I am a technical leader focused on building high-performance engineering teams and resilient, scalable systems. Currently, I serve as the CTO and Co-founder of Elio Tax (Accès Impôt), where we are redefining tax compliance through high-scale automation and strategic AI integration.

🚀 Growth & Experience:

• Scaling Expert: Previously employee #80 at On Running, where I spent 7+ years helping the company scale from a local startup to a global powerhouse of 4,000+ employees.
• Entrepreneurship: At Accès Impôt, we double our revenue annually with an 80% customer retention rate, focusing on lean operations and technical excellence.
• Focus: I am dedicated to building secure, high-availability systems that thrive in an AI-transformed market. I believe that robust security and granular access control are the primary differentiators for reliable AI workflows.

I am the creator and maintainer of several tools designed to bridge the gap between complex data models and high-performance APIs.

An optimization utility to inspect GraphQL info objects.

• The Goal: I created this to solve the N+1 problem at its root by "looking ahead" at requested fields before executing database calls, significantly reducing latency in complex graphs.

if (lookahead({ info, until: ({ field }) => field === 'product' })) {
  // include product in the query
}

A framework to automatically generate executable schemas from your ORM models.

• The Problem: Writing redundant resolvers and keeping TypeScript types in sync is a major bottleneck.
• The Solution: I built graphql-gene to eliminate boilerplate, ensuring a single source of truth while maintaining strict type safety and high performance.

query mostRecentOrderByStatus($status: String!) {
  order(where: { status: { eq: $status } }, order: [updatedAt_DESC]) {
    id
    status
    updatedAt

    items {
      id
      price
      quantity
      product {
        name
        color

        group {
          products {
            id
          }
          categories
        }
      }
    }
  }
}

A performance analyzer for Nuxt.js applications.
