Currently working on Cleanytics, an AI-powered data cleaning and analytics platform.
The project focuses on making messy datasets easier to clean, understand, process and analyze through an intuitive interface.
Focus: AI โข Data Cleaning โข Data Analytics โข React โข AI Application Development
A lightweight web application that converts complex JSON data into human-readable explanations.
The application supports JSON parsing, validation, file uploads, drag-and-drop input, automatic structure analysis, statistics and detailed hierarchical breakdowns.
It also demonstrates how structured data can be transformed into a format that is easier for humans to understand.
Tech: JavaScript โข HTML โข CSS โข JSON Parsing โข DOM Manipulation
A Python-based AI voice assistant powered by an LLM.
The project combines speech recognition, LLM-based responses, function calling and external APIs to create a conversational voice interface.
It can interact with services such as weather, news, Wikipedia and YouTube.
