Translation & acquisition
SayHey!
SayHey! was a translation app built for travel’s return after COVID—when people were moving again but still wanted communication that felt human, not like a phrasebook. It centered expressive, personalized messaging across eighteen languages, with typography and color treated as part of what you were actually saying abroad.
As the app found traction—including a strong run in Travel on the App Store—the naming rights and related IP were acquired, turning a lean, independently shipped product into a commercial asset with a clear ownership story.
Later, 7T acquired the company behind SayHey!. That transition led directly to joining 7T—carrying the same craft in React Native, product polish, and end-to-end delivery from SayHey! into broader mobile and platform work.
Neomorphism & hair forecasts
FrizzCheck
FrizzCheck is a weather-aware hair utility wrapped in a neomorphic interface—soft extruded panels, gentle depth, and quiet contrast—so the experience feels tactile and calm instead of like another loud forecast app.
Behind the UI sits a custom good-hair-day prediction pipeline that blends live conditions with a personalized hair profile (type, texture, porosity, and density) to turn humidity, trends, and weekly outlooks into a clear, immediate read on how your hair is likely to behave.
On release it resonated strongly in China—where the proposition had to read instantly—and sold well there out of the gate, validating a narrow, opinionated consumer product built for quick daily decisions.
