Two decades of shipping production systems, constantly evolving the stack. Investment banking, commodities trading, data platforms, B2B commerce, media, consumer services — all shipped at scale.

A bad deploy is an incident, not a bug.

A four-year engagement leading a B2B commerce platform's build and cloud migration. 300,000 products in production on AWS. Architecture, DevOps, and the remote-team shipping culture that got it out the door. End-to-end ownership. This is the shape of work Avant Media is built for.

Days, not sprints.

Spec-driven development, AI-assisted code generation, release automation — that is how. MushRoom is our proof: a multi-tenant property-management platform, AI-integrated, deploying every day.

What Avant Media does

AI integration for production systems

Language models into legacy codebases, without breaking them. Most AI work is greenfield. Avant Media does the harder problem: real users, real data, real regulatory constraints.

Concretely: MushRoom ships an OAuth-authenticated MCP server that lets Claude and other AI clients read and update real bookings, finances, and tax data through property-scoped tools — an LLM wired into a live, multi-tenant product, deployed every day. Not a demo.

Senior engineering on call

Architecture, code review, hiring, deploy practice — for founders and small teams building something that has to hold up. An adult in the room when the stakes get real.

Senior engineering applied to client work since 2013. MushRoom as a working example of what good looks like.

MushRoom — property management software

Avant Media's own product. Mobile-first property management for short-term lets, built around how the work actually runs — no SaaS bloat, no desktop-only dashboards.

In production: NTAK reporting for Hungary, Airbnb calendar sync, multi-tenant from day one, MCP-accessible to Claude and other AI clients, automated invoicing, real-time P&L — deployed every day.
