Brian Helfrich has more than 15 years of experience in computer technology research and development. He's currently Chief Architect at Helcorp Interactive, a game company in Seattle developing a real-world spy game. Prior to Helcorp, he worked at Amazon as a Software Development Manager in the Amazon Android Appstore where he managed the development and operations of services in support of the Kindle Fire and Android mobile devices. Prior to the Appstore, he managed the development of Amazon's EC2 Spot Instances, a spot market for selling cloud computing resources. Before landing at Amazon, he served in multiple technology leadership roles in high-tech startup and R&D companies in a variety of industries including social media, search, computational nanotechnology, speech recognition, and marketing. Brian started his career at Telcordia Technologies (formerly Bellcore Labs) where he was a Research Scientist working on automated speech recognition applications, visualization of complex systems, and new business development. Brian holds a BA degree in Computer Science from UC Berkeley. He has three patents, including the patent for the pricing algorithm used in Amazon's EC2 Spot Market.

system for computer instances and software
- A combination of EC2 control scripts, Chef, Nagios, and Ganglia packages
- Designed and implemented an agent-based distributed computing system used to
process and store over 100 million documents producing over 400 million objects
(text files, images, and PDFs) consuming 100 terabytes of storage.
- The system continually ingests raw data from various sources ranging from tapes sent from the US patent office to live press release data pushed to collection points.
- The system's agents are fully scriptable and operate in an environment providing text processing, graphics, OCR, named entity recognition, and natural language processing services.
- The system runs on Amazon Web Services with load-sensitive dynamic resource provisioning for efficient utilization of pay-per-hour compute instances.
- Created "Boliven Web Services" comprising
- A set of web services providing RESTful API access to Boliven's data for use internally, and externally on a pay-per-call basis.
- A set of widgets (patent search/PDF boxes, patent drawings scrollboxes, scrolling data feeds) and RSS feeds used to syndicate Boliven's data and functionality to external sites.
- Coordinated the design and execution of a system to pre-calculate the social network of people implied by their appearances on over 100 million documents.
- Created and managed a project to find failure modes for 25 published carbon-
dimer mechanosynthesis tooltips. Implemented a ~10,000 node, globally dis-
tributed computing network to run the project (nanohive-1.org/atHome) and used
GROMACS to generate tooltip conformations for quantum chemical minimization
- The goal of the project was to find failure modes for 25 published C2 dimer tooltips.
- The approach was to perform a molecular dynamics simulation of each molecule at a very high temperature so that it deformed and undulated significantly, then to perform quantum chemical geometry optimizations on each deformed variant produced in the simulation. This approach mechanized the creation of initial, unstable structure variants that could then minimize to alternative structures.
- Designed and implemented an HDF5-based simulation results library and int- egrated it within GROMACS as a new format for writing simulation results data such as trajectories and energies.
- Prototyped the integration of GROMACS with NanoEngineer-1 (a molecular chem- istry CAD tool) for atomistic and reduced model molecular dynamics and energy minimization of DNA.
- Lead the design and development of NanoVision-1, a cross-platform, Qt-based application that displays chemical structures and simulations especially those produced by NanoEngineer-1 and GROMACS.
- Designed and implemented a modular, cross-platform, simulation framework for molecular modeling. The architecture supports plugins for simulator control, data import/export/storage, multiscale time/space traversal, distributed computing, physical interactions, and simulation results.
- Created plugins for
- Simulator control via Java, TCP sockets, and Python.
- In-lab distributed computing (DC) via sockets and @Home-style DC via the Berkeley Open Infrastructure for Network Computing (BOINC).
- Integration of Reactive Empirical Bond Order (REBO) molecular dynamics, and ab initio methods such as Hartree-Fock, Kohn-Sham DFT, and Møller-Plesset perturbation theory.
- Simulation results via netCDF data files and POV-Ray scene descriptions.
- Created NanoHive@Home, a distributed computing system used for large-scale nanotech systems simulation and analysis that draws its computing power from otherwise idle computers sitting in people's homes.

- Designed and led the implementation of a fully distributed computing environ-
ment (DCE) for use in pre-processing the national telephone directory for use
in a speech-enabled directory assistance application.
- DCE features include sophisticated job specification, fail over and retry mechanisms, graphical control and monitoring interface with login-controlled access levels, SNMP messaging, and an extensible framework.

- Managed the QA department and developed tools and techniques for testing the performance of a speech-enabled national directory assistance application.
- Co-Inventor of patent #6671670 - System and method for pre-processing infor- mation used by an automated attendant.
- Met with customers to explain ideas about how web, and related technology could help them achieve their marketing objectives, then later to discuss design and implementation details and planning.
- Collaborated internally with sales associates, media production personnel, and graphic artists.
- Managed a team of (3-5) programmers to deliver web promotions and sites ranging from referral programs to sophisticated on-line shops complete with secure product purchase, product search and reviews, affiliate programs, membership reward point system, gift registry, and configurable communities.
- Maintained a multi-platform network (Solaris, Linux, NT, Mac OS X) running Apache web servers, Oracle and MySQL databases.
- Spun-out Telelogue, a speech applications startup: prototype/demo development, product definition, and business plan.
