Services

Three ways I work with clients — from full product builds to focused AI integration.

AI Product Development

You have a product idea, a set of mockups, maybe a no-code prototype that's hitting its ceiling. You need an engineer who can own the whole thing — not just write code, but make decisions about architecture, data, and what to build first.

I take products from concept to production system. That includes the parts nobody wants to talk about early: auth, data modeling, deployment pipelines, and the engineering practices that keep things from falling apart at scale.

What this looks like

  • —You have a product concept or early prototype — I scope, architect, and build it
  • —You have a no-code platform that's outgrown itself — I migrate it to a real stack
  • —You need a sole engineer who can own frontend, backend, and infrastructure — that's the job

AI Integration

Your team is using LLMs but it's duct tape. Prompts live in Slack threads. Nobody knows which version of the system prompt is in production. The output is inconsistent and nobody's sure why.

I build structured AI workflows — multi-agent orchestration, prompt versioning, context-budgeted systems — and I introduce the engineering methodology to keep them running. Not experiments. Operational tooling.

What this looks like

  • —Prompt systems that are version-controlled and testable
  • —Agent architectures with evaluation protocols and contracts
  • —Engineering methodology your team can run without me

Audio & Text Tools

Custom AI-powered tools for people who make things. Musicians, writers, artists, content creators — if your work involves audio or text and you need technology that understands the material, not just processes it, this is the work I care about most.

What this looks like

  • —AI analysis tools grounded in real audio/text understanding
  • —Creative workflow tools that augment the process, not replace it
  • —Commissioned builds for specific creative problems
