About this gig

Professional Python backend developer with 5+ years of experience building scalable, high-performance APIs using FastAPI, Django, PostgreSQL, SQLAlchemy, Alembic, Redis, Celery, and AWS services (Lambda, SQS, ECS, ECR, S3, EventBridge etc). I specialize in designing RESTful APIs, database operations, authentication (JWT), authorization, background tasks, and event-driven workflows. I have hands-on experience modernizing legacy systems, building subscription-based platforms, and creating multi-tenant and high-concurrency applications for fintech, e-commerce, and SaaS.



I provide clean, production-ready code with Docker deployment, AWS-based CI/CD setup, pre-commit hooks, and type checking with mypy, ensuring maintainable and reliable systems. I can also migrate legacy systems, integrate third-party APIs, optimize database performance, and implement caching, distributed locks, and asynchronous workflows for large-scale systems.



Whether you need a small backend, full-featured application, or a scalable production-ready system, I deliver high-quality solutions. Lets build your next FastAPI backend with best practices, security, and performance!
