Algorithms · Real-world routing

Bangladesh Route Optimizer

The problem

How can a route visit multiple locations using road distances rather than straight-line estimates?

How it works

The project uses real driving distances from OSRM instead of straight-line distances. Python prepares road data and Folium maps; a separate C++ bitmask dynamic programming solver finds an exact route for the smaller, 15-hub problem.

C++ · Concurrent systems

TurboCache

The problem

How can a key–value server handle several clients while keeping shared data consistent?

How it works

A raw Winsock TCP server accepts text commands including SET, GET, DEL, DBSIZE, and PING. A thread pool reuses workers, while a shared mutex protects the store and permits concurrent readers. The repository includes a Python benchmark tool.

Try the commands

Browser simulation

A small illustration of key–value commands. The C++ server is not running here; entries stay in this page and reset when it reloads.

Choose an example above or type SET key value, GET key, DEL key, DBSIZE or PING.

Ready. Try SET name Seyam.

Applied AI · Local document search

VaultMind

The problem

How can someone ask questions about a PDF and trace the answer back to a source page?

How it works

The Streamlit interface connects PDF extraction, CPU-based embeddings, a ChromaDB vector store, and models served by Ollama. It brings retrieval and answer generation together in a local workflow, with references back to document pages.
