You will get a REST API with Spring Boot and PostgreSQL (CRUD + Swagger Documentation)


Project details
You will get a fully functional REST API built with Spring Boot and PostgreSQL, including clean code, Swagger documentation, and database integration.
As a Java Backend Developer, I focus on creating production-ready APIs that are easy to maintain, extend, and deploy.
Each project includes:
✅ Entity–Service–Controller architecture (clean, layered design)
✅ Database integration with PostgreSQL
✅ Validation, Exception Handling, and Swagger / OpenAPI documentation
✅ Docker-ready configuration (optional in Advanced tier)
You’ll receive a tested, documented, and ready-to-run backend, ideal for startups, internal tools, or student projects.
Delivery includes:
Source code + README setup guide
Postman collection or Swagger endpoint for quick testing
Clear structure to extend with your own entities
My goal is to help you build reliable and scalable APIs quickly — so you can focus on your business logic instead of configuration issues.

About Vladimir
Java Backend Developer | Spring Boot, REST API, PostgreSQL
Essen, Germany - 1:33 pm local time
After several years of experience as a BI developer and team lead, I transitioned into backend development with Java, Spring Boot, and SQL — combining analytical precision with clean, scalable code.
💡 What I do:
Build REST APIs with Spring Boot and PostgreSQL
Design and document clean, testable backend architectures
Integrate data models and automate data workflows (ETL)
Deploy applications using Docker and create Swagger/OpenAPI documentation
Tech stack:
Java • Spring Boot • REST API • PostgreSQL • SQL • Git • Docker • Swagger • PL/SQL • Data Modeling
My BI background allows me to design APIs that are not only functional, but also optimized for data clarity, performance, and scalability.
I’m currently developing my own SaaS project (Idioms-API) and working on freelance projects that require reliable backend logic and solid database integration.
Let’s build your backend fast, clean, and production-ready.
