The Pipeline system was created to be highly fault-tolerance, resilience and scalable, ultimately operating on a 18-node Hadoop Cluster to process customer and service data for the whole of Toyota USA. Individual components within the pipeline were composed together and wrapped in a way that allowed active feedback, and reprocessing when data or code issues where identified. I was responsible for mentoring and assisting other members of the team with learning the Scala language, creating and running training sessions for the team, performing code reviews, and giving architectural and linguistic guidance. We created a two phase approach for linguistic analysis of data, leveraging both NLP and ML as well as hand-crafted ontologies to yield highly accurate classification and categorization of text data that resided in our system.

Created software architecture including security interaction diagrams leading project architecture and development from inception to production. The Play Framework application was scale tested using Gatling, and the entire codebase was written in Scala. Test Driven development was highly encouraged, and the high test coverage on the system allowed us to launch the system with just a single bug manifesting in the first few months of production usage! A dedicated Asynchronous logging API was developed using Akka to facilitate out of band logging and log aggregate, with the final destination targeted to be a Cassandra data store. The middle-tier application was a RESTful API web-service sitting between a mobile application and third party vendor system giving us the ability not just to proxy API request, but to log, actively cache, and analyze usage patterns to speed up response times and improve user experience.

This project leverages the Play Framework and Akka for parallelization along with a Solr search engine that helps conglomerate and rank search results in a meaningful way for the front end. The second piece is a banking gateway that provided both payment services and issuing services to our web and mobile clients along with a payment gateway UI. This piece also leverages the Play framework to give a clean and elegant architecture for testable and reliable RESTful web services for banking operations. My team and I work to maintain a level of excellence and testability that exceeds expectations and delivers a highly reliable and stable platform. My team takes quasi-TDD model to develop as quickly and with as few defects as possible leveraging BDD style Spec tests in the play framework and a large suite of functional and integration tests to avoid regressions. My role within this project is the senior engineer and architect, I design and document the architecture of the system from the Database schema to the software design creating decision trees and RESTful service design that the team can build from. I also do a significant portion of implementation, but mentor other engineers to familiarize them with the API services, and engage them in learning the Play framework and Scala language.
