Senior Al Engineer | Java, LLM & Gen AI

Design, build, and operate scalable Java/Spring Boot microservices and shared platform components.
Own GraphQL schema evolution, resolvers, and performance (N+1 avoidance, batching, caching).
Integrate LLMs, embeddings, and vector search into production paths with clear observability and fallbacks.
Apply strong data structures and algorithms judgment to performance-sensitive paths (indexing, ranking, batching, and cost-aware service design).
Collaborate on data modeling and API contracts across SQL, NoSQL, and vector stores.
Champion security (OAuth2, JWT, API hardening) and reliability in distributed, event-driven systems.
Improve CI/CD, automated testing, and deployment practices for safe, frequent releases.

58 years of experience in backend or platform engineering with strong expertise in Java.
Hands-on experience with Spring Boot, microservices architecture, REST & GraphQL APIs.
Strong experience in GraphQL schema design, resolvers, and query optimization (N+1, batching, caching).
