RAAS - restaurant as a service.I am currently building out a distributed restaurant software service. The components (Catalog, Order, Order Fulfillment, Reporting etc) are REST microservices which communicate via the AtomPub XML protocol. All services are written in Clojure and deployed on the JVM. Technologies employed include Leiningen, Compojure, MySql, AWS, Puppet and Tomcat

I am the lead developer on Kaplan Professional Education's unified contentmanagement system (UCMS) and responsible for the design and implementation ofnew features, full stack code maintenance, product deployment and issueidentification/resolution. The back end is a REST service written in Pythonand deployed on the Google App Engine framework. The front end is a web clientwritten in Javascript.

Video Chat: responsible for the design/build of a distributed multi-channel video/chat system. The application and notification servers are built on NodeJs. RabbitMQ backs the system distribution, Redis for cache and a Wowza cluster streams the live video. The frontend is a flexible javascript client where all modules run securely in an allocated sandbox.Big Data: deployed and maintain a small Hadoop cluster over which we track usage patterns and associations from the raw access logs.

With a focus on the recreational rental property market, the project is a distributed multi-part system that fetches/processes/aggregates and logs accommodation data (calendar, description, rates) from disparate rent-by-owner sites across the web. The data in turn backs a property search engine and supports the analysis of various occupancy metrics.Technologies:An Apache Storm topology, connected to a Kestrel queue, is used to fetch, extract and log the raw property data from web… Show more With a focus on the recreational rental property market, the project is a distributed multi-part system that fetches/processes/aggregates and logs accommodation data (calendar, description, rates) from disparate rent-by-owner sites across the web.

The topology is defined, written and tested in Clojure. The logs are serialized in Avro. Once logged, various Hadoop jobs are run to consolidate the data into forms suitable for search and analysis. At the present time, the outputs are simply exported via Sqoop into a database. The Hadoop entities are written, defined and tested in Java. Show less

Worked as a front-end engineer on Cisco's newly released Quad platform. As a team we designed, implemented and optimized of many of the platforms social tools (activity feeds, notification services, contact/roster management) and framework features. Also, enjoyed being part of a 3 person workplace initiative to re-implement the activity service as a Mongodb-backed feed.

Designed, built and implemented web-based tools and applications for various groups across Cisco.
