I will develop your python fastapi API or react feature fast
Illia Black
Informazioni su questo servizio
Need a feature built fast without sacrificing code quality?
I will develop a production-ready feature for your Python, FastAPI, React, or TypeScript application with a focus on clean implementation and fast delivery.
I can help with:
- Python / FastAPI backend development
- REST API endpoints and integrations
- React / TypeScript features
- Database logic and SQL
- Frontend-to-backend integration
- Authentication and business logic
- Third-party API integrations
- Fixes required as part of the implementation
- Testing and validation
I have 4+ years of software engineering and QA experience working with backend systems, APIs, databases, automation, and complex production flows. This means I don't just implement the feature I validate the complete flow and look for issues before delivery.
My focus is simple: clear scope, fast turnaround, working code.
Tech: Python, FastAPI, React, TypeScript, REST APIs, SQL, Git, Postman, Selenium.
Please message me before ordering if your task is complex. Send the requirements or repository details and I can quickly confirm the right package.

Please send a clear description of the feature, expected behavior, tech stack, and relevant source code or repository access. API documentation or screenshots are also helpful.

Yes, for small and clearly defined tasks. Send me the requirements first and I will confirm whether 24-hour delivery is realistic.
3. What technologies do you work with?
I primarily work with Python, FastAPI, React, TypeScript, REST APIs, SQL, Git, and related web technologies.
4. Can you work with an existing codebase?
Yes. I can implement new functionality in an existing project, follow its architecture and coding conventions, and integrate the feature with existing APIs and databases.
5. Do you test the feature before delivery?
Yes. I validate the implemented functionality, API behavior, integrations, and relevant edge cases before delivery.
