model of the internet so that security-related experiments can be carried out.

Consultant

Confidential, Lowell, MA

Technologies: C++, STL, MFC

Responsibilities:

• Troubleshooting problems on legacy code written in VC6 to monitor medical catheter procedures for treating heart arrythmias.
• Solved multiple showstopper bugs that the rest of the team had been unable to solve for months.
• Making changes to improve stability of old, badly-designed code with multiple threading and memory corruption problems and make it much more useful in treating patients.

Principal Software Engineer

Confidential, Nashua, NH

Technologies: C++, STL, SQL Server, VMware, ClearQuest, ClearCase, UMDH, Windbg, Fortify

Responsibilities:

• Lead developer on effort to improve security of code base by making changes to remove most important causes of security breaches.
• Maintained legacy code, troubleshooting very difficult problems .
• Created custom binaries to run at customer sites to gather more information.
• Used VMware daily to set up multiple-machine environments to troubleshoot problems.
• Solved muliple-thread problems occurring in multiple-processor servers under heavy load.
• Introduced UMDH to co-workers, showed how to use it to solve memory leaks; found problems in Microsoft code.

Consultant

Confidential, Boston, MA

Technologies: C++, STL, SQL Server, cryptography, SmartCards, SecurID tokens, VMWare, Java

Responsibilities:

• Developed Gina analysis tool for use by field engineers and sales force.
• Analyzed problems of integrating RSA implementation of PKCS11 standard SmartCard protocol with MyID product by Intercede, located areas that will need further negotiation between the 2 companies, and also located a problem in how RSA was writing objects to SmartCards.
• Worked on SecurID token project to restore a used token to initial state so companies can recycle tokens that once belonged to departed employees.
• This involves low-level communication with the token, installing correct Java applets.
• Solved GUI problem of interaction of 3rd-party product with RSA Gina 3rd-party password policy enforcement policy would work with RSA Sign-On Manager.

Senior Software Developer

Confidential, Boston, MA

Technologies: C++, MFC, ATL, STL, COM, DCOM, VB6, SQL Server, ASP, JavaScript, VBScript, Visual Studio 5, Visual Studio 6, Visual Studio 7, Visual Interdev, Windows 2000, Windows 4.0, BoundsChecker

Responsibilities:

• Designed and implemented a console application to communicate with Elm site, retrieve student loan queries, communicate with main ASA system via COM, send reply to ELM site.
• Designed and implemented code to come up with a payment plan for defaulted borrowers, taking into account multiple loans, varying interest rates, and various other charges. I wrote the specification (there was none), and got approval from the analysts.
• Designed and implemented code to work with a web page to support litigation steps. This included setting up events to occur on future days, and a clean way to specify the steps that could be taken from any stage and to populate the web page accordingly.
• Designed and implemented better database schema update code (a web-based utility). The old code was very slow, my redesigned code ran 10 times faster.
• Designed and implemented high-level code to pull credit reports.
• Reimplemented ASA build system, made it much easier to understand, mae it controllable from other machines.
• Solved the problem of making production code work in release mode. Previously, production code was run in debug mode, they didn’t know how to make release mode work. I solved the problems, the result was that production ran twice as fast.
• Moved source code from building under Visual Studio 5 to building under Visual Studio 6, made necessary adjustments in code.
• Performed extensive maintenance and troubleshooting on the main ASA system, a transaction-based financial system to handle student loans.
