I build AI agents and LLM-powered products that do real work - not demos that stop at a chat window. My strongest work sits where Agentic AI, full-stack JavaScript, React Native, and cloud architecture meet. I connect models to business data and APIs, build web/mobile products, and take them into production. I give agents the context, tools, permissions, failure handling, and human approval paths needed to act safely. AI SYSTEMS I HAVE HELPED SHIP RAVEN HEALTH - AI AGENTS FOR CLINICAL AND REVENUE-CYCLE WORK Clinicians were losing hours to documentation, intake, claim checks, and billing follow-up. I contributed to AI agents that read clinical documents and session data, draft notes for BCBA review, detect claim gaps before denials, and carry revenue-cycle work through validation and tracking. Sensitive actions return to a person for approval. The agents run inside a 300+ clinic platform. I also built Node.js/TypeScript APIs, Python LLM and OCR services, analytics, and offline sync across React Native and React Native Web. Technicians can record sessions without Wi-Fi and reconcile on reconnect. Raven Health reports eight hours saved per clinician weekly, a 98%+ collection rate, and denials below 1%. ETISALAT - CONTEXT-AWARE SUPPORT AGENTS FOR 8M+ USERS Routine account, billing, plan, and troubleshooting requests were consuming support time across disconnected systems. I added AI customer-service agents that use live context to answer questions, classify requests, complete repeatable back-office steps, update customers, and route exceptions to staff. I had already built the complete platform single-handedly: its responsive React website, React Native iOS/Android apps, reusable design system, complex navigation and state, back-end workflows, payments, and telecom API integrations. It now serves more than eight million users, with automation reducing manual support work while people retain control of sensitive cases. VRBO - LLM AUTOMATION ACROSS TRAVEL OPERATIONS Property teams were working across disconnected bookings, documents, guest communication, and reporting. I contributed to LLM-powered document processing, OCR, customer care, and predictive analytics that turned scattered information into faster, more accurate workflows. The AI work was integrated into React and React Native experiences backed by Node.js and AWS, with Java/Kotlin mobile components, SharePoint, and Power BI. The interfaces brought bookings, guest engagement, documents, and operational insight into one product. QR8ED.AI - RAG, MULTI-MODEL ORCHESTRATION, AND VOICE LEARNING Educational videos were abundant, but learners still had to search, judge, and order them alone. As senior full-stack developer and solution architect, I contributed to the AI system that turns a topic and goal into sequenced lessons, quizzes, notes, summaries, and progress tracking. LangChain orchestrates LLM integration across OpenAI, Anthropic, Gemini, and other providers. Pinecone powers vector search and semantic retrieval for RAG. Whisper and ElevenLabs create voice-enabled lessons. I connected those pipelines to a responsive Next.js/TypeScript product with Convex, Firebase, Stripe, and a built-in LMS. WHAT I CAN OWN FOR YOU - Need AI Agents to take action safely? I design Agentic AI with tool use, orchestration, structured outputs, permissions, context, human approval, evaluation, monitoring, and failure recovery. - Need an LLM to work with your data? I build RAG and LLM Integration with OpenAI, Claude, Gemini, LangChain, Pinecone, vector search, OCR, document processing, speech-to-text, and text-to-speech. - Have an AI prototype but no usable product? I build full-stack JavaScript/TypeScript with React, Next.js, Node.js, REST APIs, GraphQL, authentication, real-time systems, integrations, and multi-tenant SaaS. - Need the product on mobile? I deliver React Native iOS/Android apps, React Native Web, offline-first sync, complex state and navigation, native integrations, and production releases. - Need infrastructure that can carry production load? I design AWS serverless and event-driven systems with Lambda, API Gateway, S3, SQS, DynamoDB, CloudFront, IAM, monitoring, and CI/CD. I am an AWS Certified Solutions Architect - Professional with 14 years in production software and experience leading engineering teams of up to ten. My work spans healthcare SaaS, telecom, travel and property operations, edtech and LMS products, fintech, e-commerce, and enterprise systems. I am at my best when an ambitious AI idea has to become a product people can trust and enjoy using. If you are building that - or rescuing a stalled prototype - send the architecture, user workflow, and failure point. I will tell you where I would start.

**When Microsoft business systems are slowing people down instead of helping them work, I step in to fix them.** I’m a **Top Rated Plus Upwork freelancer** specialising in Dynamics 365, Power Platform, integrations, automation and AI. I help businesses improve unreliable systems, replace spreadsheet-heavy processes, repair failing automations, connect disconnected platforms and introduce AI where it can deliver genuine operational value. Clients typically bring me in when: • Dynamics 365 no longer fits the way the business operates • Teams are relying on spreadsheets, rekeying and manual workarounds • Power Automate flows are unreliable or difficult to maintain • CRM, ERP, finance, marketing or operational systems need integrating • Reporting cannot be trusted • An existing Power Platform solution needs redesigning or scaling • AI could remove repetitive administrative or document-processing work ### Dynamics 365 & Dataverse I design, customise and extend Dynamics 365 Sales, Customer Service and Dataverse applications, including: • Model-driven apps • Forms, views and dashboards • Business Process Flows • Security and permissions • Dataverse architecture • JavaScript and command bar customisation • Business rules and automation ### Power Platform & Automation I build Power Apps and Power Automate solutions for approvals, customer submissions, document generation, notifications, scheduled processing, data synchronisation and complex operational workflows. I design automation for **real production environments**, including validation, error handling, duplicate prevention, retries and logging rather than assuming every process will succeed. ### Integrations & Azure I connect Dynamics 365 and Business Central with external CRM, ERP, marketing, finance, telephony and contact-centre platforms using: • REST APIs • Microsoft Graph • Dataverse Web API • Webhooks • OAuth • Custom connectors • Azure Functions • Logic Apps If two systems need to exchange data reliably, I can usually design and build the integration. ### AI & Intelligent Automation I build practical AI solutions using Copilot Studio, AI Builder and Azure OpenAI for: • Document extraction and processing • Classification and routing • Summarisation • PII and sensitive-data detection • AI-assisted business processes • Human-in-the-loop review and approval The focus is not adding AI for the sake of it. It is identifying where AI can genuinely **reduce workload, improve consistency or speed up a business process**. ### Power BI & Reporting I build management, sales, finance and operational reporting using Power BI, Power Query, DAX, Dataverse, APIs, SQL and Excel. I’m particularly experienced in replacing spreadsheet-heavy reporting processes and turning fragmented business data into reporting that decision-makers can actually trust. ### Recent delivery experience • Dynamics 365 solutions supporting multi-brand and multi-location operations • Business Central and third-party API integrations • CRM integrations with marketing, finance, telephony and contact-centre platforms • Complex Power Automate workflows across legal, finance, training, sales and service teams • Power BI dashboards for sales, forecasting, margin and operational performance • AI-assisted invoice, purchase-order and sensitive-document processing • Multi-stage approval and document-review applications • Replacing manual and spreadsheet-based processes with controlled Dataverse solutions I work across the **full delivery lifecycle — discovery, architecture, development, testing, deployment and documentation**. That means you don’t need one person to understand the business requirement and another to translate it into a technical solution. Alongside my **Top Rated Plus status on Upwork**, I’m an **ISO 27001 Lead Implementer and Auditor**, bringing additional security and governance experience to permissions, integrations, data handling, automation and AI solutions. **Have a Dynamics 365, Power Platform, integration or Microsoft automation problem?** Send me a brief description of what’s happening today, what isn’t working and what you’d like the system to do instead. **I’ll tell you how I’d approach solving it.**
