I'm a Full-Stack Developer and System Architect with a strong foundation in algorithmic problem-solving and a passion for building production-grade applications. My expertise spans from low-level performance optimization to high-level system design and AI integration.
- 🎯 Currently: Building scalable full-stack applications with Next.js 16, TypeScript, and AWS
- 🤖 AI Focus: Integrating LLMs, building RAG systems, and creating intelligent backend services with FastAPI & Node.js
- 🏗️ Architecture: Microservices, Event-Driven Systems, Clean Architecture, and Cloud-Native Development
- 📚 Always Learning: Distributed Systems, Advanced Database Optimization, and Kubernetes
