- 8+ years of deep, hands-on backend software engineering experience, primarily in the Java ecosystem (Java 11+, JVM internals, Garbage Collection tuning, memory management).
- 2+ years of experience as a Technical Lead, actively mentoring engineers, unblocking teams, and driving technical roadmaps.
- Proficiency with Spring Boot, Spring Cloud, Spring Security, and ORM frameworks (Hibernate/JPA).
- Strong production experience with cloud-native architectures on AWS (EC2, EKS, RDS, S3, SQS/SNS, ElastiCache) and a solid understanding of cloud networking and security.
Deep expertise in RDBMS (MySQL, PostgreSQL) including query execution plans, indexing strategies, locking mechanisms, and ACID transaction isolation levels. Solid experience with NoSQL datastores (MongoDB, Cassandra).
- High-Scale Concepts: Strong understanding of distributed caching (Redis/Memcached), rate limiting, building idempotent APIs, and managing state in distributed environments.
- Product Thinking: Uncover the why,challenge assumptions and turn ambiguity into simple, high-impact solutions that translate intent into action.
- Innovation: Challenge the status quo, simplify complexity, embrace new technologies, and turn curiosity → experiment → insight → solution into elegant, reliable, scalable systems that create lasting value.
- AI Engineering: Build practical expertise in AI, LLMs, agents, automation, and emerging technologies to transform engineering workflows with context-aware, evidence-based, reliable, validated, and safely controlled AI solutions.
