User interviews, competitive audits, and heuristic analysis to uncover real problems before designing solutions.
Design systems, component libraries, and tokens that scale — keeping product and brand consistent across every surface.
Pixel-precise, interaction-rich Figma deliverables and Framer prototypes that dev teams can ship without guesswork.
Usability testing, A/B experiments, and analytics review — closing the loop between design decisions and outcomes.
Facilitated 40+ design sprints and workshops with stakeholders, engineers, and PMs across timezones.
Framer and Webflow builds that go from design file to live product — faster iteration, zero dev dependency.
Fluent in the new stack — using AI tools to move from idea to shipped product faster, without sacrificing design quality.
Design is only as good as the decisions it enables.
I'm Alex Kostakis, a Senior Product Designer based in Athens, Greece. For the past 6 years I've been helping startups and scale-ups build digital products that people actually want to use.
My work sits at the intersection of UX strategy, interface craft, and business outcomes. I care deeply about accessibility, system consistency, and the gap between design files and shipped reality.
Currently open to senior IC roles and consulting engagements — product redesigns, design system audits, and zero-to-one builds.
