Raising twin boys, while doing some trading. Also studying and playing a lot of chess, returning to my main outside interest from my youth. Back then, I represented USA in the World Under-12 Championship, finished 2nd in the national Under-16 Championship and 3rd in the National High School Championship. Also a member of Pressman All-America Team for seven years, and became a national and FIDE Master.

Investor through both Grubstakes and SeaChange Fund. Served as a board member representing SeaChange through Factal's Series A raise.Through a combination of automation and skilled editors, Factal provides real time, actionable news to corporate security teams. I was drawn to the quality of the team and the fact that they started with so much industry demand from their time running a similar service at Breaking News.

Developed and maintained trade routing and execution technology used by banks, brokerages and hedge funds, mostly in C++ and for forex. Wrote the initial version of a plugin API that allowed core functionality to be customized using DLLs. Added a new framework for collecting and analyzing quote and trade data.

I was an investor and active member of the SeaChange Fund (formerly Seattle Angel Fund) for the first six of its annual funds. I greatly enjoyed being involved in all stages of the investment process, from screening to due diligence. I represent the fund on the board of Factal.

Aided the development and launch of a new backend platform and new API. Created a trading bot to test the platform and API both for correctness and scalability.

I started my own stock trading firm, to which I recruited my brother, where we traded our money. The core of the firm was an automated market-making strategy for microcap stocks with very strict risk management. The only money invested was an initial $50K, the maximum exposure to any single stock was $3K, and the total net profit exceeded $3MM.All of the software was written in Java from scratch (including strategy, monitoring, accounting, risk controls, etc.), which allowed us to analyze and optimize the system, in addition to exploring other strategies. The most profitable of those involved OCR (Optical Character Recognition) feeding into an automated trading strategy. Also explored using Alternative Data by developing a framework for crawling ecommerce sites and using it to track daily sales data for a dozen sites.

AMA develops their own software for automated trading in the foreign exchange market. We were always a very small team (for several years I was the only employee), and I had to opportunity to contribute to all aspects of a system that traded billions per day, from developing new strategies to analyzing their results.

Designed and implemented core backend functionality in Java for a startup's data analysis product. Overhauled revisioning code to reduce both runtime and space complexity. Developed a system which enabled federated searches against external data sources, and which propagated changes from the external data sources to our main server. Added group-based access control which supported discovery, read, write, and ownership permissions at the level of individual properties.Designed and implemented a performance testing framework to simulate load and to measure latency and throughput. Re-wrote and optimized many Oracle SQL queries, and improved the database schema, substantially improving query performance. Tracked down and fixed many bugs and performance problems.

Worked on a system that monitored millions of competitor offerings across hundreds of competitors, and that surfaced the data internally through both a service and a website. Revised and rewrote existing C++ services and Perl scripts, and optimized MySQL queries, in several cases improving the running time by more than an order of magnitude. Managed the team for several weeks.Mid-project, became lead developer for a system of web crawlers running in Alexa Internet, Inc. Three weeks after taking over the codebase, delivered critical new functionality. Maintained 70GB MySQL databases in both Alexa and Amazon, including replication, backups, and recovery from hard drive and power failures. Later migrated the Alexa database into Amazon, and integrated the software with Amazon development and deployment platforms.On a project to deliver pre-order price protection, developed a C++ application, wrote SQL queries, and updated Mason code.
