Now I'm back, and instead of jumping straight into job applications, I decided to spend some real time leveling up first.</p> <p>Here's what I'm currently working on:</p> <h2> Migrating one of my projects to TypeScript + Next.js </h2> <p>I built FoodFlick — a food-ordering app with live restaurant data — a while back in plain JavaScript with Create React App. I'm now rebuilding it properly: TypeScript for type safety, Next.js App Router for the routing and rendering model most companies are actually using now.</p> <h2> Learning frontend performance optimization alongside it </h2> <p>Rather than treating the migration as just a syntax change, I want to use it as a chance to actually measure and improve things — Lighthouse scores, bundle size, load times — not just get the code compiling.</p> <h2> What's next </h2> <p>I'll be writing about both as I go, including what breaks, what confuses me, and what I learn fixing it. If you've done a similar migration or have advice on structuring a Next.js App Router project well, I'd genuinely like to hear it.</p> react webdev typescript nextjs
