Back to original languageAbout Nicolas
My expertise has been built around two structuring experiences.
B2C mass market — iOS application distributed in 11 countries, several million users. Scale constraints, releases without regression, performance on a heterogeneous device park, multi-country support.
B2B / SDK — development of an indoor geolocation SDK in collaboration with the R&D team, and delivery of the final event applications embedding this SDK. Dual role: design of a stable SDK for third-party integrators, and execution up to the final product.
Accustomed to working in international teams, in a multilingual environment (French, English). Strong adaptability to technical contexts, organizations, and product methodologies.
Today, I am the founder of GossipStack, a drop-in SDK for web and mobile that allows adding comments, feeds, @mentions, #hashtags, notifications, and moderation to any application. Quick setup, 100% native rendering, zero infrastructure to manage.
I have a complete vision of the product cycle: design, development, deployment, marketing, business.
