Founder and CEO of MTN Media Group, building MTN AI and the infrastructure behind modern digital products, hosting, and IT services made in Germany.
- Building MTN AI: a unified platform for chat and image models with transparent privacy tiers and usage-based token billing.
- Running infrastructure for hosting, IT solutions, web products, automation, and internal tools at MTN Media Group.
- Studying computer science at FH Aachen University of Applied Sciences.
- Working mostly in private company repositories, so this profile is only the public slice of my engineering work.
MTN Media Group started in March 2020 and provides IT services made in Germany. The company works across AI products, hosting, IT solutions, web design, and event services.
What I usually care about:
- Reliable backend systems and infrastructure that can be operated in production.
- Clear privacy and cost controls, especially around AI and cloud usage.
- Practical automation for support, billing, monitoring, deployment, and internal workflows.
- Interfaces that are simple enough for customers and robust enough for operations.

- Languages: Go, TypeScript, SQL, Bash/Shell; working knowledge of C++ and Python.
- Backend: REST APIs, Gin-based Go services, authentication, user management, billing, invoicing, payment integrations, admin panels, and internal tools.
- Frontend: Vue for product interfaces, with plain HTML/CSS and UI/UX work where the project needs it.
- Infrastructure: Linux servers, especially Arch Linux and Ubuntu, Docker Compose, Cloudflare, Ubiquiti UniFi, Hetzner, Proxmox, Plesk, game server hosting, networking, firewalls, and VPNs.
- Data and operations: PostgreSQL, Redis, SQLite, S3-compatible object storage, backups, uptime monitoring, Sentry, logging, observability, GitHub Actions, and CI/CD.
- AI and automation: OpenAI API, Anthropic/Claude, Ollama/local models, multi-provider AI platforms, token/cost tracking, MCP integrations, and AI-assisted engineering workflows.
- Tools: VS Code, JetBrains IDEs, Cursor, Codex CLI, Claude Code, OpenCode, and Postman/API testing.
- Also familiar with Kubernetes, Nginx, Traefik, AWS, Google Cloud, MySQL/MariaDB, Grafana, Prometheus, and Open WebUI.
Most production work happens in private MTN Media Group repositories, so public GitHub cards only show part of the picture.

Local token usage from my AI-assisted engineering workflow across Codex CLI, Claude Code, and OpenCode. I use these tools for planning, implementation support, review, and documentation, while keeping architecture, testing, security, and production ownership with me. |
