The Fundamentals: Hypertext Transfer Protocol

Building an HTTP server from scratch is one of those enlightening “wizard” moments in a developer’s journey. It demystifies the magic behind fetch('google.com') and turns the abstract concept of “The Web” into concrete bytes and sockets.

This project, HTTP from TCP, is a Python implementation of a concurrent HTTP/1.1 server. It implements the core of the HTTP/1.1 protocol (RFC 9112) directly on top of TCP, handling everything from parsing raw bytes to managing concurrent connections and chunked transfer encoding.

For years, the division between web development and data science has been clear: JavaScript rules the browser, while Python dominates the backend. If you wanted to run a Pandas analysis or generate a Matplotlib chart, you had to send data to a server, process it, and send the results back.

But with the rise of WebAssembly (WASM), that boundary is blurring.

In this project, I built SveltePy Studio, a fully client-side application that brings the power of Python’s data science stack directly into the browser. By combining SvelteKit for a reactive UI with Pyodide—a port of CPython to WebAssembly—users can upload CSV datasets and generate complex visualizations without a single byte of user data leaving their device.
