Big Information Analytics, Opera Design

Our Tensor platform transforms predictive analytics into deployable products, making it easier for analysts to create and maintain models. Despite significant investments in data warehouses, enterprises often struggle to realize a return due to the labor-intensive nature of traditional predictive analytics. The Tensor project at Opera Solutions leverages agile programming methodologies, significantly reducing modeling time. By using automated builds in Jenkins, we enable one-click model training and versioning through Maven, which packages all necessary components for model deployment. This streamlined approach allows for automatic publication of key variables and statistics for performance evaluation. We also incorporated advanced algorithms like Generalized Linear Models (GLM) and multi-threaded Restricted Boltzmann Machines (RBM) to support our analyst community.

Web 2.0 Mash Up, Found Value

My background as a development executive and architect led the founders of FoundValue to seek my help after securing funding from Sequoia Venture Capital and launching their beta product. FoundValue employs Web 2.0 techniques to integrate services like eBay and PayPal, enabling specialists to sell items on eBay for others while managing listings, payments, and shipping details.

The platform, however, faced significant challenges due to buggy APIs, unreliable updates, and poor testing, compounded by the choice of ASP.Net and C#, which caused sporadic bugs and high implementation costs. I established a prioritization process for addressing bugs and feature requests based on value and risk, mentored the development team, and oversaw recruitment in a competitive Bay Area market. My contributions ultimately improved the team’s productivity and success.

Web Based Clubs, Excite.com

Excite Clubs was the fifth most-traveled site on the web, reaching over 20 million page views per day and accumulating more than a terabyte of data. This popularity posed challenges with rapidly increasing traffic that doubled every two weeks and a competitive market with numerous imitators demanding extensive features.

As the principal architect, I initially improved performance by normalizing the data model and then applied object-oriented design techniques and agile methodologies. This approach enabled us to deploy high-quality, compelling features, including a unique activity tracker that helped users identify unseen club content.

Excite Clubs was a pivotal point in my career, demonstrating that effective agile processes, stringent metrics, and solid architecture can ensure successful product delivery in a volatile environment, ultimately enhancing both the platform’s features and popularity.

Music Studio, Midisoft Corps

Midisoft Studio is a successful MIDI sequencer that sold over two million copies, receiving accolades such as runner-up for technical excellence from PC Magazine in 1992 and praise from Musician magazine for its notation interface. It was featured by Bill Gates during his keynote at the kickoff of Windows 3.1 at Comdex 1991.

When I joined Midisoft, the company had excelled as a DOS application but faced challenges transitioning to the Windows graphics-based market. This transition required innovative solutions to address the limitations of the emerging Windows operating system and tight marketing deadlines.

In this context, we enhanced quality, developed unique features, and created novel algorithms, resulting in an award-winning product that became the gold standard for Windows multimedia applications

Peer to Peer Clubs, X-Spaces Inc

RedRover is a peer-to-peer community application that reduces infrastructure costs typical of similar platforms. Our team developed a groundbreaking technology that demonstrates the power of agile methodologies, particularly through Extreme Programming. This approach fostered an environment where engineers could contribute in their spare time, resulting in high-quality code at a rapid pace.

RedRover includes features like chat, photo sharing, and timelines, utilizing novel load balancing algorithms based on machine learning to address challenges of other peer-to-peer platforms. The project showcased how Extreme Programming metrics could effectively manage advanced algorithms and emerging technologies, leading to a scalable, maintainable architecture free of known defects.

Bedside Client, Bridge Medical

MedAdmin minimizes medication delivery errors in hospitals by connecting clinicians, patients, and medications. Upon joining Bridge, I faced a lack of software development and processes, which had stalled new releases for over two years.

To resolve this, I established an agile methodology based on extreme programming, improved documentation for 510K certification, and created training materials for the team. I also implemented metrics to track progress. This led to the timely release of four new software versions with near-zero defects, enhanced performance, and a 98% reduction in customer support calls, revitalizing the project and boosting the team’s reputation at Cerner.
