Her Safety Guide - AI-Powered Web app for safer nighttime travel and housing
Built with React, AWS Services and Google Maps API. Users can plan well-lit routes for safer nighttime travel, browse rental listings for safe housing, explore a 3D model for home security measures. Features an AI-powered Chatbot built with OpenAI and a LangChain agent. The agent interprets user intent, retrieves suburb-specific crime insights, and generates personalised safety guidance, also helping users navigate key features of the app.
AI News Summarizer - Personal AI assistant for summarizing news across globe
Built with Streamlit, OpenAI API, BeautifulSoup, and LangChain, this app summarizes news sites and uses embeddings and RAG to power a chatbot for follow-up questions. I created this tool out of a personal habit: I read the news every morning, but found it time-consuming to browse multiple websites. Now this app is my daily shortcut.
PixTag - Image storage system with advanced tagging capabilities
Built with AWS services and React, this system automatically tags images using an object detection algorithm. Users can search for images by inputting tags or uploading image to find similar ones.
BreathEasy - Android app for tracking local pollen levels in real time
Developed using Jetpack Compose that helps users track pollen levels in their area. Integrated Google Maps API for location-based services and Pollen API for real-time allergy data.
