About Florian

Technical Product Manager freelance, 6+ years on complex B2B products.

My recent projects

At Wojo (Accor), I designed and managed the transition from a third-party back-office to an internal platform for 300+ multi-country sites: DB architecture, API contracts written directly with developers, data mapping over several years of history, and all PMS data.

At Barrière, I replaced a 20-year-old legacy CRM with Salesforce, acting as a technical bridge between business stakeholders and external integrators, training 50+ employees.

Independently, I launched Clasea (B2B edtech SaaS), with its first paying customer, using Next.js / Supabase / Stripe stack, with development assisted by Claude Code.

What I bring

Hybrid product / engineering profile: I read specs, write API contracts, and challenge architectures directly with developers.

Roadmap and technical specifications (data models, multi-tenancy, system architecture).

AI workflows in production (n8n + in-house LLM) to industrialize documentation, user stories, and user research.

Stack

**Product**: Roadmap, Discovery, API specs, multi-tenancy, legacy migration.

**Tech**: React, Next.js, Node, Python, SQL, Salesforce (Apex, Lightning), Docker, Supabase.

**Integration**: iPaaS, SSO, Active Directory, REST API.

**AI**: Claude Code, Windsurf, n8n, Python.


Types of missions I am looking for

Building or refactoring B2B SaaS platforms. Migration to a new system. 0 to 1 on a tech product. Also open to large-scale Product Owner / Technical PM Salesforce projects.

Remote-first for over 5 years. Occasional travel possible.
