Jason Lequenne, web & mobile developer

I turn concrete needs into digital products that work, and that people enjoy using.
Mobile apps, business tools, booking platforms, brand websites, landing pages and local SEO: I handle the whole project, from understanding the need to launch, and then help it grow.
For Le Hook, a gym in Lille, I built the app that handles bookings between the gym, its coaches and their members, as well as its website. I also co-built DASH, a mobile party game, and created the websites of the In Extremis theatre company and the Diag Ora property inspection firm.
I design the interfaces I develop, so what you approve in the mock-up is exactly what ships. I work in French and English, in person in Lille or over video calls, WhatsApp and e-mail.
What I do
Mobile apps
iOS and Android apps with React Native: bookings, user accounts, notifications, in-app purchases.
Business tools
Custom web apps with roles and access rights, calendars, dashboards and automations.
Websites & visibility
Brand websites, landing pages and local SEO, in Next.js or WordPress depending on the need.
