Real systems already in motion

I am starting this section with an internal tool built to control voice agents in Ultravox. The page is now structured to keep adding more examples grouped by project type, so each case can be understood quickly in terms of context, function, and category.

Operational technical infrastructure for web projects

Beyond AI solution development, I also configure and maintain the technical layer that keeps day-to-day operations running. In this case, the setup includes VPS environments on Hetzner and Hostinger, Easypanel installation, and ongoing operation of multiple production services.

Real implementation and operations

The work goes beyond first deployment: it includes maintenance, stability checks, configuration tuning, and operational continuity so the infrastructure can support business growth without technical bottlenecks.

Call manager for Ultravox agents

An internal application designed to centralize operational control over the agents deployed in Ultravox. The goal is to provide a clearer system view, reduce day-to-day friction, and establish a base that can keep expanding with new internal actions, tracking, and workflows.

What this first case introduces

This opening portfolio entry starts with a utility product: a dashboard for managing calls and voice agents. The point here is not to showcase a commercial landing page, but a working interface created to operate a real system more effectively inside an Ultravox-based environment.

Bulk outbound calling app for Ultravox campaigns

Application built to launch large-scale outbound calling campaigns with AI voice agents in Ultravox. It enables campaign setup and execution with operational control, performance tracking, and webhook-driven automations for post-call workflows.

What this solution solves

This tool turns manual campaign activation and follow-up into one workflow: campaign setup, outbound calling, analytics review, and webhook-based automation. It provides a scalable base for growth without losing control, traceability, or execution speed.

Internal product focused on creating operational widgets for AI voice agents and keeping activity under control. It allows teams to build widget configurations, monitor calls, and track usage time from one operational view.

Product snapshot

This second case introduces a build-and-monitor workflow for voice-agent operations. The focus is to combine widget creation and monitoring in one system, making it easier to act quickly based on real usage and call behavior.
