Back to original languageAbout Jérémy
12 years of experience transforming your ideas into scalable products.
Launching a SaaS or looking to integrate AI into your processes? I bring a 360° vision to your stack: from robust backend architecture to a high-performance frontend interface.
💡 My approach: pragmatism above all
Senior Expertise (12 years): AI can generate code, but it doesn't design sustainable systems. I ensure your architecture is secure, scalable, and easy to maintain.
AI & Automation Shift: Concrete integration of LLMs (OpenAI, Claude, Gemini) and workflow automation via APIs to boost your real productivity.
Focus on Time-to-Market: I use modern standards (TypeScript, Clean Code) to deliver quickly without accumulating technical debt.
🛠 Technical Stack:
Frontend: Next.js (App Router), React, Tailwind CSS, TypeScript.
Backend: Next.js, Node.js, NestJS, Serverless architectures.
AI & Data: LLM API integration, cost and token optimization.
SaaS Ecosystem: Supabase, Firebase, Stripe (Payments), Auth.js/Clerk.
DevOps: Vercel, AWS, Google Cloud, Docker, CI/CD.
🎯 Areas of Intervention:
MVP / SaaS Creation: Complete development, from database to deployment.
Audit & Redesign: Migration of legacy code to Next.js/Node.js to regain performance.
AI Integration: Adding intelligent features (simple RAG, agents) to your existing tools.
Backend Optimization: API redesign, database migration, and security.
My method: Fluid communication, rigorous documentation, and constant focus on user experience (UX).
Immediately available for assignments from 2 weeks to 3-6 months.
📩 Let's discuss your goals: quick response guaranteed.
