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.
VENDE FÁCIL — Everything in your town, in one cart.
I built Vende Fácil — appvendefacil.com — a free, hyperlocal marketplace for small towns in Santa Fe, Argentina.
The problem is simple: big platforms take the money out of town. Your local greengrocer, the bazaar, the artisan — they don't have an easy way to sell online. And neighbors end up buying from 5 different places.
The idea: you only buy and sell inside your own community. If you're in Las Parejas, you only see Las Parejas. If you're in Armstrong, only Armstrong. Money stays where it's made.
What makes it different:
• One cart, many stores: veggies from the greengrocer + something from the bazaar + something else from another shop — it all arrives together, in one delivery. • Built to create work: anyone can sign up to deliver in their own city. • Free forever for artisans: makers get a free storefront 365 days a year. Zero commission. • Services with no commission: electricians, hairdressers, cleaners, teachers — they can list what they do for free.
The character: I created a friendly little yellow chick as the mascot. I wanted tech to feel like a neighbor, not a corporation.
Live now in: Las Parejas, Armstrong, Las Rosas, Montes de Oca, Cañada de Gómez, Funes, Rosario.
It was built for one reason: to grow local sales so the big platforms don't take the town's money.

"Money stays where it's made" is such a strong pitch for a small town. One cart from several local shops in a single delivery is the part big platforms can't copy. How are you getting the first shops on board?
