A distributed real-time data processing system that ingests taxi location streams, processes events with low latency, and pushes live results to a dashboard.

Focus

Real-time ingestion and aggregation of high-volume location data with low latency, designed for monitoring moving systems.

Architecture

Events are ingested via Kafka, processed in an Apache Storm topology, and key state is stored in Redis for fast access.

Delivery

Aggregated results are broadcast to a live dashboard using WebSockets for immediate visual feedback.

Tech

Apache Kafka, Apache Storm, Redis, Docker, WebSockets.

A small x86_64 operating system written in Rust that boots under QEMU and implements core OS concepts such as paging, interrupts, a RAM-based filesystem, and a basic interactive shell.

Focus

Build fundamental OS building blocks from scratch: boot setup, memory management, interrupt handling, and command execution.

Architecture

Boots inside QEMU, initializes paging and interrupt tables, uses a TAR-backed RAM disk at root, and provides a simple interactive shell with tab completion.

Runtime

Experimental support for executing WASM applications that render to the framebuffer and return control back to the OS.

Tech

Rust, x86_64, QEMU, paging, interrupts, WASM, framebuffer.

An audio fingerprinting and retrieval system inspired by the classic Shazam approach, designed to match short or noisy audio clips to a reference database.

Focus

Fast, robust retrieval using spectral fingerprint extraction and hash-based matching.

Approach

Converts audio to time-frequency features that are resilient to distortion or noise.
