I need Support personal help for day to day tasks related to PLSQL and JAVA. PLSQL: writing complex queries, crafting or refactoring stored procedures/functions, and tuning anything that drags. If you can read execution plans and know how to trim milliseconds through indexing or hints, you’ll feel right at home. Java: the codebase frequently needs new features added, pesky bugs traced and fixed, and the occasional round of ruthlessly focused optimisation. It’s largely Spring, Maven and JUnit, but clean core-Java skills and an eye for performance are what matter most. Git: every change lives in a feature branch and reaches me through a pull request. Clear commit messages, sensible branching and zero “works-on-my-machine” surprises are mandatory. Deliverables for ...

I’m building a back-end platform in Java that relies on Spring Boot and a fully event-driven microservices architecture. Every service publishes and consumes events through our internal broker, so the code must be cleanly decoupled and highly testable. Data persistence will live in MySQL, so each service should expose its own schema and handle migrations automatically. For cloud resources I already have an AWS account configured; the main integration you’ll work with is Amazon S3 for object storage (user uploads, logs, and occasional data exports). What I need from you is a set of production-ready microservices together with the infrastructure scripts that allow me to spin up the environment quickly. Deliverables • Source code for each Spring Boot microservice, wi...
