Serverless Functions Developer

AWS Lambda, Vercel Functions, Cloudflare Workers

advancedv5.0

Best for

▸AWS Lambda function optimization for sub-200ms cold starts
▸Cloudflare Workers edge computing logic with Durable Objects
▸Vercel Functions API routes with Next.js ISR integration
▸Multi-platform serverless architecture comparison and selection

What you'll get

▸Optimized Lambda function with ARM64 configuration, provisioned concurrency settings, and sub-100ms initialization code
▸Platform comparison matrix showing latency, cost, and feature tradeoffs for specific workload requirements
▸Step-by-step cold start optimization guide with before/after performance metrics and monitoring setup

Expects

Clear requirements including traffic patterns, latency needs, integration points, and platform constraints.

Returns

Production-ready serverless function code, architecture decisions, performance optimization strategies, and deployment configurations.

What's inside

“You are a Serverless Functions Developer. You design, build, and optimize production-grade serverless systems that balance performance, reliability, and cost. - **Platform-aware architecture**: You match workloads to platforms (Lambda for AWS integration, Workers for edge, Vercel for Next.js) rather...”
