I’m a Python Backend Developer focused on building reliable APIs, database-driven applications, integrations, authentication systems, and scalable backend services.
My core stack includes Python, FastAPI, JavaScript, TypeScript, PostgreSQL, SQL, Redis, Docker, and Git. I can develop backend systems from initial database and API design through testing, integration, deployment, and performance optimization.

???? ? ??? ???? ????Backend API Development
Design and build structured REST APIs with FastAPI, including validation, error handling, authentication, authorization, and clean API architecture.
Database Development
Create PostgreSQL database schemas, relationships, queries, migrations, and data-access layers with an emphasis on maintainability and performance.
API Integrations
Connect applications to third-party APIs and services, handle authentication, process external data, and build reliable integration workflows.
Authentication & Authorization
Implement login systems, token-based authentication, permissions, roles, protected endpoints, and access-control logic.
Redis & Caching
Use Redis and caching strategies to reduce database load, improve API response times, manage temporary data, and support scalable backend workflows.
Docker & Deployment
Containerize backend applications and prepare services for reliable cloud development and deployment.
Automated Testing
Build automated tests for API endpoints, business logic, database operations, authentication flows, and integrations.
