Expertise in providing big data solutions when off-the-shelf won't cut it.Invented a scalable ETL framework API service more flexible than AWS Glue (and faster/cheaper than many EMR/Spark solutions) for managing our complex and frequently changing ETL needs in real time. Created web crawling engine capable of crawling hundreds of popular websites to deliver terabytes of data on demand; then, did it again it with better tech for orders-of-magnitude improvements in speed/cost/scalability.Boosted our manual data curation up to "game changer" status with custom algorithms, web UIs, and machine learning techniques.As the creator and owner of multiple stages of our product pipeline, I am also the company's QA engineer for data integrity. I do it all - prototyping, documentation, support, mentoring, analytical reporting, production, data-mining, back-end to front-end.Amazon Web Services: S3, Athena, EC2, Lambda, API Gateway, DynamoDB, Glue, EMR, SQS, SNS, CloudFormation, CloudWatch, Machine LearningAlso: Java, C++, NLP, Perl

Developed big data pipeline with coworker for hundreds of servers around the world. Collected, aggregated, transformed, and published tens of GB per hour with just 10 minute latency. (Hadoop, HDFS, Pig, Java, map-reduce, Flume, Perl, Linux)Developed log collection application to combine logs from multiple sources and formats into one schema and aggregate and publish on Hadoop FS. Enabled dozens of consuming business units to access data from one source reliably. Accomplished ahead of scheduled before old data warehouse decommission. I successfully played the roll of project manager as I managed every aspect of the project from beginning to end, overcoming red tape and blockers along the way. (Hadoop, HDFS, Pig, Java, Perl, Linux)Two-time winner of company-wide contest for creative use of the video player. Won Funniest Hack and Best Video Hack for entries that combined animation, sound, and responsive elements with video playback. (Adobe Action Script)Co-developer in two-man team to reverse engineered and moved complicated undocumented live telephone audio encoding application to a new data center in record timing, having no previous knowledge of the technologies involved. This enabled Yahoo! to continue support of broadcasting live audio events on the internet past the deconstruction date of the old data center. Received recognition from four levels of management. Named in patent application. (Visual Basic, VBScript, Active X DLLs, ASP, telephony, Windows, C++)Invented replacement for cross-data-center communication backbone of world-wide video content ingestion system with new design. Old method of remote script execution was insecure and unreliable. New version passed Yahoo! security requirements and had 0 failures over first 3 months of monitoring. Won award for best support documentation from service engineering team. (IIS, http, encryption, Windows, Visual Basic, VBScript, ASP, Active X DLLs)

Developed new methods of generating reports for high-profile live video events. This gave Yahoo! bragging rights to publicly announce statistics on each event, such as number of viewers, within just hours of the event's conclusion. (Hadoop, HDFS, Pig, Java, Perl, Linux)First to discover and fix bugs in company-wide video reporting application to boost the accuracy of the video counts from 80% to 100%. This prevented the company from being over-charged by some clients, and prevented the company from under-charging other clients. (Perl, Unix)Yahoo!'s miniature golf team captain for the Richardson Coorporate Challenge 3 years in a row to raise money and awareness for the Special Olympics.
