Denys Sergushkin

Design Engineer & Principal Product Designer — agentic UX for B2B and ERP

14 years designing complex systems: ERP, AI-powered SaaS, enterprise workflows. When a design question is about latency, autonomy or trust, a static mock cannot answer it — so I build the answer instead.


Building in the open

Project The question it answers
Agentic UX Lab When you're spending a finite allowance, what number do you actually need to see? Live demo →
Workflow canvas What does an interface look like when a system is honest about not knowing? Live demo →
Knowledge Atlas What if you could see where an AI was guessing, and overrule it? Live demo →

What I'm focused on

  • Agentic UX — interfaces where AI acts and humans supervise
  • AI workflow builders for B2B SaaS and ERP automation
  • Prototyping in code — settling interaction questions before they reach Figma

Career highlights

  • Xentral — Led UX for AI-powered workflow builder. Agentic features now a core part of sales demos
