Freelance Automation Engineer · Independent
Remote
- Architect and ship production SaaS automation end to end — review-response automation, thread-aware email categorization, and AI ad-creative generation — from data model to operator dashboard.
- Build real OAuth2 integrations (Gmail, Google Business Profile) with refresh-token lifecycles, invalid-grant detection, and near-real-time ingestion via webhooks and Pub/Sub.
- Engineer for throughput and cost: rate-limit-safe concurrency, batched writes, tagged caching, and pre-filtering that skips work before it costs a model call.
- Design draft-to-approve pipelines with structured reasoning logs and per-decision auditability, so automation runs unattended without losing control.
