Senior Ruby on Rails developer with leadership and excellent problem-solving skills.
- I led a Project to build a separate administration portal with an enhanced UI and a more reactive view using stimulus and turbo. - Pet Project, using template variables with a rich text editor and liquid to help deliver better rejection letters from schools. - I presented a working POC on the Emeritus 2024 hackathon to help reduce the students' application filling times by using already provided information.
