Who I am

About Me

Hey! I'm Aditya Ranjan Jha, a self-taught systems developer from India focused on backend infrastructure, Linux systems, and performance-oriented engineering.

I build modular backend services, real-time communication systems, and experimental systems projects — including RF-based human presence detection and Rust performance exploration. I'm a daily Arch Linux user who enjoys configuring development environments and digging into how things work under the hood.

My interests lie in distributed systems, infrastructure tooling, and high-performance backend engineering. I'm always shipping something new and deepening my understanding of networking and distributed architectures.

Things I've built

Projects

Rust

WiFi RF Human Presence Detection

Experimental RF sensing system that detects human presence via WiFi signal fluctuations — includes a signal processing pipeline and real-time visualization dashboard.

HTML

web_piper_tts

Browser-based text-to-speech using the Piper TTS engine — convert written text to natural-sounding audio right in the browser, no backend needed.

Markdown

doc

Personal documentation repository — notes, references, and write-ups covering systems topics, tooling, and engineering concepts collected over time.

Python · FastAPI

Modular Backend API Platform

Scalable FastAPI services with modular routing and async request handling. Designed for maintainability with reusable components and clear service separation.

Python · WebSockets

Real-Time WebSocket Communication System

Backend messaging system using persistent WebSocket connections — covers connection lifecycle management, event-driven communication, and async networking.

Rust

Rust Performance Exploration — Matrix Computation

Cache-optimised matrix multiplication with threading. Benchmarked against NumPy to study memory locality and parallel execution, exploring Rust's low-level performance techniques.

Python

Custom Language Model Implementation

Simplified pipeline for tokenization, preprocessing, and training workflow. Studied attention mechanisms and architectural tradeoffs to understand internal model mechanics.

JavaScript

learnjs

A hands-on JavaScript learning repo — documenting experiments and progress while mastering the language from scratch.
