About this gig

Do you need a reliable backend for your web or mobile app? I build clean, well-structured REST APIs with Java and Spring Boot.


I am a Systems Engineer with more than 5 years of experience developing backend services for banks and public institutions in Colombia.


What I can do for you:

  • New REST APIs or new endpoints for your existing Spring Boot project
  • CRUD modules with validation, error handling and pagination
  • Database integration with MySQL, Oracle, SQL Server or MongoDB
  • Integration with third-party REST or SOAP services
  • Bug fixing and improvements in existing Java code
  • Deployment guidance for AWS (EC2, RDS, S3)

What you get:

  • Source code delivered to your Git repository
  • Endpoint documentation
  • Unit tests (Premium package)
  • Clear communication and progress updates

Please send me a message before ordering so we can confirm the scope and the right package for your project.
