Full-stack engineer

New profile

👋 Freelance software engineer and full-stack Rails developer with 15 years of experience. 7 years CTO. My master was in mechanical engineering with orientiation in numerical methods, but I've always been in software engineering - in the web and Ruby on Rails world for the last 7 years, preceded by 8 years in the Java world. Until last year I have been CTO of a SaaS small business for a web/iOS/Android meditation app. I now offer consulting full-stack Rails consulting services to clients. In recent years I've expanded my front-end skills with Hotwire and Tailwind CSS, as visible on the front page of imagineclarity.com and other newer pages on the site. It features beautiful photographic images from Matthieu Ricard which are responsive in their resolution and change with dark/light mode. The layout combines flex and grid, ajax paginated lists, horizontal scroll containers with snap points, and more. The content is bilingual and loaded from a custom-built backend being migrated to Avo. I created part of the marketing copy myself. I've developed and maintained APIs and integrated third-parties such as Stripe subscriptions, Maichimp marketing and transactional emails, make.com automations. After deploying for years with Heroku, I now also maintain applications deployed with Docker on AWS, and deploy a simple app with Kamal as well. Last year I rewrote an Android app using Turbo Native combined with native screens and ExoPlayer. I am familiar with audio production, translation, copywriting, content management, and the basics of digital marketing. The above mentioned meditation app also features my recorded voice for one of the authors in the French version. Back in my early days, I installed and validated the control system for a medical treatment facility with 230 MeV cycloton and 4 treatment rooms (150M€). This lasted 3.5 years and involved 6 routers, 5 servers, 20 workstations, 40 control units & I/O modules, + integration with exernal systems.
