👋 I’m Debbie Widjaja — a product leader with 15 years of experience across some places I’m genuinely proud to have worked.
Fighting hate speech and misinformation at Meta.
Helping over 3 million merchants at Shopify fulfill orders more efficiently.
Empowering customers to reduce their energy bills at Bulb, Europe’s fastest-growing green energy company.
Building AI-powered tools that opened doors for underrepresented young people at Multiverse (UK's first ed-tech unicorn) and Zero Gravity (Sifted’s UK fastest growing ed-tech 2025).
I’ve been writing about product management classics and first principles on Medium for years. Now I write The Shift for product managers trying to figure out what those principles mean in the age of AI — how the work is shifting, what skills still matter, and how to make good decisions when the rules keep changing. I don’t have all the answers, but I’ve been asking the questions long enough to have something useful to say.
