I'm John Pham — a DevOps and platform engineer with 8+ years delivering enterprise software for millions of users, and an advocate for cultivating a strong DevOps mindset, practices, and tools that ship real value.
Today I'm a Senior Platform Engineer at Storable. Most recently I co-founded My Private Ledger, a B2B fintech SaaS I scaled to 100+ agencies. Before that, as Lead DevOps Engineer at MasterCard, I kept the UK's #1 real-time scam defence — Consumer Fraud Risk — running for 11 of Britain's biggest banks, catching fraud before the money's gone. NZ citizen, with full work rights in Australia and New Zealand.
