Selected work

I mapped and designed Matcha’s multiwallet flow, bringing connected wallets and network details into one menu for the decentralized trading platform. I covered wallet selection, adding a wallet, and loading, empty, and error states, so people can switch wallets during a trade without losing their quote or inputs.
I redesigned the homepage for Matcha, the decentralized trading platform by 0x, around the ways people begin a visit. I led the page structure and content hierarchy, giving new and returning users direct paths to search for a token, browse the market, connect a wallet, and start trading.
Popparazi V1I designed an early discovery feed for Popparazi, a social photo app. The work brought together friend suggestions, featured photos, and recommendation patterns, while exploring content density and the visual style for V1. It established the structure and interactions for the team’s early product iterations.
Shared family storiesI designed the story feed, moment detail view, and commenting patterns for a private family memory app. Stories group photos and clips by period, with dates, comments, and likes attached to each moment, so families can browse their memories and keep the conversation with the story it belongs to.
Matcha RewardsI designed the campaign artwork and variants for Matcha’s weekly rewards program on its decentralized trading platform. The key visual puts the leaderboard, cash prizes, trades, referrals, and points behind the headline, giving the launch, weekly countdown posts, and link previews one shared visual system.

1 of 5. BASED FLOYD VIII. @basedfloyd888: matcha has dope product designers.

Protector bookingProtector lets people book short-term personal security. As the sole product designer for the booking experience, I designed the steps for choosing a protector, selecting how they should be dressed, and adding escorted transportation. Each part of the service can be selected and confirmed in one guided flow.
Matcha token pageI led the page structure and interactions for token research and trading on Matcha, the decentralized trading platform by 0x. The page brings market data, charts, trade controls, and order history together, so people can review a token and start a trade without changing views.
Matcha trade pageI defined the information hierarchy and interactions for Matcha’s main trading workspace. It brings the live quote, chart, balances, open orders, and trade history into one layout, so people can place a decentralized trade and follow its activity from the same page.
Dealership lead hubI designed a lead hub for a dealership retention platform, helping staff find sales and service opportunities in their existing customer base. I owned the layout, outreach metrics, retention comparisons, filters, and bulk-send flow, so staff can see how outreach performed and send a filtered batch of customers to the dealer app without leaving the page.
Matcha on mobileI led the mobile trade journey for Matcha, the decentralized trading platform by 0x. I adapted token details, the trade form, review, and confirmation for phone screens, including the layout, touch targets, and order of information, so people can research and trade from a mobile browser.
Matcha ProI led the product structure and interaction design for Matcha Pro, a decentralized trading workspace for active traders. Live charts, token signals, transactions, and order management come together in a denser layout, giving advanced tools a dedicated home alongside Matcha’s standard swap experience.
I designed the GoPlus token-check integration for Matcha, the decentralized trading platform by 0x. The work covers source code, tax, minting, and honeypot signals, along with loading, pending, warning, and result states, so people can review common token warnings while preparing a swap.

About Rafael Medina

About me

I design the complicated parts of products people prefer not to think about. I figure out what to build, test it with real people, and prototype in code because working interactions answer questions faster than static mockups.

When I’m not working, I’m probably kickboxing, swimming, riding a bike, or being humbled by salsa and jiu jitsu.

  • Kickboxing
  • Mountain biking
  • Lap swimming
  • Hiking
  • Salsa (learning)
  • Jiu jitsu (learning)
