Over the past six years, I have honed my skills in Ruby on Rails, utilizing technologies like Hotwire or React for the frontend. The versatility and elegance of this framework have captivated me, making it my go-to choice for building robust web applications. In addition to my expertise in Ruby on Rails, I have also immersed myself in the world of Python Data Science libraries, including Pandas, Scikit-learn, and Tensorflow. This journey has sparked a deep interest in Natural Language Processing (NLP), and I am eager to explore innovative applications in this field. Beyond my development work, I am a teacher at Ada Tech School, an inclusive institution dedicated to fostering diversity within the tech industry, and Nao School, a bootcamp in Data Science. I am excited to learn more about your projects and how I can contribute my skills and enthusiasm to their success.

With a creative background, I dove into Ruby six years ago for a project related to my original profession. I got hooked and have been coding daily ever since, working on various personal projects published on the web. These projects have had varying levels of success, but they inspired me to transition into a professional career in development. In 2024, I earned both the Silver and Gold Ruby Association Certifications (June and October, respectively), which solidified my passion for venturing into the Ruby world professionally. I work with the classic stack, including Stimulus/Hotwire on the front end, but I’m more than happy to jump on the React or Vue train when needed. When it comes to deployment, I’ve used PAAS platforms and direct setups with SystemD services running Foreman processes behind Nginx. Testing? RSpec is my go-to. Along the way, I’ve harnessed classic utilities like Redis for key-value storage, Vips for faster image processing, and, of course, relational databases.

I started learning Ruby 10 years ago when a specific problem needed to be solved at a retail company. Since then, I have continuously leveraged the potential of this exceptional programming language. Currently, I am training in AI-assisted automation to optimize the resolution of time-consuming problems. I am passionate about learning new skills. I have always had a keen interest in acquiring new knowledge and consistently find ways to apply what I learn to solve problems or improve processes. I take a great interest in deeply understanding the products I work with, which allows me to find the best solutions to satisfy customer needs. Over the past few years, I have used various technologies such as Ruby, Hotwire, Vue.js, Flutter, as well as tools in artificial intelligence, No-Code, and automation.

Hi, I'd be delighted to build your MVP or add new features to your existing Ruby app. From brainstorming to design to implementation, I can jump in at any point and provide constructive feedback or working code, whatever you need. Having worked in the frontend before going fullstack, I'm particularly at ease with HTML and CSS, and I take great care to build responsive and accessible UIs. Backend-wise, I've worked on several document generators, online shops, built blogs, implemented full-text search, and worked with APIs and webhooks, both inbound and outbound. Let's talk!
