Dustin Schultz

Senior Software Engineer — UI Systems & Agentic Infrastructure

I build the interfaces and infrastructure that make complex systems usable — from Fortune 200 capital allocation platforms to agentic workflow engines with LLM integration. 15 years in UI, currently deep in the agent layer.

Featured Projects

🤖 Groundswell

Hierarchical agentic workflow engine

📋 Formality

Declarative form logic as configuration

What it is: A TypeScript workflow orchestration engine with LLM agent integration, hierarchical task composition, and full observability.

What I built:

Workflow class with parent-child hierarchy, lifecycle events, and state serialization
Agent class wrapping Anthropic SDK with tool invocation cycles and session management
Prompt system with Zod-validated responses and typed AgentResponse<T>
@Step / @Task / @ObservedState decorators for declarative workflow definition
Deterministic SHA-256 LLM response caching with hit/miss metrics
Reflection system for multi-level error recovery and automatic retry
6 introspection tools for agents to inspect their own position in the workflow tree
React visual debugger (WorkflowTreeDebugger) with tree rendering, split-pane inspection, and event replay
Multi-provider architecture (Anthropic, pluggable) with session hooks

npm install groundswell

import { createWorkflow, createAgent, createPrompt } from "groundswell";
import { z } from "zod";

const agent = createAgent({ name: "AnalysisAgent" });

const prompt = createPrompt({
  user: "Analyze this code",
  responseFormat: z.object({
    bugs: z.array(z.string()),
    severity: z.enum(["low", "medium", "high"]),
  }),
});

const response = await agent.prompt(prompt);
// response.data.bugs — fully typed, Zod-validated

What it is: A multi-package form logic library that replaces scattered useEffect hooks with a single declarative config object. Built on React Hook Form.

What I built:

@formality-ui/core — framework-agnostic logic engine (zero deps)
@formality-ui/react — React bindings with FormalityProvider, Form, Field, FieldGroup
Expression parser for string-based conditions ("quantity * unitPrice", "age >= 25 && hasLicense")
Condition engine controlling visibility, disabled state, computed values, and cascading dependencies
Framework-agnostic architecture with planned Vue and Svelte adapters

npm install @formality-ui/react react-hook-form

// Before: useEffect spaghetti
useEffect(() => {
  setTotalPrice((quantity ?? 0) * (unitPrice ?? 0));
}, [quantity, unitPrice]);

// After: one config object
const config = {
  totalPrice: {
    type: "number",
    conditions: [
      {
        selectWhen: "quantity && unitPrice",
        selectSet: "quantity * unitPrice",
      },
    ],
    disabled: true,
  },
};

⌨️ QMKonnect

Cross-platform Rust desktop daemon that watches the active window and streams it to your QMK keyboard over Raw HID, so the board can switch layers or run commands per app. Windows, macOS, and Linux (Arch/Hyprland), with zero-config auto-discovery and host-side rules.toml rules that hot-reload without reflashing firmware.

cargo build --release && ./qmkonnect
# auto-discovers any QMK board via Raw HID (usage page 0xFF60 / 0x61)

# rules.toml — switch layers per app; hot-reloads on the next window change
# (no firmware rebuild, stacks on top of your board's DEFINE_SERIAL_* rules)

🔧 Jin

32-command Rust CLI for layered developer configuration management. 9-level merge precedence system built on Git internals (git2 crate). Manages tool-specific config (.vscode/, .claude/, .cursor/) without polluting the main repository.

cargo install jin
jin init && jin mode create dev && jin apply

🚀 RESTstop

Generates a complete REST API from a PostgreSQL schema — controllers, routes, models, CRUD endpoints, smart faker seeding, migration splitting, and OpenAPI spec generation. Docker-first.

docker compose up -d
./yii setup/generate-all --seed=100
# Full API running with 100 records per table
