Built a record linkage engine that is maintained in Scala to process very large data (500GB+ compressed) and join to an even larger data warehouse (10TB+ compressed). The data is stored in columnar format – Parquet – to enable data skipping and efficient bloom filtering. Worked with Elasticsearch to load data to be consumed by API and easily searchable Migrated an on-premises Hadoop and HQL implementation to Amazon Web Services (AWS) and updated an HBase-centric implementation to a Data Lake oriented implementation using Elastic Map Reduce (EMR) and S3. Logging and monitoring are implemented using SumoLogic Created data pipelines in Airflow and CI/CD using TeamCity and S3

Worked with a team of developers to maintain our Oracle database and associated .NET services which delivered data to Process Engineers Maintained a local website (Frontend: React, API: C#, Database: Oracle) which presented data to make informed decisions Worked with team to implement sprint-based system including code review

Davis, Ca

Created a video based report card that takes students marks from an excel database using Excel macros and MS Access. Translated into an html video via JavaScript to create a playable mp4.

Work with social media API’s such as Twitter, Instagram, and Vine. Search API’s to find trending stories for use in media. Use results to add additional information from other API’s such as adding Instagram pictures to a story created from twitter hashtags.
