Production AI integration, cloud migrations, and senior engineering for founders and small teams.
You work directly with the senior engineer who writes the code.
Critical work requires critical thinking.
Two decades of production systems: investment banking, commodities trading, data platforms, B2B commerce, media, consumer services. Environments where a failed release costs real money. The standard comes from there.
A four-year embedded engagement led the build and AWS migration of a 300,000-product B2B commerce platform. Architecture, DevOps, and the shipping culture that got it out the door. This is the shape of work Avant Media is built for.
Changes are verified before they ship. That is where the speed comes from — days, not sprints.
Twenty years spans several platform shifts: the browser became the platform, the racks became the cloud, deploys became automated, language models arrived. Each shipped under the same standard. AI is the current shift.
Language models into legacy codebases, without breaking them: real users, real data, real regulatory constraints.
MushRoom ships an OAuth-authenticated MCP server: Claude and other AI clients read and update live bookings, finances, and tax data through property-scoped tools — an LLM wired into a multi-tenant product, deployed every day.
Architecture, code review, hiring guidance, deploy practice. The senior in the room when a small team is building something that has to hold up and there is nobody else to push back.
SpecForge is the studio's developer tool: MIT-licensed, mutation-tested, the full source public. The standard is inspectable, not just described.
Multi-tenant systems on AWS. Replatforming. Cloud migration. Architecture and DevOps owned throughout, including the deploy culture that makes releases boring.
MushRoom runs multi-tenant on AWS. The four-year engagement above moved a 300,000-product B2B commerce platform onto AWS and ran it there.
Senior engineering plus current AI tooling, applied across the whole of a build — the approach behind the work in the portfolio.
