I’m an AI / Generative AI Engineer with 6+ years of experience building intelligent systems that automate workflows, retrieve knowledge, and integrate AI into enterprise platforms. I specialise in designing and deploying AI agents, RAG-based knowledge assistants, and automation solutions that work within existing business environments such as Microsoft 365, SharePoint, CRM systems, and internal APIs. My focus is helping organizations move from AI experimentation to real production systems that improve decision-making, automate manual processes, and unlock insights from their data.

Most businesses don't have an automation problem — they have an intelligence problem. The workflows exist, but they're slow, manual, and dependent on people repeating the same decisions every day. I build AI agents and automation systems that fix that. I design and deploy end-to-end AI solutions — from RAG-powered knowledge agents to multi-step workflow automation — that help companies reclaim hours, reduce operational costs, and scale without adding headcount. Whether you're a startup moving fast or an enterprise managing complexity, I bring the technical depth and business clarity to get it done right. What I Build For You 🤖 RAG AI Agents — Intelligent copilots that answer questions, retrieve documents, and take action using your own data. Built on Microsoft Copilot Studio, Azure AI Search, and OpenAI GPT models. 🔄 Workflow Automation — End-to-end process automation across your CRM, ERP, and SaaS stack using Make, n8n, and Power Automate — built to scale, not just work once. 🔌 Deep System Integrations — Connecting tools your team already uses: HubSpot, Salesforce, Slack, Teams, Zendesk, Notion, QuickBooks, Shopify, and more. 📊 AI-Augmented Analytics — Embedding AI into your data pipelines for real-time summaries, anomaly detection, and decision-support dashboards. 🛠️ Copilot Studio Solutions — Domain-specific Microsoft Copilot apps with Azure AI Search, grounded in your internal knowledge base for accurate, policy-aware responses. Results From Recent Projects Built a Copilot RAG assistant for an insurance firm that answers policy queries across 100,000+ internal documents — eliminating hours of manual search for their operations team.
