About
Backend engineer with airline operations domain experience who modernized flight-ops systems from batch updates to real-time streaming on AWS (Kafka + Spring Boot microservices), improving latency and stability through metric-driven tuning and idempotency. Also shipped a production LLM decision-support component using RAG over operational logs and internal procedures, with strong guardrails and an evaluation/regression loop to reduce hallucinations and enforce grounding.

- Improved peak-time throughput via Kafka consumer configuration and increased parallelism
- Implemented idempotency and duplicate-event handling for event-driven systems
- Built production RAG workflow using operational logs + internal documentation with vector retrieval
- Implemented LLM guardrails (confidence thresholds, rule-based validation, deterministic fallback, timeouts/monitoring)
- Established LLM evaluation loop with scenario-based test sets, quality metrics, manual review, and regression prevention
