I will build a production fastapi backend and rest API
Artem Sarkisian
About this gig
PRODUCTION BACKEND ENGINEERING WITH FASTAPI
Need a backend that can handle real production use, not just a collection of endpoints?
I design and build FastAPI backend systems with architecture, data models, APIs, integrations, reliability and deployment considered from the start.
WHAT I CAN BUILD:
- REST APIs and backend services
- PostgreSQL schemas and migrations
- Authentication, roles and permissions
- External API and webhook integrations
- Redis caching and background jobs
- WebSockets and real-time features
- Validation, error handling and logging
- Automated tests
- Docker-ready deployment
HOW I WORK:
I start with scope and architecture, define system boundaries and interfaces, then implement. You get maintainable source code, a clear structure and documented APIs.
12+ years in software engineering. Former Head of SDET for large financial and high-traffic systems. CTO and systems architect.
Core stack: Python, FastAPI, PostgreSQL, Redis, Docker, REST and WebSockets.
Basic covers a small API or module. Standard and Premium cover larger production backends with databases, authentication, integrations and additional infrastructure.
For larger systems, message me for a custom offer.

My core stack is Python, with experience in Go, Java, TypeScript and Rust. I work with backend systems, APIs, databases, distributed services, AI integrations, automation and trading infrastructure.
I focus on clear scope, sound technical decisions, reliability and maintainable code.

FAQ
What is included in the Basic package?
The Basic package includes a small FastAPI backend with up to 3 REST API endpoints and source code. Database integration, authentication, deployment, and advanced integrations are not included.
What counts as one API endpoint?
One endpoint is one API operation, such as creating, retrieving, updating, or deleting data.
Can you connect the backend to my existing frontend or mobile app?
Yes. I can build REST APIs for React, Vue, Next.js, mobile apps, Telegram Mini Apps, and other clients.
Do you provide database integration?
Yes. PostgreSQL database integration is included in higher packages or can be added as an extra where available.
Can you add authentication?
Yes. JWT authentication, protected routes, and role-based access can be included in larger packages or custom offers.
Can you integrate third-party APIs or services?
Yes. I can connect documented REST APIs, payment systems, CRMs, analytics services, and other external platforms.
Will I receive the source code?
Yes. Source code is included in every package.
Do you deploy the backend to a server?
Deployment is available as an extra. I can deploy the project on one VPS using Docker and configure automatic restart.
What is considered a revision?
A revision is a correction within the originally agreed scope. New endpoints, integrations, features, or architecture changes are additional work.
What if my project does not fit the packages?
I can provide a custom offer based on the required endpoints, integrations, database structure, and deployment needs.
