Today on ILikeIT, I had the opportunity to showcase the platform powering the Romanian National Artificial Intelligence Olympiad. I talked about how it works, how many students submitted solutions during last Saturday's interview, and the types of solutions the platform evaluates. Together with my colleagues, we've built something truly remarkable in under a year: a platform that now supports a national competition where students can explore, create, and genuinely enjoy building what inspires them. The top performers go on to become part of the international team representing Romania, taking their skills and passion to the global stage.

592 builds. Hundreds of decisions. Some features took my apps straight to #1 in their category. Others were quietly buried in a hotfix and never spoken of again.
A brutally honest walkthrough of what actually happens when you iterate a mobile app in production — with real users, real reviews, and real consequences. From features that earned their place, to ones that shipped with confidence and died with a 2-star review, and feedback patterns that changed the direction of the product entirely.

Indie app economics aren't taught in courses; you learn them from cloud bills and failed campaigns.
This isn't a finance lecture, but a decade of experience distilled into practical advice on balancing passion and profit. Drawing from launching over 45 apps since 2016, we'll break down real infrastructure costs, how to turn free users into valuable assets, and why 'cheap' decisions often end up being the most expensive.
