about
A product designer for the complicated parts.
I'm Sergiy Paramonenko, a product designer based in Odesa, Ukraine, working with remote teams. I focus on B2B SaaS, fintech, data-heavy products, and the design systems that help them grow.

I help teams turn complicated workflows into interfaces people can understand, use, and build on.
My work moves between product structure and interface detail: defining a journey, deciding what a screen should prioritise, handling the states around an action, and documenting patterns for the people who build the product. I like projects where the difficult part is making complex information useful without pretending that it is simple.
I collaborate closely with product managers, engineers, and stakeholders. I use prototypes to make trade-offs visible, ask questions early, and leave a system the team can keep using after a screen is delivered.
philosophy
Clarity is a
team decision.
Start with the task
A screen makes sense when the team understands who uses it, what they need to decide, and what happens next.
Respect real complexity
Financial data, automation, and operations have important detail. I organise it so people can find the right depth at the right moment.
Make decisions reusable
A design system captures how the product behaves, not only how it looks. Components, states, and usage rules keep the experience coherent as it grows.
Background
Experience across products and stages.
I've worked on established products, early-stage ideas, and the systems that connect many teams and screens. Here is the relevant path behind the work.
