All Projects & Experiments

  • ◇ EXPERIMENT

    AI AGENT · EVALUATION · SAFETY

    Pace Triage Agent

    Insurance enquiry triage and reply drafting with a frozen golden set, human review queue, and 2×2 model/prompt evaluation matrix. Every tested configuration missed the safety bars, producing a defensible no-ship decision.

  • ◇ EXPERIMENT

    AI AGENT · COST & EVALUATION

    RepoCoach

    A source-learning agent used to test agent-loop economics, bidirectional safety gates, and cross-process state. The findings from 638 tests and 22 merged pull requests became reusable engineering guidance.

  • ◇ EXPERIMENT

    RAG · GENERATIVE UI · EVALUATION

    RAG Generative UI Explorer

    Grounded evidence becomes schema-constrained, interactive knowledge cards instead of arbitrary model-generated UI code. Across 60 evaluation questions, dense retrieval reached 63.7% Recall@10 versus 47.6% for BM25.

  • ◇ EXPERIMENT

    AI COST · MEASUREMENT

    Agent Cost Lab

    A measurement lab for real agent bills. The first experiment found that one context compaction took 18–19 turns to pay back, far beyond the 2–4 turns predicted before measurement; fewer tokens did not automatically mean lower cost.

  • ◇ EXPERIMENT

    AI AGENT · DESIGN TO CODE

    Image to Code

    Not "a pixel-perfect page from one screenshot". A Claude Code workflow that turns AI-generated design sources into reusable, validated frontend packages — preserving real assets and design language, materialising component files with props, variants, tokens, and manifests instead of flattening everything into one page component. Observable intermediate artifacts, deterministic contracts, cheap validation, and human review only where visual judgment is still necessary.

  • ◇ EXPERIMENT

    AI DESIGN · RESEARCH

    Design Reasoning Lab

    Not "what can this tool generate" but "how does it think". Reproducible behavioural experiments reverse-engineering how AI-native design tools reason — what they ask the human for, which decisions they delegate, and how output modes relate. The current case study is Claude Design with v0 as contrast; claims are kept at four distinct epistemic levels — fact, interpretation, hypothesis, conclusion — so observation is never merged into explanation.

  • Brooch Shop

    ● LIVE

    AI AGENT · E-COMMERCE

    Brooch Shop

    Where filters fall short, agents begin. An AI shopping agent built with Claude API and tool calling — demonstrating how natural-language intent understanding replaces multi-level filter UX.

  • Prompt Shop

    ● LIVE

    CHECKOUT · STRIPE

    Prompt Shop

    End-to-end e-commerce checkout playground with Stripe integration — covering the full flow from product listing to payment confirmation.

  • Human vs AI Judge

    AI · GAME · E-COMMERCE

    Human vs AI Judge

    When AI has already decided, who presses confirm? Compete with AI on intent classification of real e-commerce support tickets — compare human, Claude, and GPT judgments in real time.

  • Readable & Shareable

    ● LIVE

    CLAUDE CODE · SKILL · VISUALIZATION

    Readable & Shareable

    You wrote a great article — most people won't click the link. A Claude Code `/viz` skill that detects article structure and generates mind maps, interactive HTML, and shareable image cards — each output links back to the source so every audience finds their entry point.

  • Particle Flow Generator

    ● LIVE

    CANVAS · SIMULATION

    Particle Flow Generator

    Stacking time into space. Simulating the spatial residue of user trajectories with particle flows — Canvas 2D real-time rendering, BFS flow-field pathfinding, live parameter tuning and GIF export.

  • SSB Website

    ● LIVE

    DESIGN ENGINEERING · FRAMER MOTION

    SSB Website

    A design engineering exercise — four-page B2B marketing site built from scratch. Features a custom physics bounce hook with velocity vectors and wall-reflection, responsive layout, and Framer Motion animations. Lighthouse: Performance 91 / Accessibility 96 / SEO 100.

  • Design Token Signals

    ◇ EXPERIMENT

    DESIGN SYSTEM · EXPERIMENT

    Design Token Signals

    Design tokens don't just store values — they carry meaning. An experimental tool for analyzing the visual signals that token combinations transmit: mapping the semantics of color, radius, and weight to surface conflicts before a component is built.

  • EaseBuy

    ◆ HACKATHON ★ TOP 10

    UX DESIGN · E-COMMERCE · MOBILE

    EaseBuy

    Top 10 in UXcel × UX Pilot Design Competition. A minimalist mobile e-commerce app covering the full shopping journey across 11 screens — generous whitespace, card-based IA, transparent checkout. Full flow from wireframe to hi-fi with AI assistance.

  • Spec-Driven Scenario Updater

    ◆ HACKATHON

    AI AGENT · GITLAB HACKATHON

    Spec-Driven Scenario Updater

    GitLab AI Hackathon submission. Targeting the "spec gap" — the distortion that accumulates as business logic is translated across product, design, and engineering. A single spec source drives AI to auto-generate code, tests, and docs.
