I help businesses quickly diagnose and fix Java, MS SQL, My SQL, Oracle, API, Tomcat, Linux and production issues. My main focus is troubleshooting existing systems rather than building everything from scratch. I can help with: • Java / Spring Boot / Tomcat • Oracle / MS SQL / database issues • REST API troubleshooting • Maven / JDK problems • Linux / Nginx deployment • SMTP / email integration • Production bug fixing • Performance troubleshooting If your application is failing, slow, unable to connect, or behaving unexpectedly, send me the error log and environment details. I can identify the root cause, explain the problem clearly, and provide a practical fix. Available for both one-time fixes and ongoing technical support.
