Profile
STAYU KASABOV
My approach to product design is built on a career spent at the intersection of business strategy and technical implementation. Having led my own agency for 16 years, (Nuvizus Communications), I developed a deep accountability for business outcomes, moving products from initial SWOT analysis, Product Design and PRD definition through to final deployment.
Over the past five years, I've pivoted that experience into the startup space, specializing in the UX consulting and contribution to robust Design Systems. My focus is on bridging the gap between design and engineering with prototyping and creating systems that aren't just visually polished, but technically buildable and scalable.
I have a track record of delivering results for news agencies, entertainment broadcasting, and enterprise software. My work is about translating complex problems into high-impact, positive UX.
Currently, I'm looking for a role where I can contribute to established pipelines and drive a high-standard design production lifecycle.
Value
VALUE PROPOSITION
WHAT I BRING
Lead the transition from initial research to final execution. Define the logic behind the interface through user flows, heuristics, and technical vetting. Ensure the product is built on a foundation that is both user-centric, business aligned and technically viable.
Focus on the "how" as much as the "what". My expertise lies in creating seamless handoffs through precise documentation and a deep understanding of implementation constraints. Ensure that the design intent remains intact throughout the development cycle.
I use prototyping as a tool for validation, with systemic approach to solve complex problems. Help for the teams to move from MVP to a scalable product without losing functional integrity.
Maintain a critical approach to new technology, adopting new workflows and tools only when they enhance production speed or product quality.
