Ingénieur Développeur Full-Stack Java

$20/hr Starting at $200

I am a Computer Engineering graduate and Oracle Certified Professional, Java SE 17,
with hands-on experience shipping production software for an enterprise client at
Capgemini.

WHAT I CAN BUILD FOR YOU

- REST APIs and backend services with Java and Spring Boot
- Batch and data-integration jobs with Spring Batch: scheduled processing, business
  rules, error handling, retry policies and alerting
- Event-driven integrations over message buses
- Test automation tooling: simulators, stubs and mocks that replace hardware or
  third-party systems in your test environments
- CI/CD pipelines with Azure DevOps, GitLab CI or Jenkins, including SonarQube
  quality gates
- Full-stack delivery with React.js / Next.js and TypeScript on the front end
- Dockerised deployments

RECENT PRODUCTION WORK

- A Spring Batch job consuming RFID inventory events from a Solace message bus into
  a Sybase repository every five minutes, with a business rule engine, chunk-oriented
  processing, error classification, skip and retry, and mail alerting on failure.
  It removed invoices that were being wrongly issued to customers.
- A Java digital twin of a physical RFID reader: a multi-threaded TCP socket server
  with an internal state machine and a Swing control panel. It replaced the hardware
  during QA, gave every tester their own virtual device, and made failure scenarios
  such as network timeouts and hardware errors injectable on demand.
- Automated Jira status synchronisation through the REST API, and the Azure DevOps
  delivery pipelines that go with it.

WHY WORK WITH ME

- Oracle Certified Professional Java SE 17 - verified, not self-declared
- Clean, tested and documented code, explained in plain language
- Fluent in English and French, based in Morocco: same time zone as Western Europe,
  so we work the same hours
- Clear scope, fixed price and delivery date agreed before we start
