About

A small software studio that takes projects from the first idea to a system running in production.

PapistaCODING is a software studio founded by Bruno Papišta. We build web applications from the backend to the last pixel and take them from the first conversation all the way to production.

We are at our best with things that are easier to show than to describe. We turn an architectural drawing into a 3D model of an apartment you can walk through in the browser, business logic into a service you can rely on, and a pile of documents into an assistant that answers and cites its sources.

We publish a small version that actually works early on, then keep building it in short steps. That way you always see where the project stands, not just what is planned.

Founder

A senior frontend developer with a track record of designing, architecting and delivering high-performance web applications for SaaS, enterprise and public sector platforms, from compliance platforms and CRM systems to national-scale logistics applications.

He builds with modern frameworks while enforcing rigorous architecture standards and UI consistency, mentors teams, and drives the technical improvements that raise reliability, developer velocity and product quality. He communicates as comfortably with technical teams as with non-technical stakeholders.
