I will debug and fix a small java jsp or sql issue
Juan Carlos C
About this gig
Have a reproducible Java/JSP error or SQL query issue? I will investigate one focused problem, explain the cause and provide a contained correction.
My background includes around three years working with enterprise Java, JSP, SQL and legacy business applications, plus practical exposure to Spring Boot and testing tools.
Basic: one issue, up to 2 relevant files. Standard: one issue, up to 5 files. Premium: one issue, up to 8 files, with basic tests or verification notes. Every package includes a patch and a brief explanation.
Please message me BEFORE ordering with the error, expected behavior, reproduction steps, stack versions and a minimal code sample so we can confirm scope.
This service excludes full application development, production access/deployment, security-sensitive changes and completing academic assessments. Remove secrets and personal data from samples. Share only code you are authorized to provide. AI tools may assist analysis; the correction will be checked against the agreed reproduction case.
