Hi, I'm Siddhesh Pardeshi 👋

Software Engineer • Graphics Programmer • Systems Enthusiast

I enjoy building things from first principles.

While my day job involves building large-scale web applications using React, Angular and TypeScript, most of my free time goes into exploring how software works beneath the abstraction layers.

That curiosity has led me to build:

🎮 A custom 3D renderer from scratch using WebGL
⚙️ Physics engine components (GJK, EPA, XPBD)
🧠 Neural network experiments in C
🤖 AI-powered applications using LLMs and RAG
🖥️ Operating system, compiler, emulator and systems programming projects

Current Role

Frontend Engineer @ Darwinbox

Building enterprise-scale HR and Payroll software used by organizations across the globe.

Work includes:

React & Angular applications
TypeScript architecture
Design systems & component libraries
Performance optimization
AI-powered workflow automation
Full-stack feature development

Philosophy

The best way to understand a system is to build one.

That's why I enjoy creating things from scratch—even when a library already exists.

Whether it's a renderer, a physics engine, a neural network, or a web application, I like understanding the underlying mechanics rather than treating them as black boxes.
