Software Engineer, Technical Lead, and Open Source contributor currently transitioning into AI Software Engineering.

My background is in frontend architecture, developer tooling, and modern web applications. Over the past years I've built libraries, documentation tools, design systems, and large-scale applications using React, Angular, TypeScript, and Node.js.

Today, my primary focus is understanding how modern AI systems work—from first principles to production-ready architectures—while documenting the entire journey in public through my AI Journey repository.

I'm currently studying and building production-oriented AI systems, including:

• Large Language Models (LLMs)
• Transformers
• Embeddings
• Retrieval-Augmented Generation (RAG)
• AI Agents
• Model Context Protocol (MCP)
• Vector Databases
• AI Infrastructure & Inference
• AI System Architecture

My goal is not only to use AI APIs, but to deeply understand how modern AI systems are designed, implemented, and deployed.

• AI Software Engineering
• Frontend Architecture
• Developer Experience (DX)
• Open Source Libraries
• Technical Documentation
• TypeScript & Python
• React, React Router, Angular & SolidJS
• AI-powered Developer Tools

A public knowledge base documenting my transition from Senior Software Engineer to AI Software Engineer.

The repository contains structured lessons, notes, practical projects, and experiments covering Machine Learning, Deep Learning, Transformers, LLM Engineering, RAG, AI Agents, MCP, and production AI systems.
