Freelancer profile translated to English.
Back to original languageAbout Baptiste
After 6 years of experience in aeronautics (test engineer then systems study manager at Airbus), I decided to reorient myself towards computer programming, which I have been practicing for about ten years.
I support you in your projects as a web developer, both on the back-end part (Ruby on Rails) and front-end (HTML/CSS/JavaScript), as well as for the deployment and production of your applications.
I master all the following technologies & tools:
✔︎ Back-end: Ruby 3, Rails 7
✔︎ Front-end: HTML5, CSS3, Bootstrap
✔︎ Front-end & UI Optimization: Hotwire Turbo, JavaScript (Vanilla & Stimulus)
✔︎ Database: SQL, PostgreSQL, Metabase
✔︎ Versioning & Deployment: Git, GitHub Actions, GitLab Pipeline, Heroku
✔︎ Tests: RSpec, Capybara, FactoryBot
✔︎ Performance & monitoring: Redis, Sidekiq, Sentry, Bullet
✔︎ Authentication & security: Devise, Pundit
✔︎ Prototyping: Figma, Whimsical
✔︎ SEO & data analysis: Google Search Console, Google Analytics
✔︎ Content Delivery Networks: Amazon S3, Cloudinary
✔︎ External tools: HubSpot, Stripe, Brevo, Mandrill
✔︎ Project management: PivotalTracker, Slack, Notion, Trello
Here are the main development steps in which I am involved:
✔︎ Realization of ideas through rapid prototyping (MVP)
✔︎ Transition from an MVP to an industrialized and scalable version
✔︎ Design of data models
✔︎ Creation of responsive websites
✔︎ Addition and enrichment of features (front-end and/or back-end)
✔︎ Implementation of functional, unit and/or integration tests
✔︎ API construction
✔︎ Refactoring
Do not hesitate to contact me: I adapt to your organization (agile or not), your needs and your budget and time constraints!
See you soon,
Baptiste
