Project details

I will build a secure, maintainable REST API using Python, FastAPI and PostgreSQL. The service includes up to five endpoints, relational database models, request validation, automated tests, interactive API documentation and complete source code. I can implement CRUD operations, authentication-ready structures, integrations and business rules based on your requirements. You will receive organized code, clear setup instructions and a concise technical delivery summary.

Backend Developer | Python, FastAPI, APIs & PostgreSQL

I build reliable backend systems, REST APIs, automations and data solutions with Python, FastAPI, PostgreSQL and Node.js.

I can help you:
• Design, build or improve REST APIs
• Automate repetitive workflows and integrations
• Create ETL pipelines, SQL models and analytics backends
• Implement authentication with JWT, RBAC and multi-tenant data isolation
• Add automated tests, Docker setup and clear technical documentation
• Connect a React/TypeScript frontend when a full-stack delivery is needed

Recent project results include an analytics platform processing more than 500,000 sales across 50 stores, a multi-tenant SaaS with 28 API routes and 32 automated tests, and a project management system with 23 REST routes, JWT authentication, role-based permissions, Kanban workflows, email alerts and PDF reports.

My core stack includes Python, FastAPI, PostgreSQL, MySQL, SQLite, SQLAlchemy, Node.js, Express, TypeScript, React, Docker, pytest and Git.

I communicate clearly, confirm requirements before implementation and keep clients updated throughout the project. My goal is to deliver organized, maintainable code that solves the business problem without unnecessary complexity.
