Serhii Tsyhychko

15+ years across SaaS, enterprise, marketplace, B2B and B2C environments.

Consistent focus: structuring complex products where multiple roles, workflows, and decision layers require clear definition.

Specializing in product architecture and requirements engineering. I transform fragmented stakeholder input into structured, implementation-ready product models.

My work sits at the intersection of product management, business analysis, and UX architecture. I align business goals, UX logic, AI/data constraints, and engineering realities to prevent rework and enable predictable delivery in complex systems.

In recent years I’ve worked extensively with AI-driven and data-intensive platforms, where precise product definition directly affects scalability, compliance, and delivery speed.

Core expertise:
- Product definition & architecture
- Requirements engineering (stakeholder needs → implementation-ready PRDs)
- UX architecture for multi-role enterprise systems
- Business analysis & BPMN process modeling
- Governance frameworks & decision logic
- AI-integrated product flows

Result: reduced ambiguity, accelerated delivery cycles, and improved cross-team alignment in complex environments.
