ACHIEVEMENTS

Objective: A real estate agency wanted to reduce the negotiation time and improve closure for buyers and sellers of homes by ensuring that both sides were advised well on the potential sale/purchase price of the home. Tech Stack: Python (jupyter notebook)

Solution: Created Random forest regression using Python to arrive at a potential transaction price for all future transactions

Key Achievement: Proposed a reduction in negotiation time from an average of 3 weeks to 8 days & a 25% jump in closure

Objective: Detected fake news by distinguishing fake and actual news. Tech Stack: Python (jupyter notebook)

Solution: Built TfidfVectorizer and initialized a PassiveAggressive Classifier to the model. Key Achievement: Detected fake news with accuracy of 93% Objective: Detected the credit card transaction fraud. Tech Stack: Python (jupyter lab)

Solution: Deployed Deep learning model mode with keras. keras Enhanced 3 hidden layers with Rectified linear unit and SSiiggmmooiidd activation functions

Key Achievement: Achieved a model accuracy of 99% and predicted the classes. Objective: A bank was rolling out a new term deposits product and wanted to predict which of their existing customers to target as part of maximizing ROI

Tech Stack: R

Solution: Deployed Logistic regression to create a propensity model to predict those customers most likely to respond positively to the new product and the campaign

Key Achievement: Achieved a model accuracy of 92% and registered a KS score of 64% Objective: A mid-sized IT company needed to plan its hiring and reduce risk of projects getting delayed due to employees leaving. It also wanted to understand why its attrition rate was high and how it could be reduced Tech Stack: R

Solution: Designed Decision tree model along with a Random forest model to predict attrition and also to better understand the factors related to attrition taking place Key Achievement: Achieved a model accuracy of 90% .Communicated the findings to the client Tech Stack: R

Sentiment Analysis Showed More Positive feedback, feedback which was left by people who bought products and got satisfactory out of them. Less people expressed Disgust Feeling, Feeling However some customers expressed Other sentiments as well. Languages: English, Telugu and Hindi

Secured 1st Prize among 100 entries in Think-Tank, Adsomniac and Business Quiz in vidwan Organized By S.B.I.T college Secured 2nd place among 50 competitors in Short Films Competition in Bomma premier league Organized by BOMMA college
