Soheil D.
Python Backend Developer (Expert-Vetted)
Hi, I’m Sam (Soheil), a Python backend engineer with 6+ years of experience building and maintaining production systems. I specialize in Python backends and data-heavy services, helping teams build reliable APIs, optimize performance, and scale existing systems. I work comfortably on both new projects and large, existing codebases. What I can help with: • Backend development with Python, FastAPI, Flask • Designing and optimizing APIs • Asyncio, background workers, and concurrency • Database design and query optimization (PostgreSQL, SQLAlchemy) • Data pipelines, scrapers, and integrations • Writing clean, well-tested, maintainable code • Debugging and improving legacy systems I care about code quality, clarity, and long-term maintainability. I follow SOLID principles, write tests, and document things so other developers can work with the code easily. If you need a reliable backend engineer who can take ownership and deliver, feel free to reach out.
