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.

Key Strengths

  • Owned end-to-end delivery of real-time flight operations event processing (batch to streaming)
  • Designed and deployed AWS-based microservice stack (Docker/Kubernetes) with Kafka ingestion and internal APIs
  • Performance and reliability tuning using CloudWatch metrics (retries, dependency timeouts, latency)
  • 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
