Looking only for contract work | 0-to-1 Development | Rails developer (12+ years) | Sidekiq | RabbitMQ | Hotwire, Stimulus and Turbo | CTO | 0-to-1 Apps

I’m a Rails developer with over 12 years of experience in software development, including 10+ years working hands-on with Ruby on Rails. Along the way, I’ve built all kinds of applications—automation tools, ERPs, inventory management systems, insurtech platforms, social media apps, and even AI-integrated solutions. I’ve always focused on creating large-scale, high-performance apps that can handle thousands of concurrent records without breaking a sweat. I’ve worked with both SQL (PostgreSQL, MySQL) and NoSQL (MongoDB) databases, making sure they’re set up for speed and scalability. On the backend, I’m well-versed in Sidekiq and RabbitMQ for background processing, and on the frontend, I use tools like Hotwire, Turbo, and Stimulus to make apps fast and interactive. When it comes to deployment, I’ve got plenty of experience with Google Cloud, AWS, and Fly.io, which lets me build infrastructure that’s as reliable as it is scalable. The recent apps I've developed have included AI integration with OpenAI and Anthropic APIs. At present, I'm also setting up an internal LLM for speeding up software development. What makes me stand out? I code fast. Really fast. I’m great at taking an idea from zero to a fully functioning app in just days, without cutting corners on quality. Having worked in Asia and Europe, I’ve learned how to adapt to different clients and challenges, which helps me deliver exactly what’s needed, every time. Recently, I co-founded my own software consulting firm, where I get to use my skills and experience to help businesses grow and succeed. Outside of coding, I’m passionate about dogs, I love solving crosswords, and I’m a bit of a political nerd. These hobbies keep my mind sharp and my creativity flowing, which is probably why I enjoy tackling complex coding challenges. I know Ruby and Rails inside out, and I thrive on turning big ideas into reality—quickly and efficiently. If you need someone who can hit the ground running and deliver results, I’m your developer.

1.5xp | Ruby enthusiast 🌱 | My heart project: @Youclub | My SaaS : @Musicast

🌱 1.5 years experience as a developer (Permanent, Entrepreneurship, Freelance) Depozen: Permanent contract, I was focused on notifications and API integrations. Youclub (activities/clubs search engine): Initiated by my frustration with inefficient Google searches for local clubs, I envisioned and developed a dedicated app using a Ruby GraphQL API and React Native client, with web views integrated into the Rails codebase. Challenges : finding an API to query for to seed my app. Ensure data integrity between models and graphQL types. Challenges were about improving performance of query . Still improves to make. Despite its potential, it was a commercial failure, leading me to flush the database and remove it from Heroku. I later redeployed it in its MVP state for demonstration purposes. Co-founded Musicast: A platform for music competition organizers. After my co-founder departed due to loss of faith in the project, I continued alone, securing early clients before coding the entire SaaS from scratch. This included features like user roles, workflows, AI capabilities, and a dynamic planning generator which I believe is my most complex work due to its customizable settings. I chose not to commercialize it as handling customer support, marketing, sales, product design, and coding alone was overwhelming, particularly in a niche market. This led me to resume my job search. Recently: Diving deeper into Ruby methods to better understand how it works under the hood. Last very interesting moment was re-coding the belongs_to method in Rails with TDD. Current Learning: Diving into Swift during my free time to expand my mobile development skills. (Stanford course) Interests: I have a thing for projects with a mobile component. I am keen on tackling larger-scale projects and deeper Rails functionalities, areas I haven’t explored in my personal projects. Improving performances is an area that I like too. I attend every Paris.rb and React Native Paris events. Career Aspirations: Looking for a collaborative team with structured processes, code reviews, and a senior mentor to further my growth.
