Frequently asked questions
Do you build with NestJS, Fastify or Express?
All three. We default to NestJS for large enterprise APIs, Fastify for high-throughput services, and tRPC + Fastify for type-safe full-stack TypeScript with React.
Can Node.js handle enterprise-grade workloads?
Yes. Node 22 with proper clustering, queues and connection pooling routinely serves 10K+ rps per node. We size the architecture to your traffic and SLA, not to the language.
Do you also deploy to Cloudflare Workers / AWS Lambda?
Yes — serverless Node (Workers, Lambda, Vercel Functions) is one of our most common deploys for APIs, webhooks and edge data.
Can you work with our existing Node team?
Absolutely. We embed as a senior pod, contribute via your PR workflow, and bring code review, architecture and on-call discipline to your team.
Do you offer ongoing support?
Yes. After launch we offer dedicated-pod monthly retainers with on-call SRE coverage, security patching and feature delivery.
