FAQ
Which backend language should I choose — Java, Node.js, or Go?
It depends on your project goals. Node.js is great for fast prototypes and APIs with high interactivity. Java is ideal for enterprise-grade, highly secure systems. Go offers top performance and scalability for modern microservices. If you’re unsure, I’ll recommend the best option.
Can you integrate my backend with existing systems or databases?
Yes - I can connect your backend with existing APIs, databases (PostgreSQL, MongoDB, MySQL), or third-party services.
Do you also handle deployment and hosting?
Yes - I can prepare Docker setups, CI/CD pipelines, or cloud configurations (Vercel, AWS, or custom servers).
Will the code be clean and documented?
Absolutely. You’ll receive structured, readable, and commented code with clear documentation for future maintenance.
Can you add authentication and security layers?
Yes - I include modern authentication methods like JWT or OAuth2 and follow OWASP security best practices.
