You will get a Scalable FastAPI Backend with Docker and Payment API

Project details
Looking for a secure, asynchronous, and enterprise-grade backend that won't crash under high load? I will build a scalable REST API using FastAPI, Docker, and cutting-edge production standards.
What is included in my service:
• Scalable Architecture: Asynchronous FastAPI architecture (SQLAlchemy/Alembic) with clean architecture principles.
• Secure Authentication: Bulletproof JWT Token authorization and Role-Based Access Control (RBAC).
• Background Tasks & Real-Time: Celery + Redis background queues for heavy processing and live WebSocket communication (Live Chats).
• Media Processing & AI: Automated compression, watermarking, and AI API integrations (OpenAI, Replicate).
• Crypto Payment Gateway: Full implementation of NowPayments API with secure webhook IPN handling.
• DevOps & Testing: Production-ready Docker & Docker Compose setup, 60+ automated Unit/Integration tests, and GitHub Actions CI/CD.
You will get fully documented code (Swagger/OpenAPI out of the box). Let's launch your backend!

About Vlad
Senior Fullstack Engineer | FastAPI | Nuxt 4 | Vue 3 | Node.js
Molodizhne, Ukraine - 2:12 am local time
My primary tech stack:
• Backend: Python (FastAPI, Django), Node.js, Celery, Redis, WebSockets
• Frontend: Nuxt 4, Vue 3, Next.js, React, TailwindCSS, Pinia, Zustand
• Databases & DevOps: PostgreSQL (PostGIS), MongoDB, MySQL, Docker, Git
Proven Track Record:
• Enterprise e-Commerce Ecosystem (ASBIS Holding): Optimized complex backend business logic, integrated enterprise-level CRMs, and tuned PostgreSQL performance for high-traffic platforms.
• Front-end for AI SaaS Platform (BinomAI): Architected responsive, interactive web interfaces using Nuxt/Vue. Implemented robust state management, strict Zod validation, and role-based access control (RBAC) for moderators.
• Real-time Applications: Deep expertise in setting up background task queues (Celery), live chat systems via WebSockets, and location-based filtering.
I write clean, maintainable, and well-documented code. I focus on the product's business logic and scalability, ensuring your software is ready for rapid user growth.
