About Jules

I design and develop complete web applications, from idea to production product.

My specialty: building robust SaaS applications with Ruby on Rails and integrating AI features (Claude, OpenAI API) that bring real value to users.

Specifically, I have created and deployed several personal products — BeatScope, an AI audio analysis platform for music producers, and FlipDesc, a generator of optimized descriptions for online resale.

These projects are running in production with real users, which has exposed me to all aspects of development: architecture, performance, deployment, and iterations based on user feedback.

My main stack: Ruby on Rails, PostgreSQL, Sidekiq, Heroku, AWS S3, Stimulus/Turbo, Claude/OpenAI API.

I can help you build an MVP, add AI features to an existing product, or strengthen a technical team on a Rails project.
