À propos de ce service

Need a solid backend for your app or platform?


I build REST APIs and backend systems with Python (FastAPI/Flask), following clean, production-ready architecture not quick hacks.


What I can build:

REST APIs with CRUD operations

JWT authentication & role-based access control (RBAC)

PostgreSQL/SQLite database design

Caching with Redis

Background tasks (Celery)

Docker deployment & CI/CD setup

AI/LLM integration (RAG, semantic search)


Why work with me:

Layered architecture clear separation between business logic, data, and API layers

Production-minded: auth, validation, error handling done right

Real portfolio of completed backend systems (e-commerce, fintech, task management, AI-powered services)


Not sure if I can build what you need? Message me first I'll give you an honest answer, not a sales pitch.

Full-Stack Developer with a strong backend focus. I build web applications, REST APIs, and integrations using Python, FastAPI, PostgreSQL, React, TypeScript, and Docker. I can help with authentication, role-based access, database design, Stripe payments and webhooks, automation, admin dashboards, and third-party APIs. I follow a structured process: requirements, planning, implementation, testing, and documentation. My priority is secure logic, maintainable architecture, clear communication, and reliable delivery.
