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

Areas of interest:

• Dynamic Programming
• Graph Algorithms
• Trees
• System Design
• Computational Geometry

TypeScript • JavaScript • Python • C++ • GLSL • SQL

React • Angular • StencilJS • HTML • CSS

Node.js • FastAPI • Express

PostgreSQL • MongoDB • Redis • Elasticsearch

Docker • AWS • RabbitMQ • Microservices

WebGL • Vulkan (Learning) • QEMU • Linux

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.
