Senior Backend Engineer / Architect · Technical Lead

remote · italy

  • Own architecture and end-to-end delivery of enterprise backend systems; mentor a team of 5 developers and cut deployment times by 40%.
  • Architected the Triage Alarm Analysis System — AI-driven triage of production errors across distributed AWS environments.
  • Designed a 5-phase LangGraph workflow around Claude-based reasoning: 35% lower inference cost (~7,500 tokens/job) and latency down from 5–10 s to <100 ms via template-based generation.
  • Engineered distributed FIFO job orchestration with DynamoDB atomic operations and Lambda, eliminating race conditions in real-time state sync.
  • Manage cross-account IAM architecture aggregating logs and alarms across 10+ AWS environments.
