About this gig
Hi, I'm Pavlo - a backend developer with 4+ years building scalable APIs and services in Python, Go, and Node.js.
I specialize in secure, well-structured backend systems - the kind that hold up in production, not just a demo.
What I build:
- REST APIs with FastAPI, Django, or Flask
- - Authentication & authorization (JWT, OAuth, encryption)
- - Database design (PostgreSQL, MongoDB, Redis)
- - Clean, documented, testable code
Real experience: fintech cashback platforms, authentication frameworks, and renewable-energy microservices running in production.
You can count on:
- Clean, documented code
- - On-time delivery
- - Strong communication (English: B2)
Let's build something reliable together.

FAQ
Will I own the source code?
Yes, you gain full ownership of the code and can modify or reuse it as you see fit.
Can you integrate this API into my existing project?
Yes - just send me your project or the relevant scripts, and I'll integrate the new system directly into your existing codebase and folder structure.
What tech stack do you use for the backend?
I build with Python and FastAPI, PostgreSQL/MongoDB for data, JWT for auth, and Docker for containerization. If your project uses a different stack, message me and I'll confirm fit before you order.
How long does a typical system take to build?
Most single systems (inventory, save/load, or dialogue) take 3-7 days depending on complexity. I'll confirm an exact timeline after reviewing your project.
Do you provide support after delivery?
Yes, I offer a short post-delivery support window to fix any bugs related to the delivered system at no extra cost.
Can you work with an existing codebase that isn't well documented?
Yes. I'll review your project first and flag any risks or extra time needed before we start.
