I will fix bugs or build your java servlet, jsp and jdbc backend
Sakib Khan
About this gig
Struggling with a stubborn backend bug or looking to build a clean web app without the bloat of heavy frameworks? I specialize in core Java 8 architecture, focusing on pure Servlets, JSP, and JDBC database connections. Instead of relying on auto-generated code and bloated tools, I write fundamentally sound, highly efficient logic from scratch.
I can help you with:
- Debugging and optimizing raw Java logic (Stream API, Lambdas).
- Resolving routing issues, session authentication, and DAO pattern bugs.
- Configuring secure database connections (JDBC, JNDI).
- Building custom, framework-free MVC modules.
I don't just patch code; I make sure your underlying architecture is clean, fast, and reliable.
Please send me a message with your requirements and codebase before placing an order!

Hi, I'm Sakib, a Java backend developer from Bangladesh. I build REST APIs and backend systems with Java, Spring Boot, Spring Security (JWT/OAuth2), JPA and PostgreSQL/MySQL. I also fix and extend classic Java web apps built on Servlets, JSP and JDBC.
What you get:
• Clean, documented, well-structured code
• Proper validation, error handling and security
• Clear updates and delivery on the agreed date
I deploy my own services on Linux servers with Nginx and SSL, so I can help you go live too.
Message me your project details before ordering.

FAQ
Do you use frameworks like Spring Boot or Hibernate?
My focus for this gig is on core, fundamental Java architecture. I build and debug using pure Servlets, JSP, and raw JDBC/JNDI connections. This ensures your application remains lightweight and you have total control over the underlying logic without the bloat of heavy frameworks.
What do you need from me to start working?
Before you place an order, please message me with a clear description of the bug or feature, access to your source code (a GitHub repository link is perfect), and any relevant error logs or database schemas.
Will the code be easy for me to read and maintain?
Absolutely. Because I code from scratch and do not rely on IDE auto-generators, the logic is highly deliberate and clean. If you want an even deeper understanding, you can select the "Detailed code comments" extra, or we can schedule a live code review where I explain the architecture.
I just have one specific bug in my DAO pattern. Do I need the Premium package?
Not at all. I believe in tackling problems through manageable micro-wins. A single, isolated issue—like a stubborn bug in a DAO pattern, a routing error, or a Stream API optimization—falls perfectly under the Basic package.
Do you handle the front-end design as well?
This gig is strictly focused on backend logic and database integration. While I will ensure the JSP pages connect flawlessly with the Servlets and data models, complex CSS or UI/UX design is not included.
Do I get the full source code?
Yes. You get the complete modified source code with comments, delivered as a zip file or pushed to your Git repository.
