SUMMARY #

As a senior software engineer, I possess extensive expertise in Java programming, with a deep understanding of static analysis, code coverage, and various Java tools. With over 30 years of programming experience in diverse environments, I bring a wealth of knowledge to any development project. Additionally, I have 8 years of experience installing, configuring, testing, and developing Hadoop ecosystem components. My skill set also includes 7 years of quality engineering experience and 2 years of performance engineering experience.

TECHNICAL SKILLS: #

Languages: Java, BPEL, C/C++, Pascal/Delphi, PHP, JavaScript

Big Data Ecosystems: Hadoop, HBase, Zookeeper, Hive, Shark, Spark, Sqoop

Tools & IDEs: Idea, Eclipse, FindBugs, YourKit, Git/CVS/SVN, Bugzilla, Jira

PROFESSIONAL EXPERIENCE #

Unison/WANdisco #

2014-2023

Architect:

Designed and developed HiveMigrator (a critical component of the LiveData Migrator). HiveMigrator facilitates metadata replication between Hive and various platforms such as AWS Glue, Azure SQL, Databricks & Snowflake, enabling seamless data transfer and integration across heterogeneous systems.

Senior software engineer:

Developed the LiveHive plugin that enables WANdisco Fusion to replicate Hive’s metastore, keeping Hive’s metadata (and data) distributed between data centers.
Created a customized distribution that includes tools from the Hadoop ecosystem: Hadoop/Hive/Shark/Spark/ZooKeeper. As a key member of the team, I played a critical role in ~5 major releases. This distribution was used by Nokia as a platform to create their own software for cellular operators and were successfully installed on multiple sites.

In addition, while working on these projects, I’ve identified and resolved numerous bugs in open-source products. Specifically, I’ve fixed around 20 bugs in Hive, three bugs in Hadoop, and approximately 10 bugs in Shark and Spark. I’ve submitted all these fixes to the open-source community and have included them in the code base, demonstrating my commitment to improving the quality of open-source software.
