CellCarta
CellCarta runs precision medicine lab services, with sites in Canada, the US, Belgium, Australia and China. Valtech looks after its digital channels in China: the WeChat Official Account, a mini program and a mobile website. I worked on them in both of my Valtech internships, on three editions of CellCarta's yearly event and on the everyday content in between.

One event, three editions
Shanghai, May 2025
An invitation-only forum for people working in pharma and biotech, held on 21 May 2025 with speakers from Shanghai Pulmonary Hospital, AstraZeneca, Johnson & Johnson, MSD and CellCarta. I designed the online materials in Chinese and English: the registration page in the mini program, the invitation, the Official Account article, the home page banner, the cover of the meeting guide and the thank-you image after the event.
Four header directions for the registration page. I generated the backgrounds with GPT and Midjourney.

Shanghai, May 2026
The second edition, on 20 May 2026, co-organized with the US Chinese Anti-Cancer Association. Another intern made the early drafts. I took over from the 20 April version and carried it through to delivery. The layout follows the 2025 page, in blue and violet this time. I made the registration page, a 600 px email version and the event covers.

Beijing, September 2026
An international symposium on biomarker innovation in the ADC era, held in Beijing on 21 September 2026. The brief came with limits:
- The page is built from image slices in the mini program's CMS, so the booking button is drawn into the header image.
- The Official Account version drops the button and ends with a follow-us card.
- Speaker cards follow the order of the talks, and the agenda can't be a table.
- No text below 12 px, since many readers are senior specialists.
The client kept the original layout and chose a starry gradient for the header. Final files went out on 4 August. I also cut out and matched the headshots of the five speakers so their cards line up.

An article template that stayed
CellCarta wanted an Official Account layout it could reuse. In July 2025 I made a template in a red and a blue version: cover and header templates at 1:1 and 2.35:1, two sets of section titles, dividers, body text rules, mini program cards and a follow-us card for the end of each article. The account still uses this layout.
In 2026 I made the covers for CellCarta's partnership news with Leica Biosystems, Sonic Healthcare and Tempus AI.

The mobile website
Contact Us button
The floating Contact Us button on the website and the mini program was easy to miss. I made it larger and gave it a brand color and a shadow. The change is live.

FAQ and global sites
In July 2025 I also designed mobile pages for an FAQ and for CellCarta's sites around the world: two list styles for 22 questions, a set of 16 line icons, and a map with a card for each site. Both were design proposals.

A desktop Solution page
In June 2026 the account lead asked for a desktop version of the Solution page, based on the mobile site. My first version was mostly black and gray. By the fifth, each service had a pair of color squares taken from the logo, a thin band of brand color under each photo, outlined red buttons and a Load more button at the end. It was a design proposal as of September 2026.
