Spencer Nunamaker
AI marketing systems specialist and product builder. Founder of SEMMAP Labs.
I build practical AI systems that help teams move faster with more confidence — content supply chains, campaign workflows, prompt libraries, QA processes, and the internal tools that hold them together. Across 12+ years in marketing and design I've shipped to real customers at every scale: 100+ monthly product campaigns, a business serving 100,000+ people, and an AI content pipeline that turns one deal brief into copy, graphics, listings, and email sends. That same instinct now goes into AI-native software — I'm fluent enough with Claude, GPT, and Gemini to build and ship real tools end to end, and I own the strategy, design, and quality of everything I make. I'm at my best owning a problem end to end and building the system that solves it.
Own the system, end to end.
I take a problem from strategy through shipped result — and I'm fluent enough with AI to build, read, debug, and steer everything it produces.
- I own the whole system — strategy, architecture, UI/UX, information architecture, prompt design, and quality.
- I'm fluent with Claude, GPT, and Gemini — I build with them daily and know where they need a human in the loop.
- I work in Rust, Python, and JavaScript/TypeScript — enough to read, debug, and keep the output honest.
- I ship real products, not prototypes — and keep sharpening them under real use.
What I've built with AI.
MashuPack
A Rust + TypeScript web product, designed and shipped end to end with AI as the implementation partner.
Ishoo
An issue control plane built so AI agents and humans share one canonical model — Dioxus desktop UI plus a deep CLI (plans, ADR decisions, milestones, epics, roadmaps, isolated worktrees).
ROY
A custom shell language that forces AI coding agents into a standardized verb set — typed pipes, structured denial, named refs — to make agent behavior predictable and auditable.
SEMMAP
Semantic codebase mapping that orients AI agents before edits, cutting hallucinated context and improving edit accuracy on large codebases.
OMNI-AST
Cross-language AST normalization — Rust, Python, JS/TS into unified primitives, 97–99% primitive accuracy.
Neti
A polyglot code-governance tool with user-facing KPIs: Responsibility Diffusion, Boundary Sharpness, Smell Density, AI-Rewrite Friction.
Twelve years of shipping to real customers.
