About Lotfi

Senior AIFull Stack Developer | Next.js · React · Node.js · TypeScript · Symfony · Laravel

Is your web or mobile project hitting its limits or stuck due to a lack of someone capable of truly driving it forward? That's where I come in.

**16 years of experience**, I design and deliver complete end-to-end applications: e-commerce, SaaS platforms, business applications, and AI solutions, from the data model to the interface, without needing daily supervision.


Recent achievements:
Tech Offer -Intelligent extraction of technical documents using LLM vision and RAG (Claude API), automated quote generation

Droppulse -Product intelligence SaaS with AI agents and pipelines (Claude API), Next.js, and Node.js
Celeste - Headless e-commerce Next.js / React and GraphQL API

Seltygo -Freight platform and React Native mobile application

Pharma-GDD -Pharmaceutical e-commerce, DDD architecture, and secure Worldline payment

What I bring to you:

AI-augmented development. I design and deploy AI agents, LLM pipelines, and RAG systems in production (Claude API, LLM vision, asynchronous orchestration), and I use Claude Code and Cursor daily.
For you: truly functional AI products, faster delivery, and controlled costs, without sacrificing quality.
A modern and performant front-end. Next.js, React, TypeScript, fast, scalable, and user-friendly applications designed to convert.

My stack:Next.js, React, TypeScript, Node.js, Symfony, Laravel, React Native, Claude API, RAG, LLM vision.

Services:Next.js App | SaaS Development | AI Agents & LLM Pipelines | RAG & LLM Vision | AI Integration | React / TypeScript Front-end | Headless E-commerce | Node.js / Symfony / Laravel API | DDD Architecture

    Two main areas of intervention.

    Complex payment integration. Redesign of the Worldline CAWL integration (3DS / PSD2 compliant), fine-grained management of Card-on-File for recurring payments and tokenization. Diagnosis and resolution of production edge cases (ambiguous ECI return codes, front-end exception handling).
    Stack and skills utilized:
    DDD Architecture, bounded contexts, Symfony, Stimulus / Turbo (Hotwire), TypeScript, Worldline CAWL (3DS, PSD2, Card-on-File, tokenization), Git (rebase, merge conflicts, code review).
