I revitalized a 3-year-old commercial real estate website for Miami properties. The original infrastructure and libraries were outdated, creating security risks and blocking new feature development. I performed a complete codebase refactoring and upgraded all dependencies. This involved fixing 59 critical build errors, replacing deprecated functions with modern solutions, and securely reconnecting the database via environment variables. Finally, I wrote comprehensive documentation. The result is a secure, stable, and fully modernized platform ready for future business growth.

Using Claude Code and prompt engineering, I built a custom automation tool to help businesses send highly personalized cold emails at scale. Instead of sending generic mass emails, this system reads contact variables (like name, company, and custom notes) directly from a Google Sheet and crafts tailored messages for each person.
