Key Result Areas:
● Planned and engineered RESTful web services to manipulate dynamic data sets using python.
● Researched new technologies, software packages and hardware products for use in projects.
● Web crawler for multiple e-commerce websites using python.
● Data analysis , organisation and extract meaningful information of crawled data using beautiful
soup,regular expression and natural language processing.
● building supervised machine learning models for sentiment analysis using keras,Natural language
processing(NLP), pandas, matplotlib, deep learning(Convolutional neural network and LSTM ). ●
Create an auto correct sentence model using fastText.
● Resolve search classification problems using spaCy and Multinomial Naive bayes.
● Build supervised machine learning model for matching products listed on multiple e-commerce websites
using word2vec,keras library,pandas,image processing, scikit-learn,deep learning (LSTM).
● Created intelligent search engine api using python,PostgreSQL full text search and regular
expression(regex).
