Ruby on Rails and Vue.js full-stack developer with 8+ years of experience building SaaS platforms, marketplaces, CRM systems, and healthcare applications from scratch. I’ve shipped production systems handling 1M+ monthly transactions, built a pharma analytics platform used by enterprise B2B clients for over 6 years, and delivered Vue.js and Node.js applications for clients across the US, EU, and UK. 🧠 Backend: Ruby on Rails, Ruby, REST APIs, GraphQL, PostgreSQL, MySQL, Redis, Sidekiq, Apache Kafka, JWT, OAuth2, RSpec (90%+ test coverage), Capybara, Swagger 🎨 Frontend: Vue.js, Vue 3, Nuxt.js, Vuex, Pinia, Vue Router, JavaScript, TypeScript, Tailwind CSS, Hotwire, Stimulus, WebSockets, Stripe integrations ⚙️ Infrastructure: Docker, GitHub Actions, AWS S3, Azure, Heroku, Nginx, Capistrano, CI/CD pipelines What this looks like in practice: → Built and maintained REST and GraphQL APIs consumed by Vue.js SPAs with clean architecture, versioning, and full documentation → Optimized complex PostgreSQL queries, improving performance in systems with 1M+ monthly transactions → Migrated CI/CD pipelines from CircleCI to GitHub Actions, reducing costs while maintaining production stability → Implemented Kafka-based event streaming and optimized data flows in microservice-based systems → Integrated Stripe payments and real-time WebSocket features in Vue.js and Node.js / NestJS applications → Refactored and extended legacy Ruby on Rails systems without breaking existing functionality → Maintained 90%+ test coverage using RSpec and Capybara in production-grade systems How I work: I communicate clearly from day one, define scope before development starts, identify risks early, and keep progress transparent throughout the project. I’ve worked both independently on full-stack products and in distributed teams with async workflows. Looking for a Ruby on Rails or Vue.js developer who delivers reliable production systems, not just code commits? Let’s talk.

A dev’s job is to help the business earn - not burn. I’ve built systems that handle 5,000+ requests per second at peak. Filters that process 10 million items in under a second. And code that runs $10M+ in yearly transactions without a hitch. I’ve been doing this for 9 years. Happy to jump in and help with your project!
