Currently Exploring

Deliberately moving toward lower-level, systems-oriented AI engineering.

AI From First Principles

  • Neural networks from scratch
  • Backpropagation
  • Optimization algorithms
  • CUDA & high-performance AI

AI Infrastructure

  • Custom ML frameworks
  • Python / Rust / C++ systems
  • Hardware-aware AI
  • Local AI systems

Intelligent Software

  • AI-powered productivity tools
  • Smart scheduling
  • Speech-to-text applications
  • Intelligent information retrieval

Some of these are future projects rather than completed work — including ClassBud, AI-from-scratch implementations, a custom AI framework, and a local AI generator.


Engineering Direction

Web Development
      ↓
Full-Stack Engineering
      ↓
Backend + Databases
      ↓
AI Applications + RAG
      ↓
AI Agents + System Architecture
      ↓
Real-Time + Distributed Systems

Systems-Level AI & Custom Infrastructure

The goal isn't to collect frameworks — it's to understand how complete systems work, from interface to backend, database, AI layer, and infrastructure.
