  • Content and Community Head at Kide Science
    Jul 2021 - Mar 2023 ยท 1 yr 9 mos

    I worked with an incredible team at Kide Science. I wrote and ideated on almost everything in and out of our product, like blogs, socials, email funnels, and ads. We experimented often and nimbly - and had a lot of fun doing it! My responsibilities included: - Copywriting ads/landing pages/any touch points in the product - Writing blogs, podcasts, and both paid + organic social posts - All customer success in English - Community + customer outreach - Using user insights & data to inform every single decision along the way! Here's some of the things achieved: ๐Ÿ’Ž Increased sign-up conversion rates from 23% to 65%. We did various experiments to shift from time-based segmentation to behavioral segmentation for user communications (this also increased our self-serve freemium-to-paid CR from 0.1% to about 2%!) ๐Ÿ’Ž Increased our revenue by nearly 200% by overhauling our pricing and packaging ๐Ÿ’Ž Decreased our paid social CPA to around ~$2-3 (from ~$8-12) for new free signups. ๐Ÿ’Ž Shaped up the brand + tone of voice for Kide and my colleagues. This is hard to quantify, but our customers and networks know and love our messaging.

  • English Second Language Instructor at GoGoKid
    Aug 2019 - Jul 2021 ยท 2 yrs

    I taught English as a second language to Chinese kids remotely. I built up a base of students through marketing myself to parents and children overseas, and have taught over 1,600 one-on-one classes to over 100 kids. Initially, I started this gig to support myself through my Master's program - but I really fell in love with both the job and the smiling faces I would see every day.
