Hire Java Developers
Java systems tend to outlive the teams that wrote them. A service started on Java 8 with an early Spring release may still be processing orders today, and it now needs a newer JDK, a newer framework and someone who can change it without stopping it.
PWTECH supplies that someone as a dedicated engineer. They use your build server, your code review process and your ticket system, and they take direction from you. We employ them and make sure the seat stays filled.
Java work that suits a dedicated engineer
Enterprise Java has a recognisable set of recurring tasks. A developer who stays with the system handles them better than a series of short contracts.
Spring Boot services
REST controllers, validation, service and repository layers, configuration by profile, and health endpoints through Actuator. New code follows the package layout the project already has.
JDK and framework upgrades
Moving from Java 8 or 11 to a current long-term support release, and from Spring Boot 2 to 3 or later. The second step renames javax imports to jakarta across the codebase, so every library that touches servlets, persistence or validation has to be checked.
Messaging and event processing
Kafka and RabbitMQ producers and consumers with explicit handling of duplicates, ordering and poison messages. Offsets are committed after the work succeeds, not before.
Persistence with JPA and Hibernate
Fetch strategies, entity graphs, batch inserts and second-level caching. We read the generated SQL, because a mapping that looks tidy in Java can still issue a query per row.
Memory and throughput investigations
Heap dumps, garbage collection logs and Java Flight Recorder sessions to find leaks, lock contention and undersized connection pools. Findings come with numbers from before and after the fix.
Splitting or consolidating services
Extracting a module from a monolith behind a clear interface, or merging microservices that were divided too early and now spend their time calling each other.
The Java ecosystem our developers work in

Picking a level for Java work
Java codebases are large and layered. What separates the levels is how much of the system a developer can hold in mind while making a change.
Junior
Implements endpoints, DTOs, mappers and unit tests within an established structure. Comfortable with the language and the IDE. Needs help with concurrency, transactions and anything that crosses service boundaries.
Choose when: your team has clear coding standards and reviewers with time to give feedback.
Mid-level
Delivers complete features including schema migration, integration tests and pipeline changes. Understands transaction boundaries and knows what @Transactional does and does not do. Can diagnose a failing build unaided.
Choose when: the architecture is stable and the priority is getting planned work delivered.
Senior
Designs service boundaries, chooses between blocking code, virtual threads and reactive streams, and leads upgrades that touch every module. Reads thread dumps and garbage collection logs fluently.
Choose when: downtime is expensive, the platform is due a major upgrade, or the design itself is in question.
Starting a Java engagement
Give us the technical picture
JDK version, framework, build tool, application server and the work you want done. A pom.xml or build.gradle file shows the dependency situation at a glance.
Assess the named candidate
One engineer is proposed, with a profile. You run the interview, technical questions included. If they are not right, we suggest another.
Run a bounded first task
A defect with a known reproduction or a single new endpoint works well. It tests the access setup and the working relationship at low cost.
Establish the routine
The developer follows your sprint or Kanban process in your tools. A summary of completed and blocked items is sent weekly. Billing happens once per month.

*160 hrs/month full-time. Rates are indicative for planning, in UAE dirhams (converted from our US-dollar rates at the fixed peg of 3.6725), before VAT where applicable, and depend on seniority, contract length and timezone overlap. Longer engagements and multi-role teams are discounted — ask.
Is this a sensible way to staff your Java team?
We are a good choice when
- You operate Java services that need continuous development and maintenance.
- An upgrade from an old JDK or Spring version has been postponed for lack of people.
- You have architects and leads but not enough developers to carry out the plans.
- You build software for clients and want additional Java engineers working under your direction.
Look elsewhere when
- The whole job is a day or two and will not recur.
- Regulation demands that every engineer works from inside your country or building.
- You require a fixed bid and the requirements are not yet written down.
- You need Android app development. That is mobile work and is priced on the mobile rate.
Java versions, builds and other practical questions
We run Java 8. Is upgrading worth the effort?
Usually, yes. Newer releases bring better garbage collectors, lower memory use in containers, records, pattern matching and virtual threads. The work is mostly in dependencies that relied on internal JDK classes, and we list those before giving an estimate.
What breaks when moving from Spring Boot 2 to 3?
Three things mainly: the minimum Java version rises to 17, javax packages become jakarta, and Spring Security configuration changes style. Libraries that have not published a Jakarta-compatible version must be replaced. We upgrade to the last 2.x release first to clear deprecations.
Should we use virtual threads?
They help services that handle many requests which mostly wait on databases or other services, and they let you keep simple blocking code. They do not speed up CPU-bound work. We test with your real workload before switching.
Do you work with application servers such as WildFly or WebLogic?
Yes. Plenty of Java still runs as WAR or EAR files on an application server. We maintain it as it is, or plan a move to an embedded server if that would simplify your deployments.
Who owns the intellectual property?
You do. All work is committed to your source control. The contract records your ownership and the confidentiality obligations before the first task starts.
What if the engineer leaves PWTECH?
We find a successor and you approve them. The handover relies on what is already in your repository and tracker, which is why we document as the work proceeds.
