AI Solutions & Practical Implementations :
Architected and delivered production-ready AI systems with a strong emphasis on Autonomous AI Agents, Conversational AI, and Intelligent Automation.

• My Digital Twin Chat Bot:Try it at :https://my-twin-bot.vercel.app.

• Intelligent Chat Portlet for Liferay (MCP‑Based) – Designed and built an intelligent chat portlet for Liferay that uses the Model Context Protocol (MCP) to expose Liferay’s headless APIs. Users can create, list and update portal content via natural language (or voice) commands. The portlet integrates semantic search, vector embeddings and a local LLM (Ollama) to understand intent and fetch precise results. Permission checks respect Liferay’s existing roles, and the solution reduced content operation time by ~70 % and support tickets by 50 %
• Voice‑Enabled Digital Twin –An enterprise-grade AI-powered digital twin system built with LLM and OpenAI. This intelligent agent maintains context, understands intent, and automatically qualifies leads through natural conversations. Implemented a browser‑based voice interface for the digital‑twin assistant. Leveraged the Web Speech API to provide full speech‑to‑text and text‑to‑speech functionality in the client, with no server‑side audio processing. Added a settings panel that lets users choose input mode (text/voice/both), output mode and voice gender. The voice features gracefully degrade to text‑only when unsupported.
• Conversational AI & Voice‑bot Expertise – Designed and deployed conversational AI systems and voice bots, drawing on ElevenLabs‑style text‑to‑speech and speech‑to‑text technologies. Experience building hybrid voice/keyboard interfaces that balance privacy and performance and reduce support requests. Applied best practices in latency, privacy and scalable architecture for live voice‑AI platforms.
• Completion of Advanced AI Curriculum – Completed the entire AI Builder with n8n, AI Engineer Core, Agentic, and MLOps tracks offered by Edward Donner. Developed voice agents with n8n and ElevenLabs, learned the Model Context Protocol (MCP), and built multi‑agent systems using CrewAI, LangGraph, OpenAI Agents SDK and AutoGen. Designed Retrieval‑Augmented Generation (RAG) pipelines, fine‑tuned LLMs, and deployed full‑stack AI applications to Vercel/AWS/GCP using Docker, Terraform and GitHub Actions. Built SaaS features such as user management and subscription billing with Stripe and Supabase.
• AI‑Assisted Development – Regularly use AI‑assisted development tools (GitHub Copilot, Claude, Cursor and the n8n AI Assistant) to accelerate coding, improve code quality and maintain efficient workflows.
• Enterprise‑Scale AI Architecture & Agent Orchestration – Architected enterprise AI solutions using argentic design patterns and the MCP. Designed secure, scalable microservice architectures with well‑defined APIs and implemented CI/CD pipelines (GitHub Actions, Terraform) across AWS/GCP. Collaborated with cross‑functional teams and enterprise‑architecture boards to align AI solutions with business requirements, and clearly communicated and defended design decisions. Familiar with authentication/authorization best practices, API/microservice design and modern DevOps practices.
• YouTube Research & LLM Integration – Built a backend service that integrates the YouTube Data API for channel discovery and scoring. Added automatic deduplication, incremental search, and dual‑mode scoring (keyword‑ and LLM‑based). Developed a research dashboard in React/Next.js with configurable queries, AI‑scoring toggle and real‑time run status.
• Engineered Retrieval-Augmented Generation (RAG) systems combining LLMs and vector databases to deliver accurate, context-aware responses across enterprise knowledge bases.
• Implemented no-code/low-code AI automation using n8n, orchestrating LLMs, agents, APIs, and workflows to reduce manual effort and improve operational efficiency.
