Hi, I’m a Java & Spring developer with 4+ years of experience working on backend systems, REST APIs, SQL optimization, and enterprise applications. I’m comfortable working across: * PLSQL queries, stored procedures, functions, and performance tuning * Java/Spring/Maven/JUnit development and bug fixing * Git workflows including feature branches and pull requests I’ve also worked on performance-focused tasks, debugging production issues, and improving existing codebases while keeping changes clean and maintainable. I can work comfortably with SQL*Plus, IntelliJ, Maven, and command-line workflows, and I pay close attention to clean commits and stable deployments. I’d be happy to discuss the project and start with a small task if needed.

This aligns well with the kind of workflow where consistency matters as much as coding. Moving between Oracle/PLSQL tuning, Java changes, and disciplined Git workflows requires someone comfortable jumping from execution plans to Spring code to clean PRs without slowing delivery. A few quick questions: 1. Which Oracle version and Java/Spring versions are currently in use? 2. Is performance tuning mainly database-side (queries/procedures) or application-side as well? 3. What branching strategy are you using today (Git Flow, feature branches, trunk-based, etc.)? Best regards, Muzammil

We can support your Oracle + Java stack with strong hands-on experience in PLSQL optimization, backend feature development in Java (Spring/Maven/JUnit), and disciplined Git workflows for clean, review-ready feature branches.

@supergana

Hi - I have been associated with java since jdk1.0 and very well versed with the fundamentals of OOPS. I am not uptodate with the latest java script based frameworks, but your JD reads that it is predominantly core java, so i'll be just fine. Similarly in Oracle I have several years of experience. Even as a freelancer I have been supporting a 1.5TB Oracle DB for 6+ years now. Prior to freelancing I worked with Infosys for 2 decades. Freelancing now, due to passion for coding. Thank you.

@serviceaxisgroup

Hi, I can help with error-free Java, Oracle PL/SQL, and Git-ready changes that compile, pass existing tests, and are mergeable. I’d start by reviewing your current PR branches, reproducing any issues, then tracing hot spots with execution plans and targeted Java fixes. To reduce risk, I’ll keep work in small feature-branch commits with clear messages and verify builds and staging runs before you review. Are there specific PL/SQL procedures/functions you want optimized first, or any known slow queries? Which Spring/Maven module or endpoint is most affected right now?

@judeg40

Hello, As a seasoned Fullstack Developer, with expertise in API Development and Java programming, I believe I can make a strong impact on your project. For the PL/SQL development portion, I have significant experience crafting complex queries as well as refactoring stored procedures/functions for optimum performance. I am adept at reading execution plans, indexing, and employing performance hints judiciously to trim milliseconds of execution time in order to achieve optimal application performance. On the Java front, your requirement for new features addition and bug fixing resonates with my love for problem-solving and optimization. I have considerable experience in Spring, Maven, and JUnit while my strong core-Java skills coupled with an eye for performance allow me to identify pain points in the codebase and optimize it effectively. Lastly, my familiarity and comfort with Git ensure that commit messages are clear, branching is sensible, and any "works-on-my-machine" surprises are eliminated. I am well-versed in ensuring clean builds pass existing tests each time a change is made in codebase. I assure you error-free work with minimal new warnings through meticulous testing in a staging environment before final delivery. If you're looking for someone who enjoys solving performance puzzles while maintaining high coding standards, let's discuss how we can bring excellence to your project! Thanks!

Hi there, I am exactly the reliable extra pair of hands you are looking for. As a Software Engineer with a strong foundation in building modular, highly optimized applications, I thrive at the intersection of backend logic and database performance. Here is how I will tackle your day-to-day requirements: Java & Architecture: I write clean, strictly object-oriented core Java. Whether it involves refactoring legacy code, tracing pesky bugs, or adding new features within your Spring/Maven ecosystem, my focus is always on maintainability and performance. I ensure all changes pass JUnit tests seamlessly. Oracle PL/SQL Tuning: I don't just write queries; I analyze them. I am highly comfortable diving into execution plans, applying strategic indexing, and using hints to shave off those crucial milliseconds from complex stored procedures and functions. Strict Git Discipline: You will get zero "works-on-my-machine" excuses from me. I strictly adhere to feature-branch workflows. Every pull request I submit comes with logical, well-documented commit messages and code that is ready to be merged and deployed to staging without warnings. I enjoy solving performance puzzles and keeping codebases clean. I am ready to pull the repository, set up my IDE, and tackle your first bug or optimization task. Looking forward to collaborating with you. Best regards, Mohamed Ashraf
