About

Senior product designer with 20+ years across fintech, healthtech and entertainment. I design apps, web apps and sites around conversion, retention and trust.

Some results: 40% less operation time and near-zero errors in IADB’s high-value approval app; more than 10% monthly retention at FOX Sports without removing ads; faster morning check-ins and sustained daily use at Biostrap.

For 9 years I led design at Qubika, scaling the team from 1 to 60 people with attrition below 6%.

What I do: product strategy, user flows and architecture, wireframes and prototypes, high-fidelity UI and design systems.

Challenge Sporadic use and weak retention: the challenge was sustaining the habit. What I did Predictive insights, quick tracking and a calm, low-friction interface. Result Higher engagement and retention, a high usability score and daily use even without symptoms. Healthtech & femtech · Mobile app · Product design

Challenge Low user trust: transactions with ambiguous states and money that felt half lost. What I did Centralized the cards in the wallet with one spendable balance, one status language for cards and transactions, and top-up in three taps. Result Fewer support tickets, faster top-up and clear transaction status. Fintech & wallet · Mobile app · Product design

Challenge An unusual density of live data, many features and a maze-like navigation. What I did Visual hierarchy and predictable navigation, with fewer options at once: the interface reads the user's focus and offers the relevant actions right there. Result A cleaner surface with the same data density, intuitive navigation and fewer false steps per session. Fintech & trading · Mobile app · Product design

Challenge Clinical-grade wearable data across many metrics, to be read at a glance without flattening it. What I did Gave each metric its own visual form, understandable almost without reading and without losing depth. Result Faster morning check-in, better understanding of metrics and sustained daily use. Healthtech & wearables · Mobile app · Data visualization

Challenge The site was losing readers because of its own ad load; monetization had to stay without breaking the experience. What I did Instead of removing ads, reorganized the reading flow with a Breaking News hierarchy and ad modules at natural break points. Result More than 10% monthly retention, better ad CTR and faster time to market. Media & sports · Web · Product design

Challenge Executives approving high-value transactions on the go, where an approval mistake was costly. What I did A zero-friction approach and a "one screen, one decision" principle to reduce cognitive load and prevent accidental approvals. Result 40% less operation time, an error rate close to 0% and immediate adoption. Fintech · Mobile app · Product design
