Capabilities

From product scope to store release

Shape the MVP

I clarify the user, critical flow, scope, and release target before engineering starts.

Build the product

I handle Flutter and mobile engineering, backend work, integrations, and the data the product needs.

Prove it works

I test on devices, work through edge cases, run QA, and prepare the release with fewer unknowns.

Ship and learn

I deploy to the stores, prepare analytics, and use the first release to make the next build decision.

Supporting work

Web work, when the product needs it

About

I bring founder decisions into the build.

I am Hrvoje Bencik, a founder who has shipped my own products and an engineering lead for client products. I connect commercial decisions with the practical work of getting a product built, tested, and released.
