FAQ
What information do you need from me to get started?
I'll need a clear description of your business requirements, the entities/data you want to manage (e.g., users, products, orders), and any specific authentication or authorization rules. If you already have a database schema or API spec, share it — it speeds things up a lot.
Do you use Spring Boot or Quarkus? Can I choose?
Yes, just let me know your preference before we start. If you're not sure, I can recommend based on your use case — Spring Boot is more mature and widely supported, Quarkus is lighter and faster for cloud-native/serverless setups.
What database do you work with?
PostgreSQL and MySQL for relational data, and MongoDB for NoSQL. If your project needs something else, message me first to confirm compatibility.
Will I get the source code and full ownership?
Yes, you receive full source code and full ownership upon final delivery and payment. No licensing restrictions.
Is hosting/deployment included?
The Premium package includes a Docker Compose setup and deployment guide. Deploying to your specific cloud provider (AWS, Azure, etc.) can be arranged as an add-on — just message me beforehand.
Do you provide documentation?
Yes, all packages include Swagger/OpenAPI documentation so you or your team can explore and test the endpoints easily.
