About me

My journey in technology, which began in 2020 and solidified in 2024 with web development, culminated in 2025 with a passion for Ruby and Ruby on Rails. Since then, I've worked as a Fullstack Developer, building scalable and efficient web solutions that aim to positively impact people's lives.

I'm driven by the ability to transform ideas into functional applications, with an unwavering commitment to excellence and a keen eye for clean code and good architecture. I have hands-on experience developing clean, well-designed Ruby on Rails applications using PostgreSQL and SQLite3 for data management. I'm proficient in front-end development with JavaScript (ES6+), HTML5, CSS3, and modern tools like Hotwire (Turbo and Stimulus.js) and Sass/SCSS.

My expertise extends to deploying and managing applications in Linux (Ubuntu) production environments. I have proven skills in configuring web (Nginx) and application (Puma) servers, implementing HTTPS with Certbot/Let's Encrypt, managing dependencies with rbenv and Bundler, and configuring services with Systemd. I highlight my strong debugging and troubleshooting capabilities for complex infrastructure and connectivity issues (including 502 Bad Gateway, HTTPS redirect loops, and socket/port access).

In my day-to-day work, I apply Git best practices for version control, work with the Agile (Scrum) methodology, and am experienced in system debugging. My development environment includes WSL2/Ubuntu and VS Code. I'm a fast learner with excellent communication skills, open to feedback, and strong organizational and project management skills.
