About

I am energized by continuous learning and keen on building strong technical skills by challenging the status quo and going beyond my comfort zone. I am particularly interested in the art of software engineering in a big data environment and delivering business value from large and haphazard data sets. In summary, I have: • 2 years of hands on experience using Akka, Spring Boot and the Hadoop ecosystem (Cloudera) • 2 years of cloud development experience on Force.com and Heroku • 1 year of experience in supporting a production enterprise cluster • Fluency in both written and spoken English, French, and Korean
