Product & interface
Turn fuzzy goals into flows people understand on the first pass.
- Product discovery and scope framing
- Interaction design and design systems
- Accessible, responsive UI implementation
- Design-engineering handoff without drift
Full-stack delivery
Production software with architecture that stays boring to maintain.
- React, TypeScript, and TanStack Start / Router
- API design, data modeling, and server functions
- Cloudflare Workers and edge-friendly deploys
- Auth, caching, and performance budgets
AI-powered products
Useful AI with clear trust boundaries, not demoware on top.
- LLM integrations, tools, and retrieval
- Agent workflows with human-in-the-loop guardrails
- Evaluation, prompting, and cost/latency tradeoffs
- Prototypes that graduate to production patterns
