Serverless & Edgeby SoftwareCrafting

Service Overview

We design and build serverless and edge architectures for teams who want to stop paying for idle servers and stop being paged about capacity. That covers Vercel and Cloudflare Workers at the edge, AWS Lambda and Step Functions for backend workloads, and the supporting pieces that decide whether serverless is pleasant or painful: cold start budgets, connection pooling for databases that were never designed for thousands of ephemeral clients, idempotency for retried invocations, and observability that works when there is no server to log into. We are equally willing to tell you when serverless is the wrong shape for your workload. Long running jobs, sustained high throughput, heavy compute, and workloads needing large in memory state are frequently cheaper and simpler on containers. Where the fit is genuine, the payoff is real: scaling to zero, per request billing, and deployment that stops being an operational event.

Technologies we use

Key Features

• Serverless architecture design on AWS Lambda, Vercel, or Cloudflare Workers

• Idempotency keys and safe retry behaviour for at least once delivery
• API routes and edge functions with sensible caching policies
• Background and scheduled jobs without a persistent server
• Infrastructure as code using CDK, SST, or Terraform
• Observability with structured logs, traces, and per function metrics
• Cost modelling and per invocation spend attribution
• Staged rollout, canary deploys, and instant rollback
• Secrets management and least privilege function permissions
• Migration path from existing container or server based workloads
