About Safi

Over 10 years of experience transforming complex ideas into scalable products.

My approach goes beyond just code: I build revenue-generating solutions.

As the founder of ProPhoto.app, I scaled this generative AI SaaS from 0 to €10k MRR solo. This experience allows me to support my clients throughout the entire value chain of a modern web project.

🚀 Technical & AI Expertise
  • Frontend & Performance: Advanced mastery of React and Next.js (App Router, Server Components) for ultra-fast, SEO-optimized interfaces.
  • AI Infrastructure: Deployment of models (Stable Diffusion, Flux, LLMs) on RunPod and Vast.ai. Expert in setting up high-performance training (Fine-tuning) and inference environments.
  • Backend & Scalability: Robust architecture, database management, and complex API integration.

💼 Business Vision (SaaS Mindset)
  • Having bootstrapped my own success, I help you avoid common pitfalls:
  • Choosing the most efficient tech stack (Time-to-Market).
  • Optimizing GPU infrastructure costs.

Implementing conversion funnels and technical growth strategies.

Why work with me? I'm not just an executor, but a technical partner. My goal is to deliver a product that works, scales, and meets your business objectives.

    FableFactory

    Primarily used by parents and educators.
    ~€500 MRR (growing)

    I manage the entire product chain, including:

    • Fullstack development (React, Next.js, TypeScript)
    • Infrastructure & deployment
    • Setup of tracking & analytics
    • Acquisition campaigns (Ads, influencers, SEO...)
