Key Strengths
- Designed and scaled healthcare document-processing backend (OCR + LLM) handling tens of millions of files
- Built reliable, retry-safe pipelines using deterministic IDs, idempotent state transitions, and stage-level completion markers
- Cost and quota-aware workflow orchestration (centralized rate limiting; early triage to reduce OCR/LLM spend)
- Strong migration execution: dual-run validation, automated diff checks, incremental rollout with feature flags and rollback path
- Operational excellence: persisted intermediate artifacts and per-file observability to speed incident resolution and enable targeted replays
- Identified and fixed subtle failure modes (inconsistent state on partial retries) with reconciliation/self-healing jobs
