It’s summer in the Southern Hemisphere, and families in this area are heading to the beach. One of the most amazing places to visit is Florianópolis, known for its vibrant culture and seaside charm. To understand what makes the city’s Mercado Público so special, I built an end‑to‑end data pipeline: scraping Google Maps reviews with Python and Selenium, storing them in PostgreSQL, and categorizing them with Pandas. The insights are visualized in an interactive Tableau dashboard. It's also the first time I used another tool: Beekeeper! This project blends data engineering, sentiment analysis, and business intelligence to highlight how people experience one of Brazil’s most beloved destinations. You can explore my GitHub repo (https://github.com/ciroduro01/floripa_tourism_analysis) for more information. Have a nice week! ♥️

For this week’s #contraquest, I want to share the project that means the most to me. A Data Analysis of the Film Noir Era (1940–1962) On the surface, it’s a data pipeline: raw Excel, Python ETL, Tableau dashboard... The minor reason it’s special is that I stepped outside my comfort zone and used Tableau instead of my usual Power BI. But the major reason is personal. This topic, American Film Noir, takes me back to my last year of high school, when I wrote a monograph on the genre’s Golden Age. Revisiting it now, through the lens of data analysis, felt like reconnecting with a piece of my past. Check it out on my GitHub repo (https://github.com/ciroduro01/Film_Noir_Movies/tree/main), or read the Medium article (https://medium.com/@ciroduro01/shadows-cinema-a-data-analysis-of-the-film-noir-era-1940-1962-b2dd80cde76c).

Cover image for The client’s goal was to
The client’s goal was to enter a new international market with a defined value proposition — but lacked clarity on the required steps. I conducted a focused strategy session with the business owner, structured the full market entry strategy into clear blocks, and mapped every step into my proprietary task management system. I defined timelines, estimated budgets, assigned responsibilities, and outlined the necessary org structure to execute the plan. The client received a complete roadmap, including a mind map in xmind and pdf formats, along with a fully structured Google Sheets action plan.
