🙋 About Me

🌟 Who I am
Full-Stack Web & Mobile Developer turned AI enthusiast. I build responsive, real-time, user-focused applications with clean, scalable code — using MERN stack for web platforms and native Android for mobile apps that solve real-world problems. Passionate about turning human intent into precise AI behavior through effective prompt engineering and LLM orchestration.

📚 Currently Learning / Diving Deep

  • AI • ML • DL fundamentals and advanced concepts
  • Large Language Models (LLMs) and prompt engineering
  • AI Orchestration with LLMs — coordinating agents, tools, chains, multi-model workflows, RAG, and intelligent decision-making systems (exploring frameworks like LangChain, CrewAI, etc.)
  • Cloud deployment, scaling & DevOps (AWS, Vercel, Docker, etc.)
  • Integrating AI into full-stack and mobile applications for smarter features

🚀 What Drives Me

  • Building meaningful, high-impact products that blend great UX with intelligent backend logic
  • Pushing boundaries by combining web/mobile development with cutting-edge AI
  • Unleash the AI's full potential through the "art of Prompt Engineering".
  • Open-source contributions, knowledge sharing, and meaningful collaborations
  • Writing maintainable, performant, and future-proof code

👯 Open to Collaborating on

  • 🛒 E-commerce & marketplace platforms with smart recommendations
  • 🤖 AI-powered applications, intelligent agents, chatbots & LLM orchestration projects
  • ⚡ Real-time full-stack systems (WebSockets, live features)
  • 📱 Mobile-Web hybrid apps with AI enhancements
  • Any project where AI meets practical user-facing products

🎯 Vision
Evolving into a Full-Stack + AI Engineer to create intelligent, autonomous, and truly transformative applications that make people's lives easier and better.
