About

Professional summary

I am a Data Analyst and Data Quality Specialist with more than five years of experience working with structured data, validation processes, automation workflows, and operational reporting.

I use Python, SQL, ETL processes, REST APIs, and data integration tools to extract, transform, validate, and synchronize information across business systems. I focus on making data workflows more reliable, scalable, and efficient.

In my data quality work, I have managed and normalized high volumes of clinical data, investigated inconsistencies through root-cause analysis, and implemented corrective actions and validation rules to reduce recurring issues.

I have collaborated directly with stakeholders, QA teams, and operational teams to translate business requirements into practical data solutions. I also create process documentation and support standardized, maintainable workflows.

My analytics experience includes data modeling, dashboard development, KPI reporting, statistical analysis, and data visualization using Power BI, Excel, Google Sheets, Pandas, Matplotlib, and Seaborn.

I am comfortable building automation solutions with Python, n8n, Playwright, and APIs, and I bring an analytical, detail-oriented approach to solving data and operational challenges.

Data Quality Specialist OCLINICALS

I progressed from clinical data processing into a specialized data quality role focused on validating, normalizing, and managing high volumes of structured clinical data. I ensured accuracy, consistency, reliability, and compliance with operational quality requirements across multiple projects.

I investigated data inconsistencies, performed root-cause analysis, and implemented corrective actions to reduce recurring issues. I maintained validation rules, quality-control procedures, and process documentation while collaborating with QA teams to improve workflows and operational efficiency.

I also trained and supported more than 20 collaborators through onboarding, documentation, and performance-improvement initiatives. I used Excel, Google Sheets, Looker Studio, and internal validation systems for reporting, analysis, and quality operations.

Data Automation & Analytical Support Calm

I supported operational data preparation, collection, validation, and automation initiatives while collaborating with stakeholders to understand business requirements and resolve data-related production challenges.

I assisted in building automated workflows with n8n, Python, REST APIs, and SQL to improve data consistency and reduce manual effort. My work included ETL-related extraction, transformation, validation, and preparation of data for operational use.

I integrated and synchronized information across business platforms using the Notion API, WooCommerce API, and OpenAI API. I also contributed to process documentation and workflow standardization to support maintainable automation solutions.
