About

Experienced Microsoft Power Platform, Microsoft 365 & Dynamics 365 CE (CRM) cloud/on-premises specialist with a proven history of work in various industries and services.

My experience extends across multiple roles—team leader, consultant, architect, administrator, and developer—implementing solutions throughout Europe. Clients often call me to projects to solve complex and seemingly hopeless problems. I am highly experienced with Microsoft Power Platform, Power Portal, Power Automation, Azure (Microsoft Cloud), cloud/on-premise data integration, cross-mobile platform development with Xamarin (Android, iPhone), MS Office 365/on-premise, and software development leadership.

    As a Technical Architect at NOTIX, I am responsible for mentoring team colleagues who have no prior experience with Dataverse or Dynamics 365. I teach them how to develop and deploy applications, guiding them through the entire solution lifecycle – from design to production. I lead the integration of Power Platform into customer solutions, ensuring seamless connectivity between Dataverse, Power Automate, Power Apps, and other components in real business contexts. I continuously develop my skills toward artificial intelligence and explore how AI can be practically implemented in enterprise environments. A key part of my role is creating Proof of Concepts (PoCs) for new customers, validating technical feasibility and business value before full-scale development begins. I combine deep technical expertise with business acumen to deliver scalable, innovative, and future-ready solutions tailored to each customer's needs.

    Freelance IT Consultant | Specialist in Dynamics 365, Microsoft 365, and Web Application Development I work as a freelancer on various projects, utilizing my expertise in IT, business negotiation, and client engagement. I’ve contributed to Dynamics 365, Office 365 implementations, and web application development, including the complete design and creation of a contract management system for a tool and garden equipment rental business, which operates flawlessly to this day. Over a single weekend, I designed and developed an Outlook add-in for OSKAR (Vodafone's predecessor). I solved Dynamics 365 issues for Schiedel, where the initial solution was unusable due to poor consultant design. I am passionate about creating and executing software projects that leverage Dynamics 365 CE (Sales, Customer Journey...), Microsoft 365, ASP.NET, JavaScript, Azure, and Power Platform. I thrive in negotiating and consulting with clients to transform their software visions into functional solutions tailored to their needs.
