Developed a Retrieval-Augmented Generation (RAG) chatbot with memory capabilities, supporting diverse document types. Integrated the Chroma vector store for efficient embedding storage and retrieval, optimized responses through advanced prompt engineering and LLM experimentation, and structured a modular, scalable, and collaborative codebase.



Developed and deployed an AI-powered WhatsApp chat analysis app with a chatbot that processes CSV chat files, enabling users to uncover insights effortlessly. The app integrates advanced NLP algorithms, including emoji analysis and keyword search, to extract meaningful insights from chat data. It features an interactive interface with dynamic visualizations, customizable charts, word clouds, and other plots, enhancing data exploration and user engagement.


Developed and deployed an AI-powered Sentiment Analysis web app with integrated Generative AI, allowing users to chat and derive insights from student feedback to enhance learning experiences. The app achieved 96% model accuracy, offering a deeper understanding of student emotions and assisting lecturers in refining teaching strategies. It also features EDA and interactive visualizations, improving data exploration and user engagement.


This web-app is a book recommender system that uses a content-based approach, leveraging book features to recommend similar books to users based on features of the books or characteristics of the items and the user's preferences. Aspects such as plot, characters, and themes that truly engages the user are taken into consideration. Subsequently, book recommendations are provided that align with the user's tastes. The book data was scraped from Google Books using API calls and then extensive data preprocessing was performed to implement the recommender algorithm.


Addressing a significant industry challenge, this project effectively predicts customer churn in the telecom sector using machine learning. The top-performing model, an XGBoost classifier, achieved an impressive 92% Recall Score in predicting positive cases of "churn" with other impressive performances in other evaluation metrics used too. Insights from this initiative empower the industry to implement strategic retention measures, mitigating churn and boosting customer satisfaction in a sector grappling with multimillion-dollar losses each month due to customer attrition.


This project allows businesses to customize their offerings, products and services to different customer segments, instead of utilizing a generic approach. Through techniques like unsupervised learning, I gain a better understanding of customers, facilitating adjustments to products based on specific needs, behaviors, and concerns of various customer types. For instance, instead of allocating resources to market a new product to every customer in the company's database, I can analyze which customer segment is most likely to make a purchase and then concentrate marketing efforts on that particular segment.


This project harnesses the power of data and AI to forecast and analyze employee attribution trends. Gradient Boosting Algorithms including XGBoost, CatBoost, LightGBM and an ensemble of these models were used to develop robust predictive models that provide insights into employee retention, identify patterns, and contribute to strategic talent management.


I wrangled, analyzed and visualized the tweet archive of Twitter user @dogrates also known as WeRateDogs. WeRateDogs is a Twitter account that rates people's dogs with a humorous comment about the dog. I wrangled WeRateDogs Twitter data to create interesting and trustworthy analysis and visualizations.
The Twitter archive is great, but it only contains very basic tweet information. I then got additional information by querying Twitter's API to gather more data.


In this project, I analyze the Prosper loan dataset using Python to create insightful visualizations. The process involves thorough exploration, data cleaning, and preparation to extract meaningful insights into borrower behavior and loan performance. The objective is to comprehend patterns and trends in the Prosper loan data, covering loan origination rates, borrower credit scores, and critical metrics. These insights are invaluable for informed lending decisions, risk management strategies, and financial analysis. The project serves as a testament to the effectiveness of data visualization in simplifying complex data for a broader audience's understanding.


This project was part of my Data Analyst Nanodegree Programme at Udacity. The soccer database, sourced from Kaggle, is ideal for data analysis and machine learning, containing comprehensive data on matches, players, and teams across European countries from 2008 to 2016. It involved thorough data analysis using SQL and Python, including data wrangling, querying with SQL, and further analyses using Python. Through this project, I gained valuable insights into soccer data patterns and trends, encompassing player performance, team rankings, and other vital metrics. These insights are instrumental in guiding coaching decisions, player recruitment, and other critical aspects of soccer management.


As a football fan, it was always clear that I would apply data science in some way to the sport. This marks my first venture into web scraping. In this project, I'm scraping data from the La Liga football league website using Python's Beautiful Soup library. The scraped data encompasses player statistics, team rankings, and various other crucial metrics tied to the league. The main aim of this project is to collect data for further analysis and to gain insights into player and team performance throughout the season. It's a great showcase of the potential of web scraping for efficiently gathering large volumes of data, presenting a valuable tool for football enthusiasts and analysts alike.
