Frequently Asked Questions
Should we break our Java monolith into microservices?
Only where there is a clear reason, such as parts that need to scale or be released independently. A well-structured modular monolith is often simpler to run than many small services.
Can you upgrade an old Spring application?
Yes. Upgrades are usually staged: raise test coverage, move to a supported Java version, then step through Spring Boot versions, fixing deprecated APIs along the way.
How fast can I onboard a Java / Spring Developers?
Most engagements start within 3-5 business days of a signed agreement. We match you with pre-vetted engineers, run a short intro call, and you can begin the same week.
What engagement models do you offer?
Full-time (dedicated, 40 hrs/week), part-time, hourly, or project-based fixed-scope engagements, whichever fits your budget and timeline.
Can I interview the developer before starting?
Yes. We share profiles and set up a technical interview with your shortlisted Java / Spring Developers before any commitment.
Who owns the code and IP?
You do. All work is delivered under an IP-assignment agreement, so the code, designs, and documentation belong entirely to you.

What does a Java / Spring Developer do?

A Java Spring developer builds backend systems with Java and the Spring Boot framework, common in banking, insurance, logistics and other enterprises that need strong typing, mature tooling and long-term maintainability. You need one to extend existing Java systems or build services that integrate with them.

What they typically own on a project

  • REST APIs and microservices with Spring Boot
  • Data access with Spring Data and JPA/Hibernate
  • Security with Spring Security, OAuth2 and SSO
  • Messaging with Kafka or RabbitMQ
  • Upgrading older Java and Spring versions

When to hire one

  • Your core systems are in Java and need new features or integrations
  • You are splitting a large Java application into services
  • You run an old Java or Spring version that needs upgrading

What to check in the technical interview

  • Ask how they would design transactions and error handling across services
  • Check experience upgrading Spring Boot versions and the Java runtime
  • Ask how they secure APIs with Spring Security
