Product engineer. Full-stack. AI-native.

I design and ship products across UX, frontend, backend, and AI workflows — from experimentation-heavy product teams to AI-native systems with real integrations, operational visibility, and controllable execution.

What I'm unusually good at

I work best where product, engineering, and practical AI meet.

End-to-end product ownership

I work across UX, frontend, backend, integrations, and operations — and I care about what actually ships, not just what gets discussed.

Applied AI that survives reality

I build around models with workflows, tools, evaluation, retries, and human control instead of pretending a prompt is a product.

Product sense + experimentation

I come from experimentation-heavy teams and care whether users actually get value, not whether a feature only sounds impressive in a demo.

Systems with real consequences

I gravitate toward systems where things actually happen: background jobs, fulfillment pipelines, API integrations, automations, and business workflows with operational weight.

Design literacy

I started in product design, which is probably why I still care so much about how technical systems feel to use — not just whether they work.

Fast in unfamiliar territory

I’m comfortable navigating new domains, identifying what matters quickly, and building toward something real before conditions are perfect.

Selected work

A few projects that best show how I think, build, and ship.

Upscale Print

A live product that turns user photos into gallery-quality prints through an AI-enabled workflow spanning enhancement, checkout, fulfillment, and customer-facing UX.

Selected experience

A few teams and environments that shaped how I build.

Booking.com5 yrs

Built internal ML tooling and experimentation interfaces that helped product and data teams work with models in a high-scale environment.

Cohabs4 yrs

Owned product work across web and mobile, including member-facing flows, backend services, and internal tools for operations and support.

HiCoach1 yr

Founding product engineer from concept to launch, spanning product direction, UX, backend API, and mobile/web implementation.

How I work

—I like building products, not just shipping tickets.
—I prefer practical systems over clever abstractions.
—I care about observability and control when AI is involved.
—I think good UX is part of engineering quality.
—I learn fastest by shipping and iterating.

A few quick answers

What kinds of roles are you looking for?

Remote product engineering roles where AI is part of the product or workflow, and where I can own meaningful work end to end.

Are you open to on-site or hybrid?

I'm looking for remote positions only. I've worked effectively in distributed teams across time zones and have a strong async communication style.

Are you more frontend or backend?

Both, realistically. My background started more frontend/product-side, but a lot of my recent work is backend workflows, integrations, and AI system design.

How much of your recent AI work is production vs experimental?

Upscale Print is live. The marketing agent system is an active applied AI project focused on making agentic workflows operationally useful, observable, and controllable.

If you’re building products where AI needs to be useful, reliable, and grounded in real workflows, I’d love to talk.

Let’s build something useful together
