Back to original languageAbout Nathan
With over 5 years of experience, I specialize in Ruby on Rails with expertise in API management and infrastructure optimization. I have worked in complex environments and microservices architectures, collaborating with product and design teams to develop high-performing and scalable solutions.
My technical expertise includes:
Backend: Ruby on Rails 7, PostgreSQL
Frontend: JavaScript
DevOps: Heroku, Docker, Git, CircleCI
Architecture: Monolith, Microservices
Cloud & CI/CD: Dockerization, Continuous Integration
Agile Methodologies: Git, Scrum, code evolution planning
In my previous experiences, I managed the design and development of new features in a microservices environment. More recently, I developed a trading bot and a backtesting application with Python, FastAPI, and Docker, thereby strengthening my skills in infrastructure optimization for high-performance environments requiring advanced automation.
I am also a regular user of artificial intelligence tools, such as Cursor, which allow me to quickly learn new technologies and stay productive, while remaining at the forefront of innovation.
Why work with me?
I combine in-depth technical expertise with a strong ability to adapt to new environments.
If you have technical challenges, I would be delighted to collaborate with you!
