PROFESSIONAL

EXPERIENCE

Merrill Lynch – New York, NY, USA

Mar 2006 – Feb 2008

Vice President, Equities Trading Technology.

Merrill Lynch is one of the world's leading wealth

management, capital markets and advisory companies, with offices in

38 countries and territories and total client assets of almost $2

trillion.

Technologies: C++, TCP sockets, multithreading,

boost, ACE, RedHat linux, Windows XP, Solaris, Berkeley DB, Oracle,

TIBCO Rendezvous and EMS, ultra-low latency systems.

Worked on the core infrastructure of the Market

Access product that connects Merrill Lynch to the financial

exchanges of the world (e.g. NYSQ, NASDAQ, LSE, etc). Specialized

in efficiency tuning and product design.

The Market Access product has a guarantee of less

than 1 millisecond latency in a single direction, which must include

logging, updating internal state, persistence to a permanent storage

device, and translation to/from the exchange-specific protocols in

question.

Created a replacement for the log4cxx logger that

allowed us to log messages 4 times faster than log4cxx without any

more exposure to loss of data. Later tuned this to allow for

asynchronous logging with a memory map backup which was even faster

and also guaranteed no lost log messages.

Created an innovative distributed cache (DC)

system back by Berkeley DB. This system was fully transactional and

used customized smart pointers that would conditionally commit data

(if it had been modified) to a transaction when it was no longer

referenced, and transactions that would automatically commit when

they went out of scope. Both were exception aware and thread safe.

Created a full-featured regression testing tool

capable of replaying a full day's production data in about an hour.

Could handle multiple applications, multiple connections to each

application, and validated all data received using regular

expressions. Had special code to handle stateful sessions, and also

handled things such as fields that were dynamically created by the

application(s) being tested.

Team lead for a group of 5 developers.

CodeStreet, LLC – New York, NY, USA

Oct 2005 – Jan 2006

Senior Developer.

CodeStreet provides business-critical trading systems

and software infrastructure for the financial services industry.

CodeStreet both creates their own software and provides high-quality

consulting services.

Technologies: C++, multithreading, boost, RedHat

Linux, Windows XP, Solaris, Microsoft SQL, TIBCO Rendezvous, Reuters

Market Data System.

Ported a windows-only tool that enabled data from

the primary data store of a ReplayService (including both

ReplayService for Rendezvous and ReplayService for RMDS) into a

comma-separated value or SQL database (via. ODBC) to Linux and

Solaris (while retaining Windows support).

Overpeer, Inc – New York, NY, USA

Oct 2002 – Oct 2005

Senior Software Engineer/Architect.

Overpeer, a LoudEye company was the industry leader in

peer-to-peer content protection and marketing. Overpeer was

successful in both making it harder to find illegal content on

peer-to-peer networks, but also in providing clients the valuable

opportunity to market their products directly to their customers by

delivering digitally rights managed content.

Technologies: C++, multithreading, TCP & UDP

sockets, Gentoo Linux, Windows 2000 & 2003, Berkeley DB,

Microsoft SQL.

Designed and implemented the primary data-driven

infrastructure (including DB schema, middleware and internet-facing

applications) that were the core of Overpeer's business.

The internet-facing application communicated to

five different peer-to-peer protocols simultaneously. It handled

more than 50,000 new connections every minute and sustained between

10-15,000 simultaneous file transfers at any time per instance of

the application.

Created a Store and Forward system to ensure that

all the details of peer-to-peer activity would not be lost. Also

created systems to allow for per-file and application-wide

throttling (to conserve bandwidth) and to ensure that nothing was

I/O bound (so the CPU and RAM could be utilized to their fullest).

Scaled the operation from less than 30

internet-facing hosts to more than 650, at our peek we were

sustaining more than 6 gigabit/second with bursts up to 8-10

gigabit/second.

Created an independent tool to accurately check

the actual effectiveness of the internet-facing product. It acted

just like a peer-to-peer client and would search for content we were

protecting and could distinguish between content we were hosting,

content our competitors were hosting, our own content that was being

shared by other users and actual piracy.

MicroMuse, Inc – Pleasantville, NY, USA

Feb 2001 – Jul 2002

Senior Associate Engineer.

Micromuse is the industry leader in network assurance

applications. It provides network management and predictive fault

analysis products to ensure rapid (even pre-emptive) resolution to

potential network problems.

Technologies: C++, Java, multithreading, Linux,

AIX, HP-UX, Solaris, Windows NT, Perl.

MasterCard International – Sydney, NSW,

Australia

Jul 1998 – Nov 2000

Software Engineer.

MasterCard's Regional Processing Center (RPC) in

Australia was the first of seven such centers designed to simplify

and modernize the existing processing network MasterCard uses for all

credit and debit card authorizations. It removes the need for each

credit/debit card issuer to have specialized hardware provided by

MasterCard, allows MasterCard more transaction control and reduces

infrastructure complexity by having seven main regional hubs as

opposed to over 600 individual nodes in a virtual private network.

Technologies: C, IPCs, Solaris, Oracle and

Pro*C, Perl.

PERSONAL

EXPERIENCE

Mantra

http://www.neuromancy.net/mantra

Mantra is an application framework designed to allow

client developers to just write their business logic and not have to

worry about re-inventing the common infrastructure elements most

large applications need such as multi-threading, data storage and

message routing.

Mantra is designed to allow an application to have 100%

uptime by dynamically allowing individual modules to be loaded and

unloaded runtime, and do things such as re-route message flow to a

new module and away from old modules in real-time.

Mantra also plans to support things such as clustering

and load balancing between different processes and even different

hosts, tight data binding (including transactional support) with a

universal storage interface supporting multiple data storage

back-ends, and much more.

Mantra is still under development and has yet to

release official revisions of this product.

Magick IRC Services

http://www.neuromancy.net/magick

Magick is designed to provide Internet Relay Chat (IRC)

networks with services that allow for more control over the network.

These services include things such as nickname registration, channel

registration and control and IRC operator controls (for doing things

such as global bans or restricting 'clone' users).

Magck was also the first IRC services product that

supported Direct Client to Client (DCC) file transfers, which allows

for things such as attachments on memos between users, a user to

store a picture in their nickname profile and a file system

controlled by the services administrators for public downloads.

Magick started its life as a fork from the ircservices

product by Andrew Church in 1996, and quickly became popular. Magick

II was released in 2003 as a complete re-write in C++ incorporating

multi-threading and many other advanced improvements. Magick III

will be written in terms of Mantra when it is released.

GOTH.NET

http://www.goth.net

GOTH.NET is a community portal for the worldwide Gothic

community. It has been in operation since 1997 and provides a large

variety of services including an online forum (with over 5000

members), e-mail and web space accounts (more than 2000), Jabber IM

accounts and a comprehensive on-line links database.

As owner and systems administrator I am responsible for

ensuring the system hardware is sufficient for the tasks at hand and

the software is both up-to-date and configured correctly. The entire

system is database based (including user accounts, quotas and

DNS/domain management) and I wrote several custom perl scripts and

modules for system administration.
