Tan P.

I help fintech and SaaS teams ship secure web applications when authentication, permissions, payments, and customer data cannot be an afterthought. I bring 10+ years with React, Next.js, Node.js, and PostgreSQL across banking and enterprise SaaS. At ACB, I built an Open Banking developer portal used by 200+ partners, the OAuth2/Keycloak access layer behind it within PCI DSS scope, and the UI for a mobile banking app with 100,000+ active users. I help with: • Next.js / React / Node.js applications on Supabase or PostgreSQL • Multi-tenant systems, roles, permissions, data isolation, and auditability • OAuth2, SSO, Keycloak, Supabase Auth, and row-level security • Stripe, invoices, financial dashboards, reports, and API integrations • Taking over an existing codebase and shipping safely Selected work: • Built AusBiz Capital (now Surestone Capital), an Australian investment platform with Next.js and Supabase • Built the Getahead job marketplace; the company later announced a $1.38M pre-seed round • Reduced checkout abandonment by 18% after redesigning the purchase flow • Cut infrastructure costs by about 35% by rebuilding the deployment pipeline How I work: Async-first, with clear written updates and short Loom walkthroughs. I overlap with US mornings or evenings and use calls only when they save time. If your product handles money or sensitive data and you want it built properly, send me a message.
