The independent integration engineer

AI vendors deploy their engineers at their clients' to integrate and keep their product. I'm the engineer you bring in client-side: I implement your AI agents and automations in your processes, on portable building blocks, and I put you in control of your costs and your choices.

The problem

What slows you down, and what we change

Today

  • Your AI solution ties you to a vendor: data hosted at his place, imposed model, recurring prices, difficult migration.
  • The cost of tools and subscriptions repeats every month, forever, even underused.
  • Vendor engineers (FDE) are effective, but they work for their employer, not for you.

With Buildoto

  • I work client-side: your data stays at your place, the building blocks are portable, and you switch providers whenever you want.
  • I turn recurring costs into a one-time fixed-price investment: you amortize, you own, no more rent.
  • I'm independent: a single goal, your independence and your cost of ownership, measured over the medium term.

Independent integration engineer, I deploy at your place AI agents and automations adapted to your processes, on portable, open building blocks. Your independence and control of your costs are the contract, not a sales pitch.

The observation: a vendor's FDE works for its vendor

AI vendors (OpenAI, Palantir, SaaS vendors) deploy their "forward deployed engineers" in companies to integrate their product with client data and workflows. It's effective, and it's exactly what companies expect from these giants: a product that works fast. But a vendor's FDE has one goal, his employer's: keep his product at your place, in his ecosystem, at his prices. Your dependency is his value.

The counterpart, on the client company side: data at the vendor's, an imposed model, accumulating subscriptions, and a migration that gets more and more expensive every year.

The alternative: the independent integration engineer

I work client-side, with the same deployment skills as an FDE, but in your interest. My goal isn't to keep you, it's to deliver to you:

  • Solutions adapted to your processes: AI agents and automations that follow your business, not a product to adopt as-is.
  • Portable, open building blocks: Supabase (PostgreSQL), Cloudflare (Workers, R2, D1), interchangeable AI models (Mistral, OpenAI, others). Nothing proprietary, nothing locked in.
  • A one-time cost instead of rents: your recurring subscriptions become a fixed-price investment you amortize and own.

The method, in three phases

  1. Free audit · 30 min: I get embedded in your context, I map your processes, your subscriptions and your provider dependencies. No commitment.
  2. Fixed-price quote: scope priced on portable building blocks, price and scope signed within 48 h.
  3. Deployment and transfer: I build, I deploy in your environment and I document. You own the code and control your data.

What you keep

  • Your data: at your place, on your infrastructure, not at a vendor's.
  • Your code: delivered, documented, take-over-ready for your team.
  • Your choices: switch AI model, host or provider without starting from scratch.
  • Your costs: one payment, a controlled operating cost, no more rent.

The economic model

The fixed price on a signed scope, no subscription, no seat, no royalty. After delivery, only operating costs remain: AI API and hosting, generally a few dozen euros a month. It's the logic I also put into your tools: replacing recurring costs with a one-time investment, when it makes sense.

We start with a free 30-minute audit: your need, what you have, your subscriptions, and a fixed-price quote within 48 h.
