Welcome to my portfolio website

I'm a seasoned Data Scientist with over half a decade. Having worked extensively with industry leaders, I've now ventured into freelancing, equipped to transform your AI vision into reality.

My expertise spans the adaptation of transfer learning for large language models (akin to ChatGPT), sophisticated image recognition, and state-of-the-art image generation models. But it's not just about algorithms and computations. At the core of my work is a passion for delving deep into data, extracting patterns often overlooked, and crafting them into actionable and insightful strategies. For more visit my LinkedIn profile.

Personalized ChatBot

This article details the creation of a personalized AI chatbot that humorously claims "The Hitchhiker’s Guide to the Galaxy" as the best book ever. The article provides a comprehensive guide, including code snippets, demonstrating how to set up and deploy this AI chatbot, emphasizing the powerful capabilities of LlamaIndex and Streamlit in creating engaging, document-specific chat interfaces. The entire code for this project is available on GitHub, and readers are invited to try out the chatbot through a provided link.

Used Car Price Prediction

This project aims to predict the price of used cars listed on a Hungarian website www.hasznaltauto.hu. The prediction model is built using various machine learning techniques including CatBoostRegressor for handling categorical features, and feature engineering for improving model performance.
