Expertise
Product Engineering
Full-stack builds with Next.js, TypeScript, and PostgreSQL — from first schema to production deploy, including billing, auth, and the unglamorous parts that make software dependable.
AI Systems & Workflows
LLM integrations that earn their keep: voice interfaces, agents, and workflow automation designed around what your team actually does all day.
Commerce & Payments
Storefronts, subscriptions, and payment rails — card or crypto — with the checkout speed and conversion discipline of a decade spent optimizing them.
Product Strategy
A senior engineer in the room for scoping, technical due diligence, or getting a stalled build unstuck — short engagements, straight answers.
