Hello, I’m Summer
Product Owner | Project Manager | Scrum Master
Summer Tan
Turning complex requirements into shipped products — with Agile teams, clear priorities, and a steady hand on the timeline.
8+ Years Leading Cross-Functional Teams & Brand Curation
Product Owner at Qornerstone Pte Ltd, based in Singapore. I’ve spent eight years in software delivery — as a Business Analyst, Project Manager, and Scrum Master — working with clients across e-commerce, healthcare, and retail. I lead development teams, run Scrum ceremonies, and use tools like JIRA, SQL, and Power BI to keep work moving and decisions grounded in data.
Alongside the corporate work, I’ve founded and run two gifting brands. Glammy Gift & Florist curates bespoke floral arrangements for weddings, gifting, and seasonal occasions — grown through social media and positioned as a go-to seasonal trend. The Everyday Men is a curated gifting brand for men, sourced directly from China suppliers, with branding and packaging I designed end-to-end in Canva, Adobe Illustrator, and Adobe Photoshop.
Two sides of the same instinct: turn fuzzy ideas into shipped products people actually want.
