You're in the right place if...
The profiles I work best with
You're launching your startup
You raised (or you're bootstrapping), your product vision is clear, but you need to accelerate without hiring a complete tech team. You want a rapid MVP and scalable architecture.
Seed/Série AMVP en 15jTech scalable
You're an overwhelmed CTO
Your team is drowning in requests, the roadmap keeps growing, and you need senior reinforcement to unblock strategic projects. You want someone autonomous who understands quickly.
Renfort seniorAutonomieCode review
You're a non-tech founder
You have business expertise and product vision, but not technical skills. You want a tech right-hand who speaks business and can handle development end-to-end.
CTO as-a-serviceVision 360°Recrutement
You want to industrialize your tech
Your business is running, but your tech can't keep up. You want to automate, integrate AI, and professionalize your infrastructure without breaking everything. You're looking for someone who understands legacy constraints.
