Things I've designed, built, or broken and rebuilt. Most have source on GitHub.
A healthcare documentation assistant that turns spoken or written nursing handover notes into validated, structured care records. Faster-Whisper transcription feeds provider-neutral LLM extraction (Groq, OpenAI or Ollama), then Pydantic validation and confidence scoring flag anything a human should review.
Detects inflated expertise claims in candidate profiles by scoring timeline inconsistencies, buzzword patterns and web signals into a feature vector. A PPO-trained policy in a Gymnasium environment then decides PASS, FLAG or ASK_MORE, and every verdict ships with the evidence behind it.
A web-based chatbot using Retrieval Augmented Generation with chat history as context, giving accurate answers to frequently asked customer questions.
Predicts stroke risk from patient health records. Compares Logistic Regression, Random Forest and XGBoost with class-imbalance handling, then tunes the decision threshold for recall — the metric that actually matters when a false negative is a missed stroke. Deployed as a Streamlit app with per-patient insights.
A machine learning web app built with Streamlit that predicts the onset of diabetes from diagnostic measures.
A platform for customers to get electrical equipment repaired, and for technicians to find repair jobs.
A full-stack app showcasing CRUD operations with MongoDB and React — improved backend data handling and database interactions behind a dynamic frontend.
A full-stack ordering app with React on the front and Express behind it — Context API, custom hooks, useReducer and middleware for state and HTTP.
An engaging, interactive platform built with Next.js and React where food enthusiasts share favourite recipes, discover new dishes, and connect with other food lovers.
An interactive web app for looking up place details, with autocomplete that predicts places based on the user's current location input.
A project management application in React that lets users create and manage projects and their tasks efficiently.
A dynamic challenge tracking application covering state management, Context API, animations and routing.
An events app with full event management, efficient routing, intuitive form submissions and data management.
A React quiz app with timed questions, immediate feedback, and a detailed performance summary at the end.
A food ordering front end — pick items, add them to a cart with quantities, and adjust the order before checkout.
A React game where players try to stop a timer as close to a target time as they can.
An investment calculator where changing any input dynamically recomputes the whole results table.
An OTP-based login system in Java and Swing that generates a one-time password by hashing the current timestamp with SHA-256 and delivers it over Gmail SMTP.
