Back to original languageAbout Jeremy
Senior developer with over 8 years of experience, I have mainly specialized in creating REST APIs in Python (FastAPI). Throughout my career, I have also worked on web scraping, data pipelines, and backend systems in sectors such as fintech, SaaS, and crypto.
Over time, I naturally took on DevOps aspects: setting up CI/CD, managing cloud infrastructures (AWS, Docker, Kubernetes), and deploying to production. I am used to designing applications from A to Z and bringing them to production.
I have also mentored developers, managed projects, and led teams. This mix of development, infrastructure, and management has allowed me to acquire a comprehensive vision for delivering reliable and scalable systems.
