• Familiarity with messaging systems and asynchronous processing, ideally within the Kafka ecosystem
• Solid knowledge of concurrency and multithreading concepts, including practical application in real-world systems

• Write clean, well-tested, maintainable code across both frontend (Retool) and backend stacks (Java/Spring Boot)
• Take ownership of the reliability, security, and usability of the backoffice system
• Proactively challenge unclear requirements and suggest smarter, more elegant approaches
