I am a Senior Data & Automation Engineer and Solutions Architect specialized in the Tax and Finance domain, dedicated to transforming high-compliance, manual workflows into scalable, auditable, and 'production-ready' systems. My career is built on a foundation of operational excellence, moving from the 'make it work' layer—using Excel, Power Query, and Power BI to standardize complex data—to architecting full-scale ecosystems within the Microsoft 365 stack (SharePoint, Power Automate, Power Apps). I focus on operationalizing insights through centralized governance, role-based workflows, and rigorous traceability. As technical challenges scale, I transition from low-code to robust engineering. I leverage SQL for data integrity and build advanced automations in Python, specialized in document generation and template-driven reporting. This ensures that every solution is versionable, repeatable, and logically sound. When a bespoke user experience is required, I integrate JavaScript to deliver high-performance internal tools and interactive dashboards. Guided by a Lean Six Sigma (Green Belt) mindset, I apply the DMAIC framework to every project: defining the core problem, measuring performance through KPIs like DSO or SLA, and implementing controls that lock in efficiency gains. My core value is bridging the gap between complex tax requirements and reliable data pipelines, delivering results that are not just functional, but audit-ready.

Exceptional freelancer. A genuine expert in a field crowded with pretenders, he far exceeded the project scope, delivered impeccable work, and produced clear documentation that makes ongoing maintenance simple. He anticipated and solved problems, and added valuable improvements I had not expected. Communication and turnaround were exemplary. Professional, reliable, and brilliant to work with. I could not recommend him more and in the future I would not want to waste my time hiring anyone else.
