Full-Stack JavaScript Developer building scalable web applications with clean architecture and real-world impact.

Focused on building scalable systems and continuously evolving as a modern engineer.

🖥️ Full-Stack JavaScript Developer
⚛️ Strong in React & modern frontend ecosystems
🟢 Backend experience with Node.js & API design
🧠 Focused on clean code, architecture & performance
🚀 Building real-world tools, not just demo apps

I care about writing maintainable code, designing scalable structures and continuously improving both technical and architectural thinking.

React TS Kit is a TypeScript-first React utility & UI toolkit focused on clean abstractions and scalable architecture.

This is my long-term experimental playground where I:

• design reusable patterns
• test architectural decisions
• improve developer experience
• build production-ready utilities

The project is in early stage and evolving continuously.

I’m currently exploring how AI can meaningfully improve real development workflows — not just speed, but code quality and architecture thinking.

Experimenting with:

• GitHub Copilot
• Cursor AI
• AI-assisted refactoring
• Prompt-driven development workflows

My goal is to understand where AI truly adds value in professional software engineering — and where it doesn’t.
