The problem

What slows you down, and what we change

Today

  • Your cloud bill and your latency rise with usage: on 1 TB served per month, S3 costs you more than 90 € where R2 only costs around twenty. Every month, that's money lost.
  • A badly architected application is paid for twice: at scale, then in rewrites. Architecture choices are made at the start, not at the end.
  • The risk with AI and the edge: a demo that works, but nothing that holds in production.

With Buildoto

  • The Cloudflare edge: low latency everywhere and egress fees eliminated. The cloud bill drops from the very first month, at a fixed price, no subscription.
  • An architecture already proven in production on beforbuild.com: not a POC, a stack that holds and that your team can take over.
  • We deliver a monitored, documented stack in production. And if the result isn't there, we come back: it's guaranteed in the package.

Freelance Cloudflare Workers developer, I design and deploy edge APIs, serverless backends and AI pipelines on Cloudflare. Stack already in production on beforbuild.com, delivered at a fixed price from €440 excl. tax, no daily rate.

What I build on Cloudflare:

  • Serverless API at the edge: authentication (JWT), rate limiting, webhooks, middleware.
  • R2 for file storage, replaces S3 and cuts egress fees.
  • D1 (serverless SQL) and Durable Objects (real time, shared state).
  • Edge RAG with Workers AI + Vectorize: upload, extraction, embeddings, search.
  • AWS Lambda → Workers migration to cut the bill and the latency.

Why Cloudflare: low latency everywhere in the world, controlled costs, and a single provider for compute, storage and AI. My default when global speed or cost matters.

Observed orders of magnitude: for 1 TB of files served every month, R2 costs around twenty euros where S3 exceeds 90 € because of egress. A Worker starts with no measurable cold start, while a Lambda can take several hundred milliseconds cold.

Who I am

A single point of contact, from audit to handover

I design, develop and run my own features in production: BeForBuild.com, the B2B SaaS I manage single-handedly, is the proof. These proven building blocks, I deploy them in your environment, at a fixed price, and you own them.

You talk directly to the person who delivers: no subcontracting, no agency layer. The one who designs is the one who codes, deploys and hands over.
