(03) How hiring works

From brief to first commit.

  1. DAY 1

    01

    Brief

    Give us your Java and Spring versions, the services involved, build tools and the hours you need covered.

  2. DAYS 1-3

    02

    Shortlist

    We share Java engineer profiles with details on Spring, databases and any messaging tools your system uses.

  3. DAYS 3-5

    03

    Interview

    You speak with the engineers about your domain and architecture, and review code samples. Interviews are free.

  4. DAY 5+

    04

    Onboard

    The engineer gets build access, joins your review process and delivers a small, tested change early on.

Java rates depend on seniority, overlap hours and whether you need a lead for architecture decisions. Each engagement is quoted in writing before work starts.

(05) FAQ

Questions, answered.

Which Java versions do you use?

Current long-term-support releases for new work, and older versions when you maintain a legacy system.

Can you work on a monolith that we cannot rewrite?

Yes. We add tests first, then improve it in small steps or carve out services where it pays off.

Do you have fintech experience in Java?

We build fintech platforms on open-source foundations. See the fintech page for the cores we use.

Can I interview the Java specialist before I commit?

Yes. You review profiles, speak to the engineers and choose who joins. Nothing is charged until you confirm.

What if the person is not the right fit?

You can cancel a monthly engagement on two weeks notice.

Who owns the work?

You do. All code, designs and IP belong to you from day one, and work happens in your repositories and tools.

Can your Java engineers work on older Java versions?

Yes. They can maintain Java 8 and 11 systems and plan upgrades to a supported release, adding tests first so the change can be checked.

Do they know Spring Boot and Spring Security?

Yes. Both are standard for them, along with Spring Data and testing tools. They follow the structure your codebase already uses.

Can they work with Kafka or other messaging?

Yes, where your system uses it. They design for retries and duplicates, which is where message-driven systems usually fail.

Can they help with banking or payments integrations?

Yes. They can build services around open source cores and third-party providers, with audit trails. We state clearly what we have and have not delivered before.
