Problem Space

Why Speaking Skills Stall in Language Apps

Popular apps like Duolingo often just mark speech as "correct/incorrect," without clarifying why it's wrong.

One user lamented:

"After trying over 30 times, my pronunciation of 'J'aime le zoo' never gets accepted…."

Impact

Translating Design into Metrics

As the founding designer, I drove LingoEcho from concept to launch and helped the team secure funding from YC China.

I built the brand and product experience from the ground up, transforming 2D illustrations into a cohesive UI system and delivering a responsive frontend that aligned design and engineering. My work enabled the team to ship a compelling MVP and position LingoEcho as a standout solution in a crowded language learning space.
