Redesign faktur.site landing page

Oauth sign in card design

I’ve been building Faktur, a modern invoice management system using Next.js 16, tRPC, Drizzle ORM, and shadcn/ui. It handles invoices, clients, business profiles, payments, and generates clean PDF invoices. You can try it here: faktur.gustifaizal.com

I made Taxana, a crypto tax calculator for Solana Dex traders in Indonesia. It pulls your swap transactions, computes everything with FIFO, calculates PPh Final 0.2% on sells and PPN 0.22% percent on buys, then generates a full PDF report for SPT. ps: It’s a helper tool, not tax advice, so double check with a tax consultant.
