Manikanda Das K
About this gig
Need a fast, scalable backend or web portal? I specialize in building robust backend systems, secure RESTful APIs, and custom web applications using Python, Django, FastAPI, and Flask.
Whether you require high-concurrency microservices, complex relational database design (PostgreSQL/MySQL), asynchronous background queues (Celery/Redis), or seamless third-party integrations (Stripe, PayPal, Auth), I deliver clean, production-ready code built for performance and maintainability.
- High-Performance APIs: Secure, validated endpoints with auto-generated documentation (Swagger/OpenAPI).
- Database Architecture: Optimized schemas, indexing, and query tuning to prevent bottlenecks.
- Authentication & Security: Role-based access control (RBAC), JWT, OAuth2, and data protection.
- Background Processing: Scalable worker queues for email automation, report generation, and data syncing.
Every order includes well-commented source code, clean architecture, and responsive communication from start to finish. Lets discuss your project requirements!
