Freelance full-stack developer
From scoping to production: a first version your users can test, maintainable code and clear communication.Remote — based in France, working with clients worldwide.
About
I build my own web products — SaaS, e-commerce and AI interfaces — and help other founders ship theirs. I’m based in Occitanie, France, and work remotely with clients in Europe and beyond.
The seven case studies below show products I designed, built and deployed from idea to production. When a project is an adapted demo of a private product, I say so clearly.
My main stack: Next.js, React, TypeScript and Convex. My goal: ship fast, communicate clearly and leave you a codebase you can keep building on.
Every engagement starts with an explicit scope: deliverables, responsibilities, exclusions and acceptance criteria.
01
To validate an idea or launch a first version without hiring a full team right away.
Delivered: Scoping, key user flows, interface, backend, deployment and a documented hand-off.
Timeline: Typical timeline: 2 to 6 weeks depending on scope.
02
To add a useful assistant, agent or automation to an existing product.
Delivered: Testable prototype, integration with your data and tools, guardrails, error and cost monitoring.
Timeline: Scope is defined after a short audit of your flows and constraints.
03
To modernize an interface, take over a fragile codebase or unblock changes that have become risky.
Delivered: Diagnosis, prioritized plan, progressive upgrade and validation of critical user flows.
Timeline: The takeover happens step by step to preserve what already works.
Need something smaller? Audits and Claude Code / Codex coaching are also available as add-on support.
Seven selected products showing the problem solved, the solution built and the technical choices behind it.
US Christian art store: 140 prints of Gospel scenes in three painting styles, personalization with preview, framing and print-on-demand shipped across the United States.
Technical highlights — English, US-dollar e-commerce built on ecom-platform: pricing per size and frame, personalization with print files, Stripe payments, Prodigi production and an admin studio.
Private code — it powers Sower & Light and Brûlerie Méridienne.
My reusable e-commerce engine: storefront, checkout, customer area, admin, emails and marketing. A new store is created with one command, with its own language, currency, taxes and backend.
Technical highlights — Multi-store monorepo, configurable markets (language, currency, taxes), US sales tax via Stripe Tax, complete English version and Docker deployment on Coolify.
Demo — name and products adapted for this showcase (the real business is kept private).
Modern e-commerce boilerplate for a coffee roaster: catalog, cart, Stripe checkout, a full back-office and an event-driven AI cockpit connected to an agent (Hermes).
Technical highlights — Complete e-commerce flow, administration, payments, and a domain AI that monitors orders, stock and marketing with human approval.
Speech-practice PWA: a patient, non-judgmental AI voice tutor offers short daily activities to people who struggle to speak (intellectual disability, Down syndrome, language disorders).
Technical highlights — Full voice loop (listening, transcription, rephrasing, speech synthesis), guided activities, protected parent area, subscription with free trial and strong data commitments.
Public beta — temporary URL (calories.lovany.fr).
Nutrition-tracking PWA: log a meal in plain language and the AI resolves the foods and macronutrients. Personalized daily targets, barcode scanning, history and trends.
Technical highlights — Installable PWA with built-in AI (OpenRouter), automatic meal resolution, personalized nutrition goals, barcode scanning and passwordless authentication.
Affiliate and comparison hub for AI & SaaS tools: independent reviews, guides and landing pages produced by an AI pipeline, with bilingual programmatic SEO.
Technical highlights — Programmatic SEO at scale, FR/EN internationalization, semi-automated content and data architecture, now served from Coolify/Hetzner.
Public Vercel demo interface of the API Hub managed through Hermes.
Connection API between my AI agents (Hermes) and my products: a single authenticated, documented entry point exposing targeted reads and controlled actions, with audit and human approval.
Technical highlights — Typed routes and OpenAPI docs generated from Zod, scoped API keys, audit log, unified event queue and a voice gateway for Majesska.
Verifiable method
Each step produces a testable result, an explicit decision and everything needed to move forward with no hidden dependency.
Goals, users, constraints, scope and success criteria are clarified before building anything.
A testable version ships early, so decisions are checked against reality rather than assumptions.
Key user flows, accessibility, security and deployment are checked with reproducible evidence.
Code, decisions and next steps are documented so the product can keep evolving.
Describe the context and the outcome you expect. Budget and timeline help me prepare a useful answer — no commitment.
