Mission
Building B2B SaaS solutions and automation platforms for agency clients. The mission covered five products shipped to production, intelligent scraping systems and generative AI integrations.
I built Prospect-Pro (AI-augmented B2B prospecting platform), RunWeek (connected sports tracking across multiple brands), HomeEnergy (energy calculations SaaS), MailCraft (newsletter creation with PDF generation) and an automated data enrichment platform.
In parallel, I designed advanced automation pipelines: intelligent scraping (Pages Jaunes, Pappers, GoAfrica, Google Maps), N8N + MailWizz automated campaigns, and an automated phone call system via Vapi + SIP. The period also produced three published NPM packages around N8N.
Challenges
Industrialiser plusieurs produits SaaS en parallèle sans dérive de qualité
Construire des nœuds N8N réutilisables et publiables sur le registry public
Gérer le scraping légal à grande échelle sans pénaliser les sources
