Marcelo Zapata
Software engineer.
Software systems for data, automation, research workflows, practice, and review.
I build tools for real workflows: data automation, QA systems, internal tools, reporting, AI-assisted review, and practical interfaces that help teams work cleaner.
Outside work, the same pattern shows up in FSU Options Research, Rally, and AI Workflow Systems: practical builds for research, practice, structured review, and clearer decisions.

Clear tools
Software should help people do the work without making the work louder.
Human feel
The best tools feel obvious after you use them once.
