Alen Požun

Remote, hourly contract or part-time work (20–40 h/week) in AI training and evaluation, Croatian–English language tasks, Android development, or technical support. Self-taught developer building offline-first Android apps with local AI; 2 years as an IT technician. Can start immediately. I built and maintain Meridian Family, a suite of five interconnected Android apps designed to run AI on-device. Meridian Core provides an ADB-based elevation service that works over local loopback, while Meridian Chat serves a local Qwen3.5-4B vision model through llama-server in Termux. For Meridian Chat, I created a multi-agent pipeline that uses a 0.6B scout model for fast extraction and a larger model for heavier reasoning, with gating and escalation. The apps share a signing key and settings, and their offline-first design keeps the focus on privacy and zero-cloud use. I also tested Vulkan GPU-only inference on Exynos 2600 / Xclipse 960 and built a root-free ADB monitor to track device performance and thermals. Before this work, I was an IT Technician at Futura Informatička Tehnologija d.o.o., building PCs, servers and mining rigs and repairing computers.
