Frequently Asked Questions
I've worked across AI and research products, enterprise SaaS, productivity tools, consumer apps, and e-commerce.
Both. I can jump into your existing team and work hands-on with your designers and engineers, or operate independently and own design end-to-end.
Yes. I've built production apps in React, React Native, and Node.js, so I can handle prototyping, technical validation, or fill development gaps when needed.
It depends on the engagement. For ongoing work, I typically use a day rate. For longer defined projects, a flat fixed fee so there are no surprises.
You get senior-level work without the overhead. With an agency, you're paying for account managers, junior designers padding timelines, and internal processes. With me, you work directly with the person doing the work; someone with 12+ years of experience who can both design and build if needed. Faster decisions and tighter communication.
Yes, from early stage startups and scale-ups to global enterprises. How we work together depends on what you need, whether that's end-to-end product design, design support, or strategic consulting.
