FAQ
Should I choose Node js or Python?
Node.js is ideal for scalable real-time applications and JavaScript-based stacks. Python (FastAPI) is better for data-heavy or ML-related systems. I recommend based on your project.
Can you work with an existing backend?
Yes, I can extend, refactor, or fix existing backend systems.
Which database should I use?
PostgreSQL for structured relational data, MongoDB for flexible schema-based data.
Do you handle deployment?
Yes, I provide Docker-based deployment setup ready for cloud hosting environments.
How do you ensure security?
I implement authentication, authorization, input validation, secure API structure, and best practices.
Do you write tests?
Yes, I can include basic unit and integration tests where required.
What is the delivery time?
MVP backends take 3–7 days, full systems take 1–3 weeks depending on complexity.
