Profile
Senior backend developer with 6 years of commercial experience, mostly with PHP and Laravel, and solid
full stack experience with Vue.js and React. I have owned the backend of live production systems,
designed APIs and architecture and reviewed code.
I have worked on large-scale platforms with large volumes of data and many active users, where I
regularly optimized slow queries and endpoints, in some cases making them up to 10x faster. I build AI-
powered features into real products and know how to use AI in development in a way that keeps code
reliable and maintainable.
