FAQ
Do you provide the complete source code at the end of the project?
Yes. I always provide the full, production-ready source code upon project completion. The code is structured according to industry standards and includes detailed comments so that any developer can easily maintain or scale it in the future.
Can you work on existing codebases, or do you only build from scratch?
I can do both. I am comfortable diving into existing Java, Spring Boot, or React repositories to fix bugs, optimize performance, or add new features. I can also design and build complete applications from scratch based on your requirements.
What do you need from me to design a custom JasperReport?
To design your report, I will need a sample of the desired layout (such as a PDF, Excel sheet, or hand-drawn sketch) along with your database schema or a sample dataset (SQL/JSON) so I can map the fields and write the queries accurately.
How do you handle large enterprise projects that take longer than 14 days?
For large-scale applications, please use the "Contact Seller" button to message me before ordering. We will discuss your system architecture, break down the features into phases, and I will send you a Custom Offer utilizing Fiverr's Milestone feature so you can pay as each phase is delivered.
Do you assist with deploying the final web application?
Yes. I can help deploy your Spring Boot backend, React frontend, and database to cloud platforms like AWS, Azure, Heroku, or DigitalOcean. Please mention your hosting preferences during our initial discussion so we can include deployment in the project scope.
