Founder And Partner

San Francisco, Ca, Us

The Giant Pixel was different than your average startup. We were building multiple projects that we hoped to spin off into their own companies. Our goal was to find people who are not just talented, but also entrepreneurial who will work on the projects and then be part of the founding team when we spin off the company. We shared experience, code, design and our office so we can get to making great products, and rebuilding the wheel to get things started. Our partners have founded and ran Yammer, Xoom, Geni and Eventbrite.I wrote a large portion of the backends of our projects, our reusable library of ruby gems, our release tools and brought my style of project management to the team.We ended with a few projects:Antenna http://anten.na - Personalized news and talk radio for your commute, workout and on-the-goNama http://namapm.com - Achieve project nirvanaSuccessful projects through transparency, feedback, and real-time communicationSoBo - The Social Soundboard, a social experience app based around audio.

Nama was modern project management with real-time messaging. As your team collaborates, messages are tied directly to your project or tasks, where they belong. No more using third party tools only to have information fall through the cracks.Nama uses instant feedback and a "no surprises" design philosophy to keep your entire organization up to date about what is – and is not – progressing in your project.With an emphasis on prioritization and communication, everyone always knows the most important thing to be working on at any given moment. In our experience, this is the only way to align teams with business goals.Nama is a beautifully designed, SaaS solution – free to join, and teams get up and running in minutes.

I was brought on at GameLayers to take over the CTO position from one of the founders. While there we made a change from a toolbar based MMO (PMOG) game that couldn't find revenue to developing facebook games. With 2 other engineers and 2 creative, we were able to get DictatorWars out the door in 9 weeks, architected by me such that we were able to get our next game Super Cute Zoo out in 4 weeks. The system here was a Ruby on Rails backend, XHTML/CSS/jQuery on the frontend. During that time I also moved our existing game completely over to Amazon EC2/EBS/ELB in about 3 days.What I did:Helped run the company with the 2 remaining foundersLed development of the new facebook gamesArchitected the underlying game engine to allow for easy skinning and rule changes.Hands on I built everything from payment processing to stats, optimized the backend, added a caching layer, facebook and twitter integration, etc.Also created our development system and configuration, managed the database, backups, staging system and live system. Generally did all the ops work.I ran the day to day project management of the entire team in getting the games out the door, handling requests and bugs, and prioritizing our ongoing tasks.

Doostang was written by a team of 15 in Russia. Delivery was too long, features were hit or miss, so the founders wanted to bring engineering local - so they hired me. With 6 engineers, we brought out a site in 3.5 months (released exactly on planned date), from an MS/SQLServer/ASP/C/.Net lbase to Ruby on Rails (with some Java/Lucene/Solr). Post launch ran product and engineering planning and scheduling, getting the team on a 2 week sprint, being more agile with more feedback.Besides managing, I was coding all the way. Helping the Russian team with ASP/.Net/C problems, I added a separate Python layer with SQLAlchemy and Elixir to add an ActiveRecord equivalent so I could add extra functionality to the site without waiting for the Russian team, including a method for filtering and validating outgoing invitations. Later, added the RoR framework, the dev build system (nginx, RoR, third party software), MySQL, and worked on pieces including the mail system and the admin/back office.

Hands-on manager and lead of the backend document analytics system. System was a home-grown distributed grid, analyzing documents from all over the electronic world (web, closed caption feeds, monthly magazine edumps). When I joined the company's system was capable of analyzing ~15,000 documents a day with 6 machines. When I left, the grid was doing upwards of millions of documents a day, and had an archive of 100,000,000 documents. This included everything from crawling the web, parsing documents, third party integrations, internal analyzers, data-warehousing, terabytes of storage, and internationlization.

Tiny company of past-game industry folks trying to build a DirectX equivalent for hand held devices and cell phones. A few years too soon. Company ran out of cash.

Lead X Engineer

Brio Technology

Back in the day I knew more about the X Window System then most people could dream of. With my experience in cross platform architecture at Wolfram Research, I jumped into Brio's multi-platform team (ok, the team was 2 people, my manager and a contractor) and took over the unix version. I brought the code up to speed with the C++ spec, ported it to linux for fun, and took over all the reigns of both the Unix and Windows version after about 6 months. Also reworked the graphics and file subsystems so the application's group could have an easier time with graphical objects, windows, pens, colors, etc..Also helped the other teams in debugging both windows and unix issues, the main application, and just about anything else. Everything here was in C++.
