Practice
Jennifer Hull, Senior Product Designer with technical execution depth. I build multi-tenant UI architecture, token systems, and agentic workflows that survive contact with reality. Remote contract IC · SA ↔ EMEA timezone parity · async-first.
// 01 Core Practice
Systems
Architectural Governance
I treat design systems as immutable infrastructure: logic-driven libraries, advanced variables, and semantic tokens that stay maintainable under Day 1 pressure.
Engineering
Frontend Execution
Drop-in tooling, local overlays, and production interfaces in React 19, TypeScript, Next.js, and Tailwind CSS v4. Design intent that survives the handoff.
AI / ML
Agentic Design Ops
Frameworks that move AI from static chatbots to steerable partners: human-in-the-loop control, deterministic routing, and Zod-shaped agent contracts.
// 02 Engagement Models
Remote, async-first contract IC. Written briefs, documented decisions, deep execution, not sync-heavy performative meetings. I am open to flexible structures based on the problem space.
FRACTIONAL
Retainer
Ongoing, embedded partnership (e.g. 2-3 days/week). Ideal for teams needing senior architectural oversight or continuous design engineering without a full-time headcount.
FIXED_SCOPE
Project
Execution for discrete challenges. From zero-to-one product design to complex design system migrations and multi-tenant logic layers.
STRATEGIC
Advisory
Guidance for existing teams. Codebase reviews, token architecture audits, and agentic workflow viability assessments.
// 03 Named Offer
[EXECUTION_SPRINT]
Agent Demo Sprint
> analyze_blocker --target="AI Features"
Error: Static mocks cannot validate LLM routing. Production builds carry high risk without technical validation.
> execute_sprint --mode="Agent Demo"
Success: One polished, deployed agent workflow delivered. Technical viability proven prior to scale.
// Deliverables: one workflow · staging URL · repo + Loom handoff
// 04 Shipped Infrastructure
The Mothership
Orchestration console that encodes design systems into machine-readable instructions.
DX Spatial Grid
Open-source harness to inspect layout nodes and calibrate spatial tokens in the browser.
