I'm a senior UX & product designer specializing in enterprise platforms that help people communicate, make better decisions, and work smarter at scale.
Topics and problems I'm actively thinking about.
Focused on the interaction patterns, decision points, and trust signals that make agentic experiences feel controllable. Designing for AI that acts, not just responds.
How tone, guardrails and error states set the right expectations and shape the experience when interacting with an AI agent.
AI-powered features make work more efficient without becoming the destination. Embedding them directly into the workflow so they're contextual and available at the point of need.
I joined PubMatic in Spring 2025 to help evolve Activate, the company's buy-side advertising platform. Much of my time has been spent understanding how traders and media buyers actually work, then translating those insights into better workflows, more intuitive features, and a more cohesive product experience.
More recently, I've been focused on introducing agentic AI capabilities into the platform. Rather than treating AI as a standalone feature, the goal has been to integrate it directly into existing workflows where it can reduce friction, accelerate common tasks, and provide meaningful assistance at the right moments.
Ironlight was where I really got to own a product from scratch. I led design on a tokenized asset exchange — which meant figuring out how to make something genuinely novel feel familiar enough to actually use. Heavy on systems work, and a lot of time spent making complex financial data legible without dumbing it down.
This role came out of Symphony acquiring Cloud9, so I walked in with context most designers wouldn't have had. I helped stitch two products together — integrating Cloud9's voice features into Symphony's messaging platform — while also running research and redesigning parts of the admin experience that had been neglected for a while.
Cloud9 was where I made the jump from implementation and client services into design full-time. Having spent years on the client side, I already understood how traders actually used the product — which made me a lot more useful in research and a lot harder to fool in design reviews. I came up through the company, so I had context most designers walking in off the street wouldn't have.
Structure without rigidity. Stages overlap, order shifts, and iteration never stops.
Everything begins with research. Whether it's user interviews, feedback sessions or workflow analysis, I put the human first to identify the real problem being solved.
Workflows, wireframes and prototypes all take shape. From low to high fidelity, this is where the creativity happens.
Before handoff, prototypes are tested with real users. What's learned either validates the work or sends me back to the drawing board.
Engineering is looped in and designs are handed off. Once live, I'm looking at KPIs and feature adoption to see if it's a success.
I'm Greg, a UX & Product Designer based in the New York Metro Area, where I've lived for over 14 years.
I think of myself as a "full-stack" designer, someone who's comfortable operating across the full spectrum of product design. From early discovery and research, through the iterative design process, all the way to developer handoff, I care as much about the who and why as I do about how it looks and feels.
I specialize in complex, data-heavy enterprise applications built for demanding users with highly specific workflows. Regardless of the problem, my approach always starts with the user. Understanding who they are, what they do, and why is at the core of everything I design.
Outside of my professional life, the title I'm most proud of is "dad." It's by far the most fulfilling and rewarding thing I've ever taken on. Free time looks a lot different these days, but when I do find a moment you can catch me at the gym, out running with the dog, or during winter months chasing fresh powder somewhere out west.
Other hobbies of mine include gaming, being the commissioner of a very competitive fantasy football league, and indulging in some of the best steaks that NYC has to offer.
I'm open to senior product design roles, consulting engagements, and conversations about hard problems.
