About Arthur
Backend Developer with a strong focus on Python, API development, and scalable system architecture.
I specialize in building and modernizing backend systems using FastAPI and Django, with a focus on clean architecture, performance, and maintainability.
My experience includes migrating monolithic systems to modular architectures, designing REST APIs, and improving existing codebases through refactoring.
I am used to working in production environments, including containerization (Docker), CI/CD pipelines, and stable deployments.
My approach is pragmatic and results-driven: I focus on delivering reliable solutions that integrate seamlessly into existing systems.
Available from July 2026 for remote or hybrid projects.
