Full Proven Proposal Cover Letter

Hi Eric,

Saw your posting regarding sluggish API response times and AWS Lambda cold starts frustrating your international users. I build ultra-fast, zero-cold-start edge backends using Cloudflare Workers, D1 SQL, and KV.

Here is the migration blueprint:
1. Migrate your core latency-sensitive REST routes to Cloudflare Workers (using Hono framework).
2. Set up Cloudflare D1 distributed SQLite database with edge read replication.
3. Configure Cloudflare Cache API for instant sub-20ms cached response delivery across 300+ edge data centers.

I have live benchmarks comparing AWS Lambda vs Cloudflare Workers edge latency. Would you like me to send them over?

Best,
[Your Name]
