I turn complex product decisions into direction teams can build from.

I lead product strategy and design for enterprise ads and AI-native products, where the roadmap is full and the hard part is choosing. I start with the strategy and how the backend works, then design and prototype against the real system, so the work is technically grounded and informs product direction. With a team, I set the bar and coach designers into owning what they ship.

Work

Private case
Bayesian Leaf · Applied AI platform

Strategy to launch for a natural-language geospatial AI platform.

Six weeks of product strategy, then design through a public launch. The search asks before it runs, confidence shows as tiers traced to sources, and engineering built from working prototypes instead of pictures.

Value preferences for automated bidding.

Lets advertisers say what is worth more, and bidding leans toward it. I set the direction and coached the designer who shipped it. Bid Multiplier shipped first.

One navigation for Pinterest’s ads tools.

Menus organized by team became columns organized by advertiser jobs. I led it across eight organizations. 25% fewer navigation opens at the same page visits.

A platform blueprint for Opendoor operations.

Thirty-five operator sessions shaped a twelve-capability blueprint for internal tools. I co-led the research and co-authored the blueprint, then took ticketing to version one.

A recommendation framework for Meta Ads Manager.

One framework so any team could ship mid-flight campaign advice, plus feedback the ranking model could read. I led both, as design lead for a team of three. Snooze, mute and dismiss shipped in 2021.

What it’s like to work with me

“From an engineering perspective, we pivoted to a more integrated UI and backend design as a direct result of Hew calling out the need for better transparency, the need for easy evidence inspection, and making complexity accessible behind a simple UI.”
Head of ML Engineering, Applied AI Platform Bayesian Leaf client
“Influencing roadmaps with the optimal set up framework, it's difficult not to feel the impact you've had. You've become a leader that our cross-functional partners want in the room.”
Design Manager, Pinterest Internal recognition
“I greatly appreciated that he stepped up to lead the team while [our design manager] was on leave, this ensured we maintained momentum during planning and also delivered quick turnaround work for executive reviews (P+ adoption).”
Director, Monetization Design, Pinterest Internal review
“Ultimately I think Hew’s biggest strength is that he dives deep into problems and makes sure that any recommendation he’s proposing is well reasoned and takes into consideration every possible known factor.”
Director, Monetization Engineering, Pinterest Internal review
“In my experience he always starts his investigation from the needs of the customer. This first principles approach not only led to intuitive designs, but also uncovered opportunities to improve the experience within Ads Manager at large.”
Director, ML Product Management, Pinterest Internal review
“Formally titled a designer, but constantly acting as a little bit of everything: a strategic researcher, a technologist, a product manager.”
Data Scientist, Pinterest Internal review
“Hew proactively proposed solutions like incorporating bid modifiers to enable user control, and then demonstrated the technical feasibility.”
Senior Product Designer, Pinterest Internal review
“Always 3 steps ahead, Hew is a true mastermind and strategic connector who innately identifies gaps, opportunities and patterns across a product.”
Product Designer, Pinterest LinkedIn

Practice & Ventures

Bayesian Leaf

My product and design practice for companies building with AI. Evaluation frameworks, and the standards that decide when a model-driven capability is ready for customers, on an operating layer I built that takes a structured brief to a working prototype and an engineering-ready data contract. As fractional Head of Design for an applied AI platform, I reframed the core interaction model, specified the analytics events the product was missing, and built working prototypes against the real codebase.

Human Commons

My product studio. Most products build a world and ask you to move into it. These enter the one you already live in. Two products so far, both built solo, and both start from a person and a place.

Earlier
Split

A payments startup for diners and restaurants. I co-founded it and ran its product. TAG FinTech Innovation Award.

MOWGLI

A music technology startup. I directed a team of six through Songster, a gamified audio workstation and an SXSW Interactive Accelerator finalist.

About

I'm a child of journalists, so I grew up in and out of newsrooms. A newsroom does one thing. It takes something complicated and makes it usable to somebody who has to act on it. I have done that work ever since, on the ad platforms at Meta and Pinterest, the operations behind Opendoor and mobile news at CNN. Today I manage a product design team at Meltwater, back in media. The same instinct runs through Bayesian Leaf, where I apply it inside other companies, and Human Commons, where I build the products I think should exist.

I manage a principal and senior designers at Meltwater. At Pinterest I managed six designers as interim design manager and cut delivery time 30% by consolidating three overlapping workstreams and resetting how the teams worked together. As design lead, without a reporting line, I led five designers and two researchers on the Ads Manager platform at Pinterest and six designers on Ads Targeting at Meta.

I think in systems, in the frameworks and governance that orchestrate the work. Frameworks other teams chose to build against, at Meta and again at Pinterest. The Pinterest framework began before the work had a mandate. A governance process that continued deciding what shipped after I left. A leveling framework a growing design team will hire against. A designer who now leads a product line of their own. The design that sits on top is craft. I write code because a picture of a thing will not tell you whether it works.
