● Proficiency in Spring Boot, Spring Data JPA, Hibernate (Java track) or Express.js, async patterns (Node track); comfort working across both is a plus.
● Strong working knowledge of MySQL (master/slave, query optimization) and at least one of Redis, Aerospike, Cassandra, or Elasticsearch.
● Experience with Kafka (producers/consumers, idempotency, retry/DLQ patterns) and/or Apache Storm or similar stream processing.
● Experience building REST APIs, handling distributed transactions, and designing for idempotency and eventual consistency.
● Solid data structures, algorithms, and problem-solving skills.
● Customer-focused, adapts well to change, collaborates across teams (Product, QA, SRE, Partner integrations).
● Proven performer in a high-energy, fast-paced environment; self-starter with minimal guidance.
Good to Have:
● Experience in fintech, payments, or bullion/wealth domains.
● Familiarity with Quartz, Spring State Machine, Resilience4j, or Debezium CDC.

microservices.
