Freelancer profile translated to English.

Description

I design and deliver end-to-end mobile applications and web products, with a specialization in AI integration: scoping, development, payment, and deployment.

Two products in production, built solo:

• React Native / Expo mobile application backed by a Python FastAPI API, with AI content generation (LLM) and safeguards, premium subscriptions, and multilingual content.

• axisapps consultation: Real-time assistance SaaS (Next.js on Cloudflare Workers, Supabase, Stripe), live audio transcription, and LLM pipeline, trilingual FR/EN/ES, GDPR compliant.

What I do for you:

• Mobile applications: React Native / Expo, iOS + Android + PWA

• Pragmatic AI integration: LLM (Claude, GPT, Llama), real-time transcription, RAG, pipelines with safeguards

• Full MVPs and SaaS: Next.js, TypeScript, Node.js, Supabase/PostgreSQL, Stripe

• APIs and integrations: REST, webhooks, OAuth, Cloudflare Workers

My working method: short iterations, regular demos, strict and tested TypeScript, and the obsession to deliver in production, not mockups.

Background: 11 years in market finance (BNP Paribas), now a data engineer. Response within 24 hours. Full remote.

First free consultation to scope your needs.
