🔧 What I Build

  • Distributed Systems — event-driven architectures, Kafka, CQRS, Event Sourcing, Saga orchestration
  • High-Performance Services — low-level systems, custom protocols, data structures, cache engines
  • AI / LLM Applications — LangGraph agents, Claude API, RAG pipelines, multi-agent orchestration
  • Cloud-Native Infrastructure — AWS (EC2, ECS, API Gateway), Kubernetes, Docker, IaC
