Founder of CLOOMS · Independent Developer
Jack Shi is an independent developer and the founder of CLOOMS, an independent digital-product company built on one ethos — usefulness over noise, clarity over complexity. Under CLOOMS he builds and runs a portfolio of focused tools and web utilities, including Home Cafe Lab.
He began his career at Alibaba's International Commerce Business Unit (ICBU) in 2008, then went independent to build the practical tools he saw people missing. Everything on Home Cafe Lab is brewed, spilled, and retested in a real kitchen before it goes live.
His guiding principle across everything he builds: find a real, specific need and solve it as simply as possible.
