Building/Maintaining AWS Data Infra to Manage Injestion and Migration of Data - Lambda, S3, EMR, Spark, Redshift, DynamoDB, Glue, Kinesis, CloudWatch, DMS, DBT, ETL/ELT processes, Athena, Sage, QuickSight, Tableau, Jasper Reports.Extensively used SQL, Numpy, Pandas, Scikit-learn, Spark, Hive etc for Data Analysis and Model Building. Managed and Maintained DMS Data migrations using AWS DMS, Glue, DBT, Data Pipeline, Redshift, DynamoDB etc.Used Python Data Analytics, Sciences and Engineering to build applications to mine and analyze online data with relations to cyber threats both in dark and surface web. Data from dropbox, medhelp, hackforum as well as over 30 other related online forums have been mined and analyzed. Latest project focused specifically on the investigating the outbreak of ransomware both in dark web and surface web forums and finding creative and innovative methods to curb its spread. All projects use NLP, ETL and EDA techniques. Algorithms include LDA, RNN such as LSTM and CNN. General pipelines deal with stemming, stop-word removal, N-gram generation, topic modeling, building training, querying and optimizing models. Java and Python - Developing Automated and Independent Scripts to Crawl the Internet and obtain Cyber Security Indicator informationPython - Data Science Analytics using spaCy, ScikitLearn, pandas, NLTK, gensim, Tensorflow technologiesAlgorithms - RNN, CNN and general Neural network algorithmsLanguages: Java, Python, SQL C/C++, C# ...Conducted Cyber Security analysis on dropbox. Discovered a vulnerability that allowed Dropbox accounts to be crawled with some private information revealed. Wrote a script in Perl that allowed over 50,000 accounts to be crawled during a period of a week. 5,000 of these accounts were open and vulnerable to possible attackers. This information was reported to Dropbox and the vulnerability was fixed. DISCLAIMER: No data from this project was stored because of the related security issues.

General pipelines deal with stemming, stop-word removal, N-gram generation, topic modeling, building training, querying and optimizing models. =>Hacker Forums Project Developed crawlers to access and craw data from the darkweb. Data included the Author's Name, Profile page link, tenure, stars, awards, friends and connections, posts and interactions on the forum. Crawling techniques were a bit more complicated here due to the covert nature of these underground forums. This data has been analyzed using python NLP packages such as gensim, spaCy, ScikitLearn, NLTK, and fast.ai. Next phase involves using Recursive Neural Networks in Tensorflow to train models using whole sentence corpus. Actionable Cyber Intelligence has already been obtained such as some of the main hacking entities in N. Korea and Canada. => StackExchange Family of Forums ProjectOver 100 GB of text data from StackExchange family of forums. Using the above mentioned NLP techniques to analyze them as well as time series to understand cyber events lifecycles and progressions. Also building pipelines to automate the analysis to permit raw data to be fed in on one end and models output on the other.
