I build web applications and AI features that hold up in production

Twelve years of demanding interfaces, now from the PostgreSQL database to the React interface. Fixed-scope packages, tests and documentation included.

What I do for you

Four ways to work together, from internal applications to campaign pages.

Custom business applications

  • PostgreSQL database, per-profile permissions, change history
  • Authentication, roles, scheduled jobs
  • Unit, integration, and end-to-end tests
  • Hosting in the European Union, GDPR compliance
When a shared spreadsheet is no longer enough and off-the-shelf software doesn't fit

AI integration in your product

  • Content generation (Claude, OpenAI)
  • Product recommendation and personalization
  • AI pipeline with human approval workflow
  • Automation and publishing via API (Meta, etc.)
To add a concrete AI feature without hiring an ML or data profile

Landing pages & premium campaigns

  • Structure designed to guide toward action
  • Flawless mobile, fast loading
  • Promotional videos and animations
  • Connected to your CRM, analytics, or e-commerce funnel
Campaign pages, product launches, and acquisition pages at the level of major brands

Interactive web experiences

  • Product quizzes and diagnostics
  • Multi-view experiences and gamification
  • Configurators and discovery mechanics
  • Advanced animations (GSAP, Framer Motion)
When a classic landing page is no longer enough to engage your audience

How it works

Three steps. No surprises, no radio silence.

Step 1
Discovery call — 30 min

We define your objective, your constraints, and what has to exist at the end: an application, a feature, a page. No written brief required.

Step 2
Costed proposal in 48h

You receive the scope broken down, what is included and what is not, and a firm price. You approve, we start.

Step 3
Delivery + launch

Development, feedback integrated, launch. You get clean, documented code ready to evolve.

About

Portrait d'Adrien

Twelve years of web development, eleven of them freelance. I've worked in environments where perceived quality and performance are not up for negotiation: Chanel, Fnac Darty, Prisma Media. Today I build complete applications, from the PostgreSQL database to the React interface, with language models built into the product rather than bolted on top. I deliver fixed-scope, with tests and documentation. I work remotely. A two-paragraph brief is enough to get started.

Applications in production

Two AI applications in service, built from the database to the interface.

Bookvox

What it doesSocial content generation for novel authors, live with a first client. The app describes uploaded visuals with Claude Haiku, indexes reference documents for vector search (multilingual Cohere embeddings, pgvector) and drafts posts with Claude Sonnet in the author's own voice.

In productionHuman validation before publishing, drag-and-drop editorial calendar, OAuth publishing to five networks with AES-256-GCM encrypted tokens, multi-tenant isolation per workspace via row level security.

  • Next.js
  • TypeScript
  • Supabase
  • pgvector
  • Claude
  • Cohere
  • n8n

Content Studio

What it doesLinkedIn post production chain driven by three specialised LLM agents: a strategist that frames the request and proposes angles, a writer that drafts the post, and an art director that reviews the visuals and iterates on them.

In productionSystem prompts assembled in TypeScript and versioned with the code, brand context in the database rather than in files, outputs schema-validated before reaching the interface. Streaming via the Vercel AI SDK, fal.ai image generation, Prisma persistence on PostgreSQL.
