Hey there! I'm Viktor Waissmann, a Web Developer from Rio de Janeiro 🇧🇷.
💻 I specialize in Ruby on Rails and React, with experience building and maintaining scalable applications — from designing APIs and modeling databases to implementing automated tests and background jobs.
🚀 I've contributed to production-level apps at companies like Mainô and Um a Mais, where I worked on everything from bug fixes and new features to webhook integrations and background processing with Sidekiq.
🛠 My toolbox includes:
- Back-end: Ruby, Rails, REST APIs, PostgreSQL, Sidekiq
- Front-end: JavaScript, HTML, CSS, React
- Testing: RSpec, Cucumber, Capybara
- DevOps: GitHub Actions, Docker, AWS, Render
- Agile: Scrum, Kanban, Sprints
I love reading, playing Dungeons & Dragons, and grabbing a beer with friends.
