**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.**

I help businesses automate operations with AI agents, workflow automation, and API integrations. I build reliable systems for lead routing, CRM updates, internal copilots, RAG bots, and multi-step automations using Zapier, Make, n8n, Python, and custom APIs. My focus is not just building the workflow, but making it stable, measurable, and easy to operate after handoff. What we build end-to-end AI lead-routing workflow CRM automation with webhooks and retries RAG/internal knowledge bot API integration / synchronization system How I run delivery Clear scope → fast prototype → measurable outcomes (time saved, error rate down, cycle time down). I document everything, add tests/evals for reliability, and set up production-grade observability (logs, cost/latency, failure monitoring) so your team can confidently operate it after handoff. Deliverables you’ll actually receive Solution blueprint + architecture diagram (agent graph, tools, data stores) Prompt library + guardrails + regression/evaluation suite RAG pipeline with a vector database and citations where needed Automations/integrations with error handling, retries, and clear documentation Handover docs + training (async walkthrough available) If you share your top 1–2 workflows, I’ll map the quickest, safest path to automate them and propose a build plan with clear success metrics.
