🎯 The Challenge Selection Friction & Decision Paralysis: Traditional wine e-commerce filters are overwhelming for non-expert buyers who struggle with complex sommelier terminology. Custom Conversational AI Engine: Training and integrating an LLM capable of accurately understanding domain-specific wine terms, tasting notes, and meal pairings in real-time. Ground-Up Architecture: Building a high-performance web platform and API infrastructure capable of linking conversational chat outputs directly to live inventory, cart systems, and checkout flows without latency. 🛠️ What We Developed 1. 🏗️ Custom Web Platform (Ground-Up Build) Designed and engineered a modern, high-performance web application tailored specifically for wine and gastronomy sales. Built a clean, mobile-first responsive interface with custom product cards, filtering systems, and order management workflows. 2. 🍷 AI Sommelier Engine Implemented a custom LLM-based recommendation pipeline trained on detailed wine metadata (tasting notes, grape varieties, body, acidity, aging, region, and food pairings). Enabled natural-language inputs (e.g., "I'm having grilled salmon tonight and need a crisp white wine under $30"). 3. 💬 Digital Wine Chat Assistant Integrated a real-time interactive chat module with streaming responses (via WebSockets). Embedded interactive product cards directly inside the chat interface, allowing users to add AI-recommended bottles to their cart with one click. 4. ⚡ Seamless E-Commerce & Inventory Integration Connected the AI assistant directly to real-time database stock levels, pricing tiers, and checkout pipelines. 💻 Tech Stack & Architecture LayerTechnologies & ToolsAI & NLP IntegrationOpenAI API, Custom LLM Prompt Engineering, Vector Embeddings, LangChainFrontendReact.js / Next.js, Tailwind CSS, WebSocketsBackend APINode.js, Express.js, REST APIDatabase & CachePostgreSQL (Wine Catalog & Metadata), Redis (Session Caching)Deployment & CloudDocker, Nginx, Linux / AWS 📊 Key Results & Business Impact 100% Custom Delivery: Successfully launched a complete end-to-end platform built from scratch. 40%+ Engagement Rate: Over 40% of unique site visitors actively consult the AI Sommelier during their browsing session. +28% Higher Average Order Value (AOV): AI-generated food pairing and multi-bottle suggestions significantly increased order size. Reduced Cart Abandonment: Instant conversational guidance eliminated choice paralysis, driving higher checkout conversions.

AI Engineer building LLM, RAG & AI automation solutions
Cover image for Collaborative project built at Kaggle
Collaborative project built at Kaggle Week 26 GenAI Hackathon, contributed the core AI engineering layers of a Business Law RAG Assistant that answers legal document queries with source citations and live faithfulness verification. My contributions: built the hybrid FAISS + BM25 retrieval pipeline for accurate document search; designed the multi-agent orchestration system coordinating retrieval, generation, and verification agents; implemented the faithfulness verification layer to evaluate and score LLM output quality; integrated an MCP tool server enabling live web search as a fallback; and built the analytics dashboard tracking query performance and retrieval metrics. Built as part of a 4-person team, my work covered the RAG pipeline, agentic architecture, and evaluation infrastructure.

Cover image for Collaborative project, contributed key production
Collaborative project, contributed key production components of Med-V²QA, a clinical Visual Question Answering system built on the MUMC architecture for radiology image analysis. My contributions: built the Dual-Gate Guardrail System (Gate 1 rejects non-medical intent, Gate 2 uses a local CLIP classifier to reject non-medical images ensuring clinical safety and system focus); developed the Batch Triage module using zero-shot CLIP to automatically sort and prioritise the most abnormal scans from uploads of up to 20 images; integrated Voice I/O using OpenAI Whisper for speech-to-text transcription and gTTS for audio readout of answers; built the PDF report generation module producing structured clinical reports with patient data, notes, and VQA results; and developed the FastAPI backend handling high-performance async request processing across all services. Built as part of a team my work covered the safety layer, multimodal I/O, clinical reporting, and backend API infrastructure.
