Pomona College, Claremont, CA

 

EXPERIENCE SUMMARY

John is the Chief Architect at the leading Cloud Software Provider in the Environmental Comppliance Management space. He has successfully lead the architectural design, implementation, deployment and continuing maintenance of the first Cloud solution in the Environmental/Sustainability space. This application has enjoyed great success, including:

- Multiple Fortune 500 customers, including the majority of Utilities in the U.S., major Chemical manufacturers, as well as Oil/Gas producers.

- Handling billions of distinct measurements monthly from customer SCADA systems and other data sources.

- Tracking millions of safety incidents.

- Calculating and reporting GHG emissions.

- Flexibly handling local, state, and federal environmental regulations.

 

John has also lead the design of a new Environmental Finance application, which highlights the potential and real value exposure in a business based on its operations and products (including suppliers), and their effect on the environment. This application has to calculate 4000+ environmental pressures across 5000+ economic sectors and products, and their supply chain, at multiple levels, in real time for customer analysis.

 

PROFESSIONAL EXPERIENCE

John has over 10 years' professional experience in design and development of scalable Cloud (SaaS) software.

 

Software Design

- Designed and implemented a custom security subsystem with inheritable access control lists, rights, users and groups, and policies.

- Designed a flexible "Open-Schema"� solution, allowing customers to model their own data structures, forms, and fields in the Environmental Cloud solution.

- Designed a flexible Dashboard solution, allowing top-down publishing as well as peer-to-peer sharing, of Environmental metrics, tasks, etc.

- Designed a flexible Workflow solution, allowing customers to model their own business processes in the Environmental Cloud solution.

- Designed and implement a customer server-side calculation subsystem, allowing clients to model their own environmental calculations utilizing billions of SCADA and other industrial process measurements.

- Designed a unique customization capability of the solution's User Interface using packaged, embedded "apps" based on HTML5 and JavaSript with REST APIs.

 

Software Architecture and Development

Python/Cherrypy/Numpy/Scipy/Redis

- Designed and implemented an economic/environmental sustainability calculation engine, using Linear Algebra and GPU computations, a DSL for natural language querying, sparse matrices, parallel queue based cluster computations, hosted on Amazon Web Services.

.NET/SQL

- Designed and implemented an in-memory calculation engine and formula script parser that is now used to run custom calculations across billions of SCADA and other industrial measurements.

- Designed a scalable asynchronous message execution subsystem utilizing multiple publishers and subscribers.

- Designed a scalable database back-end architecture allowing for horizontal scale out of database resources.

- Implemented custom lock engine for cross database and cross-application synchronization.

- Designed and implemented an in-memory distributed and transactional object cache.

- Designed and implemented a certificate based mutual authentication system for cross-company trust relationships.

- Designed and implemented a message-based, queued and extensible platform for cross-application and cross-company integration projects.

 

Performance Management

- Systematically investigated, monitored, analyzed, and resolved performance bottlenecks with the data tier as customer use exploded beyond expectations.

 

Technical Project Management

- Lead Cloud integration efforts for major customers such as PG&E, Chevron, DuPont, Sempra, Syngenta. Result: increased automation and pro-active compliance management capabilities for the customers.

- Lead a software project that successfully rewrote PG&E's waste management tool in .NET. Result: Increased productivity and performance, as well as PG&E's commitment to the platform as its standard for compliance management.

- Lead a project that successfully rewrote Syngenta's SERAM data collection tool in .NET. Result: Enabled international access to real-time compliance data for Syngenta's many facilities, and Syngenta's commitment to the platform as its compliance platform of choice.

- Lead all major release of the flagship Environmental Cloud application since 2003. Result: Major increase in product's feature set, as well as major increase in product's scalability and performance relating to data calculations.

- Lead the project to create the first IHLCA driven Environmental Finance Cloud application.
