Project details
I help businesses save time and reduce errors by delivering clean, structured, and automation-ready data.
If your spreadsheets are messy, inconsistent, or manually maintained, I will clean, validate, and organize your data so it’s ready for analysis, reporting, or automation.
I work with Excel, Google Sheets, CSV files, and Python to ensure accurate formatting, duplicate removal, missing value handling, and logical consistency.
My approach is practical and results-driven: you get clear outputs, reusable processes, and data you can trust.
Ideal for business owners, analysts, and teams who want reliable data without spending hours fixing spreadsheets manually.

Claude Prompt Engineer — Paid 90-Min Test Task → Ongoing Role
Incredible AI Architect and Prompt Engineer. Cecilia completely solved a complex hallucination issue in our Claude pipeline by migrating us to a strictly-typed JSON Tool Schema with a built-in reasoning scratchpad. She also delivered an automated Promptfoo testing suite and implemented Prompt Caching to save us API costs. She thinks deeply about system architecture, writes beautiful code, and communicates proactively.

I help businesses structure their data, automate recurring processes, and build reliable analytics systems that support real decision-making. My approach is practical and business-oriented: I prioritize clarity, efficiency, and solutions that are easy to maintain.
Typical work I deliver:
• Data cleaning, validation, and gap analysis
• Python-based automation and ETL/data pipelines
• SQL analytics and data quality checks on large datasets
• Dashboards and reporting systems for business teams
• Support for applied machine learning and predictive analytics
I have a background in Agronomic Engineering, which strengthened my analytical thinking and my ability to work with complex, real-world systems and datasets. I adapt quickly across industries such as sales, logistics, agriculture, healthcare, and education.
Clients value my clear communication, structured delivery, and reliability. I focus on understanding the problem first and delivering solutions that actually get used in production.
If you need help automating workflows, building data pipelines, or creating analytics dashboards, feel free to message me to discuss your project.
