I built an editor that lets me write a React animation, watch it run as I type, and publish it as real code to my repo — and this whole post is explained by the animations it produced.

The final post in the Lumo series — everything I learned from building a full-stack personal finance app from scratch, the mistakes I'd avoid, and what comes next.

Building security for a finance app — device approval workflows, multi-layer rate limiting, subscription tiers, and GDPR compliance. The unglamorous stuff that keeps data safe.

Every app needs an admin panel. Here's how I built Lumo's with Vite and TanStack Router — and why internal tools deserve real engineering effort.

Salary hits monthly. Freelance pays biweekly. Investments trickle in quarterly. Converting all of that into one budget number? Harder than it sounds.

Building a real-time finance app on Convex — what's magical, what's painful, and what I wish someone had told me before I started.

Building a custom budget cycle system that aligns with your actual payday — sounds simple, right? Three rewrites later, here's what I learned.

487 use client. 1,076 files deleted. We migrated TudoNum from Next.js 16 to React 19 + Vite and stopped pretending our SPA needed a full-stack framework.

Flutter didn’t fail me, but React Native’s Expo Router woke me up. A die-hard Flutter dev explores why trading Widgets for URLs and Hooks changed everything.
