Expert Level (Production Ready):
  Java:
    - ✅ Data Structures & Algorithms (DSA)
    - ✅ Object-Oriented Programming (OOP)
    - ✅ Design Patterns & SOLID Principles
    - ✅ Java Swing - Strong proficiency
    - ✅ JavaFX - Good command with FXML
  
  C++:
    - ✅ Core language & memory management
    - ✅ Qt Framework for desktop apps
    - ✅ Systems-level programming

Intermediate Level (Active Learning):
  Python:
    - 🔄 Scripting & automation (Bash + Python)
    - 🔄 NumPy fundamentals cleared
    - 🔄 Pandas data manipulation
    - 🔄 Matplotlib visualization
    - 🔄 AI/ML concepts in progress

Supporting Tools:
  - ✅ Git CLI mastery (zero GUI dependency)
  - ✅ Windows CMD power user
  - ✅ Arch Linux terminal expert
  - ✅ Browser keyboard navigation (Vimium-style)
  - ✅ Cross-platform shortcut fluency
  - ✅ Mouse-optional efficiency mindset

# My development environment reflects a simple principle:
# "If your hands leave the keyboard, you're losing time."

$ whoami
→ Keyboard shortcut obsessive who memorized every Windows, Arch, and browser hotkey

$ workflow --describe
→ CLI-first developer: Git commands over GUI, terminal over mouse clicks
→ Neovim devotee: hjkl navigation, zero mouse dependency
→ Automation fanatic: If it's repetitive, it gets scripted

$ efficiency --metrics
→ Windows: Win+[1-9], Alt+Tab muscle memory, PowerShell automation
→ Arch Linux: i3wm/sway bindings, terminal multiplexing, everything scriptable  
→ Browsers: Vimium-style navigation, keyboard-only browsing
→ IDEs: Custom keybindings, modal editing everywhere possible

$ philosophy
→ "Master your tools so they become invisible"
→ "The mouse is for design work, not development"
→ "Every repeated action deserves a keybinding"

Impact: This keyboard-first approach translates to measurably faster coding, navigation, and task completion. Every app I use gets its shortcuts memorized within the first week.
