AI-native full stack. Deep frontend expertise.
19 years shipping production software — from enterprise applications serving 1,000+ locations to zero-to-one products. I turn ambiguous problems into software people can actually use.

Engineering systems that improve how teams ship.
Worked across an engineering organization of 20+ people, improving delivery practices and making quality, testing and repeatability part of the system rather than an afterthought.

Products from idea through working software.
Since 2021, shipped an App Store iOS product, a Vercel-hosted service business and an autonomous trading system across web, mobile and backend surfaces.
How I build with AI
AI is leverage, not authorship theater. I use it to increase iteration speed while retaining responsibility for architecture, correctness, accessibility and what ships.
Understand
Users, constraints, success criteria and system boundaries.
Accelerate
Claude Code, ChatGPT and Copilot for exploration, scaffolding and iteration.
Engineer
Own architecture, implementation choices, integration and debugging.
Verify
Test behavior, accessibility, edge cases and production assumptions.
Ship
Deploy, observe, communicate and iterate against real outcomes.
Proof of execution
From brief to working product.
A representative rapid product challenge: unfamiliar domain, compressed timeline and a mixed technical/executive audience.
- Translated an ambiguous brief into an interactive product experience.
- Used AI-assisted development to accelerate research, scaffolding and iteration.
- Added accessibility and production-minded refinement rather than stopping at generated output.
- Presented the product, architecture and tradeoffs clearly to a broad stakeholder audience.
- Disclosed AI use directly and retained human responsibility for the finished work.

Where I fit
My strongest roles combine product ownership, frontend depth, full-stack execution and the judgment to use modern AI tooling without lowering the engineering bar.
Staff / Senior Product Engineer
End-to-end product ownership, ambiguous problems, customer-facing systems and technical leadership.
Staff Frontend Engineer
Complex React/TypeScript applications, architecture, accessibility and product-quality interfaces.
AI Product Engineer
Rapid AI-assisted iteration paired with experienced engineering judgment and production responsibility.
Senior Full-Stack Engineer
React/Next.js surfaces backed by Python/FastAPI services, data stores and deployed products.
