Yalla on a phone: live campus map, group chat and a club dashboard

A mobile-first social app for university students: a live campus map with friends, hangouts with group chat, and club communities. Privacy is enforced by the database itself: ghost mode by default, location visible only to mutual friends and expiring automatically, and silent account deletion. Installable on iPhone and Android as a web app, deployed on Cloudflare Pages with a Supabase backend, and covered by 303 automated tests that include attempts to break the security rules.

PythonFastAPILlamaIndexQdrantOpenAIInngestDocker

A Retrieval-Augmented Generation application for document-based question answering — PDF ingestion, chunking, embedding generation, vector retrieval in Qdrant, and LLM-based response generation, with backend workflows built on FastAPI and Inngest.

Streamlit page after uploading English.pdf: a green banner says ingestion was triggered, and a question is being answered — 1 · Upload a PDF: ingestion starts

The Answer section: a summary of the uploaded PDF with the source files listed — 2 · Ask a question: answer with its sources

Inngest dev server showing completed RAG Query and RAG Ingest PDF runs, with a trace of the search and answer-question steps and the JSON output — 3 · Inngest dev server: each run is traced (search, then answer-question) and returns the answer and its sources

PythonpsutilPostgreSQLSQLAlchemyFastAPIStreamlit

Monitoring system collecting CPU, memory, disk, and network metrics with psutil, persisted in PostgreSQL via SQLAlchemy, and exposed through a FastAPI REST API with a Streamlit dashboard for historical trends.

Streamlit dashboard: CPU and memory usage over time in one chart, with a tooltip on a data point — Dashboard: CPU and memory history in one chart

Linux Monitor dashboard: CPU usage chart over time — CPU history. Straight segments mark periods when the collector was stopped
