Selected Projects

Case studies connected to commercial services

These project pages now act as proof pages for the service offering instead of standing alone as disconnected portfolio items.

Case study

Carv

Carv is an AI recruitment platform built around meeting capture, transcription, summaries, prompts, and recruiter workflows. Tomas led the initial rewrite from React to Flutter with Firebase on Google Cloud, helping define the technical architecture early enough that the product could move quickly without collapsing under its own complexity.

ElevenLabs

R-DEV collaborated with ElevenLabs on a Flutter application layered over the ElevenLabs API. The work focused on maintainable architecture, responsive API communication, and the sort of audio pipeline details that usually break cross-platform apps if they are handled casually.

li-nk.me

li-nk.me is a SaaS platform built to make Universal Links and App Links practical for growth teams. Instead of leaving teams to manage Apple App Site Association files, Android Asset Links, SSL, redirects, attribution, and fallback pages themselves, the platform handles that infrastructure as a product.
