Why a Fractional CTO in Paris?

Rapid Decisions

Architecture, tech stack, and security validated by 20+ years of SaaS experience.

Measurable Execution

Short sprints with clear metrics and tangible deliverables every week.

Quick Audits: Conversion, Stack, and Architecture

In 5 business days, I conduct a targeted audit: conversion, technical debt, stack risks (React/Next.js, Node.js, PostgreSQL), and AI automation opportunities. You receive a Loom video + a "3+1 Method™" action plan: 3 quick-impact fixes + 1 strategic insight for the next 90 days.

Audit Deliverables

  • 20-30 min Loom video with detailed analysis
  • 3 quick-wins to implement immediately
  • 1 strategic recommendation for Q+1
  • Estimated potential gains (performance, conversion, costs)
  • Prioritized technical roadmap for 90 days

MVP Agency in Paris: From Idea to Launch

For an MVP in Paris, I apply a "tiny-MVP" framework: minimal testable scope, reusable components, weekly dev sprints, and continuous production deployment. Goal: get market signals in weeks, not months. The "Core Growth" option then takes over to scale key modules (auth, billing, reporting).

  • • Basic auth & onboarding
  • • 3-5 validated core features
  • • Production deployment (Vercel/AWS)

Growth Phase (monthly)

  • • Advanced Stripe/billing integration
  • • Dashboards and reporting
  • • Conversion optimization
  • • Infrastructure and monitoring

React Developer in Paris (FR/EN)

Specialist React developer in Paris and Next.js expert, I optimize performance and DX: routing, server actions, edge caching, and security. I maintain QA discipline (reviews, tests, CI/CD) to avoid debt that slows growth. FR/EN with product & sales stakeholders.
