"Hi Tom, saw your FastAPI async timeout issues—I refactored Celery task brokers and Redis pub/sub for a fintech API, increasing throughput to 8,500 req/sec."
Why it works: High throughput metric (8,500 req/sec) anchors credibility.

Full Proven Proposal Cover Letter

Hi Tom,

Saw your posting regarding asynchronous worker timeouts in FastAPI. I build high-throughput Python backends.

Deliverables:
- Asynchronous connection pooling via asyncpg.
- Task deduplication and rate limiting via Redis.
- Prometheus metrics exporter for worker latency.

Let me know if you would like to see my open-source FastAPI benchmark.

Best,
Alex
