* Demonstrated experience in building scalable and reliable server-side applications with Node.js.

* In-depth knowledge of SQL and hands-on experience with database systems such as SQLite3 and PostgreSQL.

* Familiarity with distributed systems and message queues, particularly Kafka.

* Solid understanding of Java Enterprise Beans and the Spring framework is a significant plus.

* Ability to work independently, take ownership of projects, and deliver high-quality, clean code.

* Excellent problem-solving skills and a proactive, collaborative mindset.

* Good written and spoken English skills.

5. What We Offer

* Competitive Salary: Compensation will be commensurate with your skills and experience.

* Flexible Working Hours: We believe in a healthy work-life balance.

* Professional Development: Opportunities for further training, conferences, and workshops.
