• 💬 Who am I? I am a FullStack AI Developer with over 5 years of experience building scalable platforms and bringing artificial intelligence systems to production. I specialize in backend architecture, Retrieval-Augmented Generation (RAG), and advanced conversational AI using both text and voice. I thrive in designing complex event-driven systems and creating dynamic React interfaces to connect users with powerful AI tools.

• 🤖 What am I currently working on? I am actively developing complex multi-agent AI systems and orchestrators. My day-to-day stack involves building autonomous agent workflows using LangGraph, NestJS, and TypeScript, integrated directly with cutting-edge LLMs like OpenAI, Llama, DeepSeek, and Qwen.

• 🗣️ Voice & Conversational AI: I build real-time, interactive voice agents by orchestrating tools like Twilio, ElevenLabs, Deepgram, Vapi, and Telnyx, enabling seamless human-like interactions and autonomous task execution (like technical dispatching and automated alerts).

My expertise lies in integrating Large Language Models into production-ready environments. I design autonomous agents and complex decision-making graphs.

• Models: OpenAI, Llama, DeepSeek, Qwen.
• Orchestration & Frameworks: LangGraph, LangChain, LlamaIndex, Haystack, MCP, A2A.
• Techniques: Prompt Engineering, Function Calling, Tool Orchestration, and building robust RAG systems backed by Pinecone and Redis vector searches.

I develop state-of-the-art voice and text conversational systems capable of real-time bidirectional communication via WebSockets.

• Voice & Telecom Stack: Twilio, ElevenLabs, Deepgram, Vapi, Telnyx.
• Social APIs: Official Meta APIs (WhatsApp, Instagram, Facebook).

I build highly scalable, event-driven backends focusing on clean architecture and high performance.

• Core: Node.js, NestJS, Python, Go.
• Architecture: REST APIs, WebSockets, Event-Driven, Kafka.

I bridge the gap between complex AI logic and user experience by building dynamic web applications and interactive AI dashboards.

• Core: React.js, Next.js, TypeScript.
