About Valentin

Fullstack developer, I design custom web applications and business websites, designed to be both performant, intuitive, and aligned with field needs. I work on web interfaces accessible from a browser as well as their mobile adaptation, to ensure a fluid experience regardless of the medium.

With practical experience in catering and sales, I understand operational challenges and translate functional requirements into effective digital solutions: cash register management, loyalty programs, product catalogs, management interfaces, or dashboards.

I have also worked in complex environments such as game servers, with instance creation automation, load balancing, and behavioral analysis.
Independent, rigorous, business-oriented, I develop truly useful tools, designed to last.

    Development of a dynamic server creation system on demand, orchestrated by a deep learning algorithm capable of predicting load peaks and anticipating capacity scaling,

    Implementation of a player behavioral data collection system (movements, action patterns, timings...) used for the development of a custom anti-cheat based on statistical anomalies and adaptive heuristics.
