Levi

Senior iOS Developer · AI Builder · Co-creator of RoleCall

8+ years building iOS apps, now deep in AI. Strong background in math and computer science — I think in architectures and abstractions, not just implementations. I love bringing organic order into chaos: non-disruptive solutions, automation, and making hard concepts easy to understand. Currently based in Paphos, Cyprus.

Experience

Founding Engineer

RoleCall Studios

2025 — Present

Co-built RoleCall alongside Chi and Nemo — a premium AI roleplay platform serving a growing community of creative storytellers. Designed the multi-agent architecture: a DM (story director) that plans narratives and manages a shadow world, a TV sidecar for autonomous lorebook management, and a narrator engine with tool-calling loops. Built the inference router supporting 25+ providers with E2E-encrypted BYOK, the immersion engine (27 reactive game state trackers driven by AI directives), and the Compendium typed knowledge system.
