> Hands on Software Developer and Architect

Location: Mountain View, California, United States
Profile: https://flows.cv/antoniosi

Graduated from the Computer Science department, University of Southern California. My Ph.D. thesis involves developing a prototype multi-database system to collaborate data among a collection of heterogeneous autonomous databases.

Since graduating, I have been working as an Assistant Professor in Hong Kong Polytechnic University for 3.5 years. I have secured several research fundings from the government and have supervised several research students. My areas of teaching and research are mainly focused on distributed database and data caching mechanism.

My first industrial job is with Sun Microsystems, working on an internal tool to manage a collection of bugs data repository.  After I left Sun Microsystems, I worked with various companies including well-established enterprises and startups, such as Terracotta, NASA Ames, and Oracle.

I am now with Intuit, involved in architecting and developing various big data processing solutions.

### Software Developer V @ Oracle Corporation
Jan 2013 – Jan 2018
Currently, I am working on a cloud-based ETL product, trying to connect data from various data pipelines and performing transformations using spark program. The framework utilizes hadoop as a persistence layer for intermediate data and Alluxio as a distributed caching layer. Hive is used to query external data ingested by the data pipelines.

I also help mentoring junior developers, guiding them through various phases of a project, from start to finish.

. Re-engineer Seda and construct the UML class diagram and 
sequence diagram. 
. Extend Seda to support POST method. 
. Integrate with the Bayesian network inference engine and
  resolve the multi-threaded synchronization problems. 

Involve in designing the Utility Computing system that automates the Data Center resources and operations using BPEL and Web Services.
