Build

AI product builder: I design, build and ship your products.

AI-augmented, with 15 years of development and 8 SaaS to my name: I turn an idea into a product running in production — fast, and without hidden technical debt.

Three ways to work together

AI product build

From zero to launch

I design and build your product end to end — from framing to launch. A solid AI MVP, shipped fast, ready for your first users.

  • Product framing and MVP scope
  • Design, architecture and UX
  • Full-stack development (web + AI)
  • Deployment and handover

Pricing : Fixed price, per deliverable milestone — set at framing.

Fractional AI product engineer

A few days / week

Senior reinforcement on your existing product: I own features end to end, embed AI where it adds value, and ship to production.

  • End-to-end feature delivery
  • Architecture and AI integrations
  • Code review and best practices

Pricing : Day rate, by commitment (days per week).

AI-augmented development

For your team

I help your team ship far faster with AI: tooling (Claude Code, agents), method and guardrails. Velocity gains, without the debt.

  • Audit of your development pipeline
  • Setup of AI tools and agents
  • Team training and coaching

Pricing : Engagement or coaching — on quote.

How I build

  1. 1. Framing

    We clarify the problem, the users and the scope before writing a single line of code.

  2. 2. Design

    Architecture, flows and tech choices — built to ship fast without painting into a corner.

  3. 3. Iterative build

    I ship in increments, AI-augmented. You see the product move forward every week.

  4. 4. Launch & iterate

    Production launch, usage measurement, then we iterate on what truly matters.

The proof: what I’ve already built

Eight SaaS products designed and developed — from the Novera Talent suite to internal tools. It’s my ongoing R&D, and your guarantee that I actually ship.

Let’s talk for 30 minutes: I’ll tell you straight whether it’s buildable, how, and at what cost.
