I have worked extensively with MySQL database design and query optimization. I also have experience working with PostgreSQL and some experience with Oracle RDBMS.

I developed my interest in regular expressions (regex) when I used Perl for mining biological text data. After that I have enjoyed using regex in Python, Java and even on the Unix command line with grep.

I have extensive scripting experience with Python. I also use Python's data science libraries numpy, pandas, matplotlib and scikit-learn for data science and machine learning.

Used Redis for server-side caching and helped improve app response times for a relational database backed web application.

Architected Solr cores to help with full text search queries. Also moved data from relational database into Solr for faster query performance.

I have used R for quick data analyses, graphics with ggplot2 and machine learning with caret.

Architected a production application with MongoDB and helped move data from MySQL to MongoDB. Have worked with map-reduce and aggregation frameworks for doing analytics.
