Hire dedicated Java and Spring Boot developers
Java developers who join your team full-time. They build Spring Boot back ends for SaaS products, and they maintain older Java EE systems that still run the business.
Skills our Java developers bring
Experience levels: mid-level and senior
What our Java developers build
SaaS back ends
Multi-role APIs with billing, audit trails and email automation.
AI and document features
OCR, data extraction and AI calls built into the Java service, not bolted on.
Integrations
Payments, calendars, email and third-party APIs.
Legacy Java systems
Keeping older Java EE services running while new front ends are built on top.
Some of the Java projects we’ve delivered
Both are real Nebel work. Client names are shared only with their permission.
AI document intake for a legal-tech SaaS
A Spring Boot 3 and Java 21 back end that turns uploaded contracts, invoices and scans into a draft case. Rules fill what they can, an AI model handles the rest, and every value is checked against a quote from the document.
Read the case studyBack end for a US monitoring portal
A Java EE back end behind a rebuilt React 19 portal for GPS and alcohol monitoring, with live alerts, zones and over-the-air firmware updates for the watches.
Start from a sentence or a contract
The dashboard asks what you are working on. Type the job in plain words, or drop in the contract, invoices and change orders.

Taking over an existing Java app?
If your Java system has grown over many years, your developer documents the main services and data flows, adds tests around the risky parts and then builds new features safely. You get a written summary in the first two weeks.
How you work together
Your developer joins your Slack or Teams, works in your repo, and shows up to your standups. You get a short written update every day and a weekly call. Their working day overlaps with US business hours, so standups, reviews and calls happen in your time zone, wherever in the US you are.
Java hiring questions
Do you work on older Java versions?
Yes, including Java EE. We can also move services to Spring Boot and current Java in stages.
Can you add AI features to our Java back end?
Yes. We have built OCR, document extraction and AI assistants inside Spring Boot services, with every AI answer traced back to its source.
Can we interview the developer first?
Yes. You meet and approve every developer before they start.
