SUMMARY
Senior Product Designer with 10+ years of experience, including 6+ years shaping a live, high-complexity consumer
product end to end. I work in the messy middle of product design, taking vague or shifting requirements and turning
them into structured, scalable systems that hold up as the product grows. I care as much about product logic as UX:
defining how features should behave, removing ambiguity, and tying design decisions back to clear business goals.
I'm comfortable owning complex problem areas from first principles to launch, working closely with PMs, analysts,
engineers, and stakeholders to ship practical solutions.

EXPERIENCE

SENIOR PRODUCT DESIGNER, RockOne
May 2020 - June 2026
Owned design for complex product areas across a live consumer platform with a large, active user base, driving
much of its evolution from a small set of original games into a broader, more mature product ecosystem.
• Designed the end-to-end onboarding experience for new users, defining user flows, edge cases, and rollout
stages to deliver a clearer first-time experience with fully documented implementation logic.
• Owned the design of the Rewards Hub, consolidating multiple retention mechanics into a unified engagement
system that gave users a clear reason to return daily.
• Redesigned a core game mode to support additional game modes, larger player counts, teams, and bots,
creating a scalable architecture while receiving highly positive user feedback.
• Built the product's design system from scratch and later rebuilt an inconsistent external design system,
establishing a scalable design foundation and improving design-to-development handoff efficiency.
• Mentored a product designer, contributed to product strategy, and led multiple features from concept to launch,
helping scale the design function and expand the product offering.

SENIOR PRODUCT DESIGNER, Provectus (Reinvently)
Sep 2019 - Apr 2020
• Delivered wireframes, prototypes, and scalable design components across an outsourced portfolio of projects in
different domains, including a healthcare mobile app, a self-service laundry kiosk and companion app, and a bus
rental booking app, adapting quickly to different product types and domain requirements.
• Took a landing page project from a client's raw idea through to a structured product concept, working with a
business analyst to build a business model and an AARRR framework before moving into wireframes and design,
giving the client a validated product direction and a working feedback funnel.

SENIOR LEAD DESIGNER, Steelkiwi (Globaldev Group)
Sep 2018 - Aug 2019
• Owned hiring and onboarding for a 4-5 person design team, running technical interviews, reviewing test tasks,
and introducing regular 1:1 check-ins to build a repeatable screening and onboarding process.
• Provided technical mentorship by reviewing designers' work and unblocking questions, and mediated delivery
conflicts between design and sales when timelines slipped, keeping the team functioning through recurring scope
and deadline pressure.

UI/UX DESIGNER, Steelkiwi (Globaldev Group)
Mar 2016 - Aug 2019
• Owned UI/UX end to end for a large-scale collaboration platform connecting startup founders with freelance
teams, with distinct permission levels across roles and a blockchain-based contribution system shaped over
multi-hour stakeholder workshops, delivering a genuinely data-heavy, feature-rich product structure.
• Designed UI/UX end to end across a wide range of domains and markets (Europe, US, Asia), taking products
from an early, often basic idea through to full-scale delivery, including banking admin panels, a healthcare app,
self-service kiosks, and a multi-role beauty-service app, one of which received a Tappawards App of the Day
recognition.

Earlier (2013-2016): UI/UX and product design roles across agencies and freelance, covering web, mobile, and
dashboard products, including a senior/lead role managing a small design team.
