About

Professional summary

I am a Data & Automation professional specializing in end-to-end solutions for process automation, data processing, transformation, systems integration, and operational optimization.

I combine a strong accounting, financial, and administrative background with technical skills in Python, SQL, Power Automate, Power BI, APIs, and document-processing technologies. This allows me to understand business logic, identify inefficiencies, and turn operational requirements into practical technical solutions.

I have experience automating financial, banking, tax, and healthcare processes. My work includes extracting, cleaning, transforming, validating, and integrating data from PDFs, images, emails, Excel files, APIs, databases, and management systems.

I develop and maintain end-to-end automations using Power Automate Desktop, Power Automate Cloud, Python, and SQL. I also provide production support, investigate incidents, resolve technical issues, and document solutions for continuous improvement.

I work directly with clients to gather requirements, answer technical questions, and monitor incidents. I contribute functional and technical knowledge to identify exceptions, inconsistencies, and automation opportunities in administrative and financial workflows.

I am continuously expanding my skills in Data Engineering, Cloud, and Artificial Intelligence, with a focus on intelligent automation, data integration, cloud infrastructure, and AI agents applied to business processes.
