Curriculum Vitae

Renzo Bogdan Guereschi

Senior Product Designer with 6+ years across B2B SaaS, platform tools, complex systems, and AI-native product workflows. I work end-to-end, from discovery and problem framing through prototyping, testing, and delivery, often in ambiguous environments where defining the right problem is critical. I focus on reducing ambiguity in complex systems and making key product decisions clearer for users, aligning user behavior with business outcomes. Experienced collaborating with PMs, engineers, and executives to drive product decisions. Comfortable across web and mobile. Experienced in AI-native product and development workflows, combining spec-driven design, structured implementation planning, and AI-assisted development to accelerate delivery and reduce design-to-engineering friction.

Senior Product Designer
Tree-Nation · Remote · Greentech / B2B & B2C SaaS
  • Users registering from corporate gift flows were selecting the wrong account type, breaking CRM routing. Reworked the onboarding decision model by clarifying user intent at the selection point, introducing better defaults and reducing ambiguity. Improved classification accuracy by 70%+.
  • Payment failures lacked visibility and recovery paths. Designed a payment management layer with saved methods, expiry visibility, and retry flows (including SEPA), improving error recovery and recovering ~20% of failed payments.
  • Designed the subscription model end-to-end, defining pricing structure, entry points, and lifecycle interactions. Contributed to +80% revenue growth.
  • Worked directly with CEO and PM to define scope, prioritize problems, and align product decisions without intermediaries.
  • Built and scaled a multilingual design system across web and mobile, supporting consistent patterns for both B2B and B2C flows.
  • Took ownership of the React Native frontend for the mobile app, combining spec-driven workflows and AI-assisted development to bridge design and implementation.
  • Used structured implementation planning and AI-assisted workflows to accelerate prototyping, frontend iteration, and collaboration with engineering teams.

UX & Product Designer
Cycloid · Remote · Developer Tooling / B2B SaaS
  • Designed the Quota Management feature, translating complex infrastructure constraints (resources, permissions, usage limits) into a usable interaction model. Created a central asset table with filtering and visibility across teams and usage states, plus inline indicators where limits could be reached.
  • Reduced cognitive load in a highly technical domain by structuring information hierarchies and exposing constraints progressively, allowing users to understand limits without needing deep system knowledge.
  • Ran discovery interviews and usability testing with DevOps engineers to validate problem framing and iterate on solutions before implementation.
  • Contributed to the design system, defining reusable patterns for data-dense components and multi-step configuration flows.
  • Partnered closely with engineering to navigate technical constraints and trade-offs while preserving clarity in the user experience.
