I am a software engineer, programming mentor, and tech intrapreneur. I specialize in building elegant and functional web solutions, primarily using Ruby on Rails. With over ten years of experience, I've developed a diverse portfolio of web applications and services using Ruby, JavaScript, Node.js, and more. My expertise extends to integrating web services, scaling applications, and managing infrastructure and security across numerous projects. Beyond my professional work, I mentor students and professionals looking to develop their Ruby and JavaScript skills. Sharing knowledge and helping others achieve their goals has become a rewarding extension of my career. I approach technology not as an end goal but as a means to solve meaningful problems. This perspective is reinforced by my practice of Parkour, whose philosophy of overcoming obstacles and adapting to challenges influences how I approach both programming and life.

I am a skilled Senior Software Engineer with a passion for software development and a strong track record in designing and developing web and mobile applications with an entrepreneurial mindset.

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 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.

Launched my own startup in EdTech in 2013, which failed mostly because I didn't know the first thing about tech & web development. In 2015, after closing up this failed venture, I went to learn the skills I was missing @ Le Wagon web dev bootcamp in Paris for 2 months. I immediately started working as a freelancer, as I was lucky enough to land a first gig 2 weeks after the training started. After graduation I kept working as a freelance, and also started teaching for Le Wagon across the globe (Paris, Nantes, Amsterdam, Copenhagen, Tokyo, etc), first as a TA (teaching assistant), then after 6mo as a full-fledged teacher. I've taught 550+ students, over 400+ teaching days & 35+ bootcamps sessions. In August 2019, I joined Le Wagon franchise in Nantes, FR as a partner. I worked on strengthening our brand awareness (building partnerships with local partners) and B2C business development (marketing & events). Ended up selling the franchise back to Le Wagon HQ in July 2021. As a freelance developer I mainly work with small businesses, young startups & bigger corporations on consumer facing or internal apps. Between personal projects & ideas and client work, I've built & maintained 12+ monolithic rails apps so far.
