I’m Mario. I build digital products.

I started building software in 2020 and have spent the years since on ecommerce stores and booking engines: systems that have to stay fast while real customers and real orders move through them. I like owning the whole product, from the storefront people see to the admin a team works in every day and the servers underneath. Hard performance problems are the work I enjoy most. You work with me directly, in English or Bulgarian, from Sofia and on European working hours.
