Crenaly: a booking SaaS I designed and built end-to-end for appointment-based businesses in France: salons, barbers, beauty and wellness.
The core idea: when a client cancels, the freed slot is automatically offered to clients who asked for an earlier time. The first to accept gets it, their appointment moves in place, and the slot they leave is offered next. No double booking, no manual work.
Around it, a full product:
→ Branded booking page for each business, embeddable on their own site
→ Mobile-first booking flow, no account needed
→ Agenda, client management, team roles & permissions
→ Verified reviews, analytics, Stripe billing
Automatically offering a cancelled slot to the next client is such a practical feature for salons and barbers. Designing and building Crenaly end to end must have made those flows much tighter.
I’m a senior full-stack developer and technical consultant with experience in C#/.NET, PHP/Laravel/Symfony, TypeScript/Angular, APIs, SQL, e-commerce and AI integrations.
I enjoy turning business requirements into reliable applications, integrations and practical AI-assisted workflows. I’m currently available for remote freelance collaborations and happy to connect with other builders, founders and teams here on Contra.
