Requirements:
Core Technical Stack: Strong hands-on production experience with Ruby on Rails and SQL databases (PostgreSQL or MySQL).
Frontend Proficiency: Solid experience with React.js, modern JavaScript, HTML5, and CSS3.
Cloud & DevOps Basics: Familiarity with deploying and managing Rails applications on cloud environments (AWS, DigitalOcean, Heroku, or similar).
Remote Competency: Resourceful, disciplined, and comfortable working asynchronously with high autonomy.
Communication: Excellent written English skills for code documentation, issue tracking, and team collaboration.
